How Japan is Preparing for War With China

How Japan is Preparing for War With China

RealLifeLore

0:00 Tensions between Japan and China have recently ratcheted up to the highest

0:03 level they've been since the end of the Second World War.

0:06 The current crisis between them began on the 7th of November 2025,

0:10 when Japan's new Prime Minister, Sanae Takaichi,

0:13 was asked point-blank in the Japanese Diet what might

0:16 prompt Japan to exercise the policy of collective self-defense.

0:20 Now, it's important for you to understand

0:22 the context behind this particular phrase in Japanese politics.

0:26 Japan's constitution,

0:27 drafted after the end of the Second World War under Article Nine,

0:30 explicitly reads that the Japanese people

0:33 forever renounce war as a sovereign right of the nation and the threat or use

0:37 of force as means of settling international disputes.

0:40 It has been under this constitution

0:42 after the horrors Japan experienced during World

0:44 War II that the country has remained a strictly pacifist nation for decades now,

0:49 and why modern Japan's armed forces have never

0:51 been referred to as an army or a navy, but as self-defense forces instead,

0:56 whose mission has always been restricted to the defense of Japanese territory

1:00 itself in the event that Japan comes under hostile foreign attack first.

1:04 But in 2015, spearheaded by then Prime Minister Shinzo Abe,

1:08 the Japanese government significantly reinterpreted Article

1:11 Nine of its constitution with a new security law that enables the self-defense

1:14 forces to exercise collective self-defense as well.

1:18 In essence, granting Japan the legal authority to deploy military

1:21 force abroad if it is in the defense of an ally

1:24 that has come under attack and if it is

1:26 judged to be necessary for the Japanese state's own survival.

1:30 So, fast forward back to the 7th of November in 2025,

1:33 when Japan's new Prime Minister, Sanae Takaichi,

1:36 was asked directly by the Diet what scenario exactly might

1:40 prompt Japan to actually invoke the policy of collective self-defense.

1:45 Her public answer was that if China

1:46 initiated an armed blockade or invasion of Taiwan,

1:49 it could constitute a survival-threatening situation for Japan.

1:53 With survival-threatening situation being

1:55 the all-important phrase she used here,

1:58 because it implied that she would trigger Japan's right

2:00 to collective self-defense in the event of a Taiwan

2:03 invasion or blockade scenario that would see

2:05 the self-defense forces deployed into the war against China,

2:08 even if Japanese territory itself was not attacked directly first.

2:13 It was truly a breathtaking and unprecedented statement in Japanese politics.

2:18 The first time ever that [music]

2:19 a sitting Japanese Prime Minister suggested publicly during

2:22 a formal session in Parliament that Japan might

2:25 intervene militarily against China during a Taiwan conflict.

2:30 And China's response since then has been a mix of shock and utter fury.

2:35 The very next day after Takaichi's remarks,

2:37 China's Consul General in Osaka responded with particular anger.

2:41 Writing on X, directly addressed to the Prime Minister herself, quote,

2:46 "If you stick that filthy neck where it doesn't belong,

2:49 it's going to get sliced off.

2:50 Are you ready for that?" End quote.

2:53 The post has since been deleted,

2:55 but further diplomatic attacks from Beijing have followed.

2:58 The Chinese have consistently demanded that Takaichi retract her statement,

3:02 which she has consistently refused to do.

3:04 China provocatively flew a drone between Taiwan

3:07 and the southernmost Japanese island of Yonaguni, that resulted in the Japan Air

3:11 Self-Defense Forces scrambling fighter [music] jets.

3:14 And then even more provocatively, they sent four Chinese Coast Guard vessels

3:17 into the territorial waters around the disputed Senkaku Islands,

3:21 a small group of uninhabited islands administered by Japan but claimed by China.

3:26 Beijing has also issued advisories warning against Chinese students

3:29 from studying in Japan or tourists from visiting Japan,

3:32 which the Japanese government has estimated might end up causing

3:35 more than $14 billion worth of economic damage to Japan alone.

3:40 China has also banned the importation of all seafood coming from Japan,

3:44 and they've recently begun shutting down and blocking Japanese

3:46 firms and other culture from the country as well.

3:49 As most embodied by a viral event that took

3:51 place on the 29th of November, when Maki Otsuki,

3:55 a Japanese singer who was performing her well-known theme

3:57 song for the anime One Piece on stage in Shanghai,

4:01 was forced off of the stage by Chinese officials in the middle

4:04 of her performance after the ban on Japanese

4:07 cultural content came more strictly into force.

4:10 And all the while, Takaichi has continually refused

4:13 to apologize or amend her statements in any way.

4:16 And not only is Japan busy reinterpreting what kinds of military

4:20 engagements they can get involved in from a legal perspective,

4:23 they're also busy backing their words up with enormous new amounts

4:26 of funding and arms for the Japanese Self-Defense Forces as well.

4:30 Frightened by Russia's invasion of Ukraine

4:32 and China's increasing hostility towards Taiwan,

4:35 Japan announced back in 2022 that they would be doubling their annual military

4:39 spending from 1% of GDP to 2% of GDP by no later than 2027,

4:45 equaling NATO military spending targets for the first time in Japan's history.

4:50 Shortly after she became Prime Minister in late 2025,

4:53 Sanae Takaichi announced that the timeline would be sped up by a year

4:56 early to reach 2% of GDP on military spending by 2026,

5:01 meaning the next year Japan will probably achieve

5:03 a defense budget of [music] around $80 billion a year,

5:07 putting it into the same ballpark as the UK

5:09 and near the top five highest military spenders on the planet.

5:13 A truly titanic shift for a country that even just five years ago

5:17 was so well known for its commitment to pacifism that not a single

5:22 soldier in the Self-Defense Forces has ever been killed in action by an enemy

5:26 in the entire history of Japan since the end of World War II.

5:30 But this shift in Japan's military posture has

5:33 been a long time coming, and to China,

5:35 Japan's rapidly increasing military spending and its

5:38 comments about intervening against them over

5:40 Taiwan are triggering deep and painful

5:43 historical memories and experiences from their past.

5:47 Because Japan and China have a long, complicated, and contentious history.

5:52 As the two most preeminent powers in East Asia,

5:54 they maintained relations with one another for thousands of years.

5:58 But in the late 19th century,

6:00 Japan was able to rapidly industrialize

6:02 and remain politically united and centralized,

6:05 which enabled it to take advantage of a historically weak and vulnerable

6:09 China that was still pre-industrial

6:11 and increasingly politically fragmented and decentralized.

6:15 Japan, more than any other single nation,

6:17 contributed the most to China's so-called century of humiliation.

6:22 And they inflicted more than 50 years of continuous pain and suffering on them.

6:27 It began with the First Sino-Japanese War between 1894 and 1895,

6:31 [music] in which Japan attacked China and emerged decisively victorious,

6:36 removing Korea from the Chinese sphere of influence

6:39 and forcing the Chinese to cede Taiwan to Japan,

6:42 which then remained a Japanese colony for the next half century.

6:46 Then a few years later in 1900,

6:48 Japanese troops participated in the suppression of the Boxer Rebellion

6:51 in China that resulted in tens of thousands of deaths.

6:55 Following the outbreak of the First World War in 1914,

6:58 the Japanese issued a series of secret demands to China

7:01 that came to be known as the 21 Demands,

7:03 which essentially demanded that the whole of China

7:06 subordinate itself into becoming a Japanese protectorate.

7:10 It only failed after China published the extreme

7:12 demands and sparked outrage by the British and Americans,

7:15 who pressured the Japanese to back down.

7:18 Later in 1931, the Imperial Japanese Army staged a false

7:21 flag attack that came to be known as the Mukden Incident,

7:24 which they used as their pretext to launch an invasion into Manchuria,

7:28 which they subsequently conquered and where they established

7:31 the puppet state of Manchukuo over in 1932.

7:34 Afterwards, the Japanese government encouraged a vast settler

7:37 colonial project in Manchuria to alter the region's

7:40 demographics that saw more than 1 million

7:43 Japanese settlers migrate into the territory by 1945.

7:48 Small clashes between the Japanese and Chinese armies continued on for years

7:52 until they outright exploded in a full-scale warfare in 1937,

7:57 when Japan launched a full-scale invasion across the rest

8:00 of China with the goal of outright conquest.

8:03 The ensuing Second Sino-Japanese War,

8:06 that lasted for the next eight years and spilled over into World War II,

8:10 ultimately became one of the deadliest conflicts in all of human history,

8:13 [music] resulting in the deaths of around 20 million people,

8:17 the vast majority of whom were simply Chinese civilians.

8:21 Throughout the war, Japanese forces perpetrated an almost endless

8:25 list of war crimes and atrocities against the Chinese people.

8:29 But the two most infamous examples that continues to strain relations

8:32 between the two countries today were the Nanjing Massacre and Unit 731.

8:37 Arguably two of the worst things that human beings have

8:40 ever done to one another at any point in our history.

8:44 After Japanese forces took control over the Chinese

8:46 city of Nanjing near the end of 1937, then the capital city,

8:50 they engaged in a brutal six-week-long rampage of mass murder,

8:55 looting, arson, torture,

8:57 and abuse directed against the city's Chinese inhabitants.

9:01 Newer estimates believe that up to 200,000 [music] Chinese people within

9:05 Nanjing were killed by the Japanese Army during this six-week massacre,

9:10 a rate of killing that is comparable to the Rwandan

9:13 genocide that would take place later in the 1990s.

9:17 Meanwhile, Unit 731 was a top-secret research facility that was operated

9:21 by the Imperial Japanese Army in occupied Manchuria throughout the war.

9:27 [music]

9:26 Unit 731 conducted large-scale research into chemical and biological weapons,

9:31 including brutal and lethal experiments conducted on live

9:34 human beings [music] who were usually abducted Chinese civilians.

9:38 Unit 731's victims were subjected

9:40 to deliberate deadly disease [music] infections,

9:42 chemical weapons and explosives testings, live limb amputations,

9:46 and live vivisections performed under no anesthesia so

9:50 as not to interfere with the potential results, [music] organ harvesting,

9:54 cold exposure and hypothermia testing, hyperbaric chamber testing,

9:58 and other brutal experiments that are collectively believed to have

10:01 killed around 14,000 [music] of humanity's most unfortunate ever victims.

10:08 Not a single person who ever entered into Unit

10:10 731's research testing is known to have survived.

10:13 While the biological weapons they developed led directly

10:16 to the deaths of at least another 200,000 more

10:19 people across Chinese villages and cities through the Japanese

10:23 army's deliberate contamination of water supplies and agricultural lands.

10:27 The legacy of these atrocities and Japan's 50-year war on China

10:31 continue to negatively impact relations between the two countries today.

10:35 And it frames the historical context in which China

10:38 often views Japan's modern military expansion that's currently taking place.

10:42 At the end of the Second World War,

10:44 when Japan was thoroughly defeated and occupied by the United States,

10:48 the country was made to surrender all

10:49 of its conquered territories back to China,

10:52 including Taiwan, and was made to adopt its new pacifist constitution

10:56 that renounced its right to war and the use of force forever,

10:59 effectively resulting in Japan's demilitarization.

11:03 [music] After suffering through millions of their own dead

11:05 over the course of the Second World War,

11:07 including the atomic bombings of Hiroshima and Nagasaki,

11:11 the Japanese public was left traumatized and wary of war as well,

11:15 easing their transition towards pacifism in the postwar years.

11:19 Without the legal right to ever go to war again,

11:21 Japan also agreed to become incorporated into the American

11:24 security umbrella with the 1950 security treaty, [music]

11:27 which guarantees that the US will defend Japan's territory

11:30 in the event of a hostile attack in exchange

11:32 for Japan granting the US the right to base

11:34 large numbers of military forces within their country.

11:38 This arrangement at the time was mutually beneficial,

11:40 as it enabled Japan to outsource all of their defense needs to America,

11:44 which allowed them to fully concentrate on rebuilding

11:47 and then developing their economy in the postwar years instead.

11:50 While it enabled America to control a huge and strategically valuable

11:54 rear base of military operations in East Asia that it has

11:57 been able to use to great effect during wars in Korea

12:00 and Vietnam and [music] in buttressing the position of Taiwan against China.

12:05 And yet, relations between Japan and China continued

12:08 remaining tense [music] despite Japan's new commitment to pacifism.

12:12 After the end of the Chinese Civil War in 1949,

12:15 Japan continued recognizing the Republic of China's

12:17 government based on Taiwan and didn't

12:19 normalize their relations with the People's

12:21 Republic of China for years until 1972.

12:25 After the Korean War broke out in 1950,

12:27 the US encouraged Japan to establish an armed police

12:30 force that eventually evolved into the Self-Defense Forces by 1954.

12:34 But for decades, as Japan relied on the US military for defense

12:37 and focused all of its energies on rebuilding and then expanding their economy,

12:41 the growth of the Self-Defense Forces was kept at a minimum.

12:46 [music] It was organized to be the bare minimum force necessary

12:48 to defend the Japanese home islands themselves from an outside attack.

12:51 And so, they resisted acquiring any and all offensive capabilities

12:55 for decades and continued only being allocated a minimal budget.

12:59 By the late 1970s, an informal cap on the Self-Defense

13:03 Forces budget of 1% of GDP per year

13:05 had come into effect that would last all

13:08 the way up until our modern age in the 2020s.

13:11 After the end of the Cold War,

13:13 Japan's position initially seemed to feel even more secure with the collapse

13:17 of the Soviet Union and their continued

13:19 privileged position within the US security umbrella.

13:22 And so, no major push to expand the role

13:24 of the Self-Defense Forces would come for another generation.

13:28 But then, all of a sudden, beginning in the 2010s,

13:30 [music] Japan's geopolitical situation would begin

13:33 growing increasingly precarious due to four

13:36 major developing reasons that are pushing the country to now re-evaluate things.

13:41 The first reason has been an increasingly bold and aggressive

13:44 North Korea on their doorstep that's now armed with nuclear weapons.

13:48 North Korea conducted their first successful nuclear

13:50 weapons test in 2006, and since then,

13:54 they've conducted six additional nuclear weapons tests with the most recent

13:57 one reaching a threshold of 160 kilotons worth of explosive power,

14:02 10 times the power of the Hiroshima atomic bomb.

14:06 The Stockholm International Peace Research Institute,

14:09 which tracks the nuclear inventories of countries from around the world,

14:12 currently estimates that as of January 2025,

14:16 the North Koreans possess around 50 active nuclear weapons and have

14:20 enough fissile material to produce another 40 more in due time.

14:24 They've also likely already acquired the capability

14:26 to mount one of these nuclear weapons

14:28 to ballistic missiles that can [music] impact

14:30 and destroy any city in the Japanese home islands,

14:33 making North Korea an existential threat

14:36 to Japan's own survival for the first time.

14:39 The North Koreans are also known

14:40 to possess around a thousand ballistic missiles,

14:43 hundreds of which have the range and capability

14:45 to impact targets in Japan with conventional warheads as well.

14:49 While multiple North Korean missile tests have begun flying

14:51 directly over Japanese territory itself beginning in August of 2017,

14:56 with further flyovers taking place in September 2017,

14:59 October 2022, and January 2025, further putting Japan on edge.

15:05 Even worse, North Korea has been growing increasingly closer to Russia

15:09 and more militarily capable since the invasion of Ukraine began, too.

15:13 To date, North Korea is the only UN member state other than

15:17 Russia itself to have formally recognized

15:19 Russia's conquests and annexations in Eastern Ukraine.

15:22 North Korea has provided Russia with millions

15:25 of artillery shells for the war effort, and most provocatively of all,

15:28 they've even deployed thousands of their own soldiers to fight

15:31 against the Ukrainians during the Kursk Offensive in Russia in 2024.

15:36 While recent Ukrainian intelligence released in November

15:38 of 2025 appears to suggest that North Korean

15:42 troops are active in the Russian-occupied parts

15:44 of the Zaporizhzhia region of Ukraine as well,

15:47 potentially making North Korea an active

15:49 belligerent in Ukraine's invasion as well.

15:52 North Korea and Russia have signed a renewed

15:54 military alliance pledging the two to the other's defense.

15:57 [music] While the Russians are known to be

15:59 providing the North Koreans with many of their most

16:01 advanced military technologies in exchange for all of the support

16:04 the North Koreans are giving them in Ukraine.

16:07 The end result is that with increasing military

16:09 technology and real-world modern battlefield experience in Ukraine,

16:12 [music] the North Korean army is growing more capable and dangerous,

16:16 while its nuclear arsenal continues to pose

16:18 an existential threat to Japan's very existence.

16:21 [music] The second and probably the most important

16:25 reason has been an increasingly powerful and assertive China.

16:28 [music] Between 2013 and 2022,

16:31 while US military spending only increased by 2.7%,

16:35 Chinese military spending rocketed up by more than 63% over the same time frame.

16:41 As of 2024, the US continues to maintain the highest military spending

16:46 in the world at $997 billion a year compared to China's $314 billion a year.

16:54 But while America's military is engaged all around the world,

16:57 [music] China's military is only engaged regionally in East Asia.

17:01 Beginning in 2010, as China's ambitions began growing with its power,

17:05 China has also increasingly begun clashing with Japan on a number

17:09 of territorial disputes that had remained dormant for decades beforehand.

17:14 Between 2010 and 2012,

17:16 the two countries clashed bitterly over the status of the Senkaku Islands,

17:21 a small group of uninhabited rocks that Japan [music] controls

17:24 but which China claims and calls the Diaoyu Islands instead.

17:28 In 2012, the Japanese government purchased three

17:31 of these disputed islands from their private owner,

17:33 which triggered huge [music] anti-Japanese protests in China who saw

17:38 it as a Japanese attempt to establish their sovereignty over them.

17:41 China attempted to pressure Japan by temporarily restricting

17:45 the export of rare earth minerals to them,

17:47 the first time that China seriously weaponized its

17:50 trade relationship with Japan over a diplomatic dispute.

17:53 At around the same [music] time,

17:55 China unilaterally issued an extended maritime EEZ claim in the East

17:59 China Sea that significantly extended into Japan's own-claimed EEZ area,

18:05 introducing a major maritime dispute between the two

18:07 countries that still remains in place today.

18:10 Then in 2013, adding on even further pressure,

18:13 China unilaterally declared an extension of their air defense

18:16 identification zone across the East China Sea as well,

18:20 incorporating the Senkaku Islands and significantly overlapping

18:23 with the air defense identification zone claimed by Japan,

18:26 escalating the conflict between them even more.

18:29 China's growing arsenal of missiles has also

18:31 been of a particular concern to the Japanese.

18:34 As of 2024, the Pentagon believes

18:37 that China possesses around 400 intercontinental ballistic missiles,

18:41 500 intermediate-range ballistic missiles,

18:44 1,300 medium-range ballistic missiles,

18:47 900 short-range ballistic missiles, and 400 ground-launched cruise missiles,

18:52 meaning that in other words,

18:53 China now possesses hundreds upon hundreds of missiles at its disposal

18:57 that can reach the Japanese home islands in the event of a conflict.

19:01 The point was delivered by the Chinese profoundly in 2022 [music] when

19:06 then US House Speaker Nancy Pelosi made an official state visit to Taiwan,

19:11 after which China initiated large-scale military exercises

19:15 encircling Taiwan that included multiple ballistic missiles

19:18 being fired directly into Japan's maritime EEZ

19:22 just south of the Japanese island of Yonaguni,

19:25 clearly illustrating China's capability to strike Japanese

19:28 territory or warships if they so desired.

19:32 China and Japan alike both understand that the status of Taiwan

19:36 going forward is a core national interest of both of them.

19:40 For Japan, a Chinese takeover

19:42 of Taiwan would simply be geopolitically disastrous.

19:45 [music] China would break the continuous

19:48 link in the so-called first island chain,

19:50 the line of islands that Japan, the Ryukyu Islands, Taiwan,

19:54 the Philippines, and Indonesia,

19:56 that box the Chinese coast in and contain the Chinese

19:59 Navy's ability to break out into the open Pacific.

20:01 [music] Since the waters to the west

20:03 of the line are relatively shallow and easier

20:05 to detect submarine activity in than the deeper waters to the east of the line.

20:10 All of the countries along the first island chain from Japan to South

20:14 Korea to Taiwan and down to the Philippines are staunch US allies.

20:19 But with a successful Chinese takeover of Taiwan,

20:22 the chain would be broken and the Chinese Navy

20:24 would finally be able to access the greater Pacific unobstructed.

20:29 From their control of Taiwan,

20:31 China could further increase their pressure on the Senkaku

20:34 Islands dispute and their dispute in maritime and airspace

20:36 areas with Japan that have serious implications on potential

20:40 offshore natural gas reserves in the area as well.

20:43 And potentially worst of all,

20:45 [music] Japan's critical sea lines of communication would become more

20:48 exposed to their historic rival than they've ever been before.

20:53 Japan is enormously over dependent on maritime trade to survive.

20:57 Nearly 90% of Japan's energy imports transit into the country

21:01 through vulnerable maritime choke points like the waters near Taiwan.

21:05 If these sea lanes are compromised during a conflict exploding over Taiwan,

21:09 Japan holds a strategic petroleum reserve that contains

21:12 232 days worth of net oil imports.

21:16 But they only have a strategic LNG reserve

21:18 that holds just 19 days worth of net LNG imports.

21:23 If the war blockade over Taiwan lasts longer

21:25 than 40 days and keeps the sea lanes compromised,

21:28 Japan would begin facing strategic paralysis and an economy that would

21:32 begin grinding down without the energy

21:34 imports they need to continue functioning.

21:37 Rerouted energy imports away from around Taiwan

21:40 would add both time and cost to them.

21:42 [music] And there's no guarantee that China wouldn't just take advantage

21:44 of their control of Taiwan afterwards to continue interfering with them [music]

21:48 to apply even more pressure on Japan's economy later.

21:52 These are the reasons why Japan has long maintained

21:54 a policy of keeping the Indo-Pacific region both free and open,

21:58 a term that they themselves first coined before the US adopted

22:02 the same policy by the same name under the Obama administration later.

22:07 There's also a concern that no matter what Japan does,

22:10 they won't be able to stay out

22:11 of a Chinese invasion or blockade of Taiwan for long.

22:15 The island of Yonaguni, the southwesternmost island of Japan,

22:18 is merely 110 km away from Taiwan.

22:22 As such, it's an extremely important location to control

22:25 for both China and the US during a potential conflict scenario.

22:30 Yonaguni and the rest of the Japanese islands in the Ryukyu

22:33 chain stretching up to Okinawa will be vital for both sides

22:37 to control [music] as they'll be critical for establishing aerial supremacy

22:40 and logistics routes for US forces

22:42 resupplying Taiwanese forces or counter-attacking Chinese positions.

22:47 The islands are a major component of the US

22:49 fish hook underwater sensor network that's critical for America's ability

22:54 to detect Chinese submarines that can mean a break out

22:56 from beyond the first island chain into the open Pacific.

23:00 While the US positions the bulk of their own

23:02 military forces stationed in Japan nearby in Okinawa,

23:05 where some 30,000 US troops are permanently forward deployed at.

23:10 If the US intervened during a Taiwan conflict, even if Japan itself didn't,

23:15 China would be likely to at least use their missiles

23:18 to bombard American bases and assets [music] in Okinawa.

23:22 And under extreme scenarios,

23:23 they might even attempt to launch amphibious operations

23:26 to try and seize the southwesternmost Japanese islands between Yonaguni

23:30 and Miyakojima in order to secure their northern flank around

23:34 Taiwan against potential US reinforcements and naval and air operations.

23:38 Thus, there are major legitimate reasons why

23:41 Japan fears that their territory could come under

23:43 attack or even under occupation and their economy

23:47 threatened by a Chinese assault on Taiwan.

23:50 There was also the risk military action taken

23:52 by China in the Taiwan Strait or military action

23:54 taken by North Korea in the Korean Peninsula could

23:57 encourage escalation by the other within their respective theaters.

24:01 [music] China might encourage North Korea

24:02 to ratchet up hostilities in the Korean Peninsula

24:05 in order to distract and tie down US and allied assets away from Taiwan.

24:10 And even if they don't do that, a full-blown Chinese

24:13 attack on Taiwan that draws in US assets would inevitably

24:16 present an opportunity for North Korea to take advantage

24:19 of the distraction and increase escalation on their own accord in Korea.

24:23 Thus, there is a major fear for Japan and America

24:27 that they could end up facing a two-front war in East

24:30 Asia under the worst-case scenario [music] with conflicts breaking out

24:33 in the Taiwan Strait and the Korean Peninsula almost simultaneously.

24:38 Even if none of that happens though,

24:40 the mere chance that North Korea might escalate in the Korean

24:44 Peninsula during a Taiwan conflict will force Japan and the US

24:47 to hold at least some of their resources in reserve rather

24:51 than being able to focus everything they have against China alone.

24:55 Okay.

24:56 Now, the third reason why Japan is reconsidering the Self-Defense Forces' modern

25:00 role is the Trump administration's wavering

25:02 commitments to defend US allies, including Japan.

25:06 Trump has publicly suggested that he wouldn't send

25:09 US forces to protect NATO states in Europe coming under attack who he felt had

25:14 not been paying their fair share towards defense.

25:16 And he's openly criticized the long-standing US-Japan

25:20 security treaty that's been in effect since 1950.

25:23 As recently as March of 2025, Trump plainly stated that he felt the security

25:28 treaty with Japan was unfair and a bad deal.

25:31 Because while it pledges the US to come

25:34 to the defense of Japan during an attack,

25:36 it doesn't pledge Japan to come to the US's

25:39 defense during an attack in the other direction.

25:42 Japanese officials were quick to point out, of course,

25:45 that the treaty is also what enables the US to station tens of thousands

25:49 of their troops in Japan across dozens of bases

25:52 that Japan ultimately bears the burden of hosting.

25:55 This has led to fears in Japan that the US might not

25:58 actually be serious about really assisting

26:01 them during an emergency scenario around Taiwan.

26:04 And knowing that the US military is globally engaged all around

26:07 the world while the Chinese military is only regionally engaged in East Asia,

26:12 Japan has felt the pressure to increase their own

26:15 military spending to help out and compensate or to hedge.

26:19 Then the fourth and final reason

26:21 for Japan's remilitarization was the precedent that was

26:23 set by Russia's full-scale invasion of Ukraine that was launched in early 2022,

26:29 showing clearly that massive wars of conquest launched by one

26:33 state against another wasn't a relic of the past.

26:36 Only months after the invasion began,

26:39 then Japanese Prime Minister Fumio Kishida warned that Ukraine

26:43 today may well [music] be East Asia tomorrow.

26:46 While polls showed that around 90% of the public believed that their country

26:50 needed to do more to prepare for a potential Chinese invasion of Taiwan.

26:55 And thus, because of all these various threats,

26:58 Japan has felt compelled to begin acting.

27:01 Evolving from the reinterpretation of the Constitution's

27:03 Article 9 in 2015 that has enabled Japan to act in collective self-defense

27:08 of its allies who fall under attack.

27:10 And then Japan's announcement within months

27:12 of Russia's invasion of Ukraine in 2022

27:14 [music] that they would double their defense spending at 2% of GDP by 2027.

27:20 And recently expedited to happen by 2026.

27:22 [music] In February of 2025, for the first time ever,

27:28 the Japanese Maritime Self-Defense Forces

27:30 provocatively sailed a destroyer directly

27:33 through the Taiwan Strait in order to send a message,

27:36 which triggered a spokesperson with China's

27:38 [music] Ministry of National Defense to say,

27:41 "Quote, China respects the navigation rights

27:43 of all countries under international law,

27:46 but firmly opposes any country creating trouble in the Taiwan Strait,

27:51 infringing upon China's sovereignty and security,

27:54 and sending wrong signals to the Taiwan independence separatist [music] forces.

27:59 End quote." And that incident was even

28:01 before current Prime Minister Sanae Takaichi's remarks,

28:04 [music] which suggested that a Chinese attack

28:06 on Taiwan would be interpreted by Japan

28:08 as a trigger of collective self-defense [music]

28:10 and would lead directly to an armed Japanese intervention.

28:14 So, what exactly is Japan planning to acquire

28:17 and do with its double defense budget?

28:19 First, and probably most controversially of all,

28:22 Japan plans to finally equip the Self-Defense

28:25 Forces with strike capabilities like long-range cruise missiles.

28:28 [music] Japan has since declared their intent

28:31 to purchase 400 US-made Tomahawk cruise missiles,

28:35 which can accurately strike targets up to 2,400 km away and which

28:39 can be equipped on Japan's naval assets like destroyers and submarines,

28:44 giving the Maritime Self-Defense Forces the ability for the first time

28:47 ever to strike targets deep within the Chinese or North Korean interiors.

28:53 This capability was long considered to be

28:55 taboo for the Self-Defense Forces to have.

28:58 Why, after all, should constitutionally

29:01 pacifist Japan possess these offensive weapons

29:04 with such long ranges capable of striking their enemies' territories directly?

29:09 To get around the optics of this acquisition,

29:11 Japan likes to use the term counter-strike capability

29:14 instead of strike capability when referring to the missiles,

29:18 emphasizing that they won't be used

29:20 for preemptive strikes against their adversaries

29:22 and will only be used after Japan itself comes under attack first.

29:27 In November of 2025,

29:29 a Japanese destroyer arrived in California to pick up the very

29:32 first set of these Tomahawk missiles that they have on order,

29:35 and hundreds more of them are soon to follow along with several hundred

29:39 other domestically produced long-range anti-ship missiles

29:43 that are being developed by Mitsubishi Heavy Industries,

29:45 called the Type 12 missile,

29:47 which will have a range of about a thousand kilometers.

29:51 Japan has also been steadily increasing

29:53 and approving their submarine Fleet as well.

29:56 Back in 2010 when the modern confrontation with China was just beginning,

29:59 Japan only possessed a fleet of just 16 submarines,

30:03 but it's grown to 24 of them as of today in 2025.

30:08 While all of Japan's submarines so

30:10 far conventionally powered by electric diesel engines,

30:14 the newest generation of Japanese submarines called the Taigei class

30:18 that was introduced in March of 2022 are extremely capable machines nonetheless.

30:23 [music] Nicknamed the sea ninjas by the Japanese,

30:27 they are very quiet and excellent for reconnaissance missions

30:30 and are capable of covertly deploying sea mines and launching torpedoes.

30:35 They're also expected to be armed with a US

30:37 supplied Tomahawk cruise missiles which will enable them to launch

30:40 long-range precision counter-strikes against

30:43 targets thousands of kilometers deep

30:45 within the Chinese interior if they decided do so.

30:49 Currently, the Japanese submarine Fleet consists of five of these modern

30:53 Taigei class subs and 15 older generation Soryu class subs,

30:57 but two more Taigei class subs are expected

31:00 to join the fleet and become operational by 2027.

31:04 And it will likely be these seven modern

31:06 and quiet subs that the Japanese Maritime Self-Defense Forces

31:10 would deploy to the southwesternmost Ryukyu Islands during

31:13 a Taiwan conflict where their mission would be to hunt

31:16 and attack Chinese submarines attempting to break through

31:19 the first island chain and to kill surface warships attempting

31:22 amphibious assaults on them and to potentially fire counter-strike

31:26 salvos of Tomahawks and military targets within China itself.

31:31 Japan's older generation of submarines and their surface warships, meanwhile,

31:35 would be dedicated to keeping Japan's sea

31:37 lines of communication and imports of oil and LNG as open and secure

31:41 as physically possible through escort missions with tankers.

31:45 Japan has also even inquired about potentially acquiring

31:48 US nuclear-powered submarines as well following recent American

31:53 agreements to provide them to other allies

31:55 in the Indo-Pacific region like South Korea and Australia.

31:59 Japan also intends to use its double defense spending to acquire

32:02 no fewer than 147 F-35 fighter jets from the United

32:07 States as well which will make Japan the second

32:10 largest operator of the F-35 only after the US itself.

32:15 The fighters will be capable of being armed

32:17 with long-range cruise missiles as well that, like the submarines,

32:20 will be capable of striking targets

32:22 deep within the Chinese interior if necessary.

32:25 105 of the F-35s on order by Japan will be conventional models,

32:30 but notably 42 of them will be the F-35B

32:33 short take-off and vertical landing model of the fighter.

32:38 [music] This is important because these are the F-35s that are being planned

32:41 by the Japanese to be deployed

32:42 to their upgraded Izumo class helicopter carriers.

32:46 Japan possesses two of these types of small aircraft carriers,

32:49 the Izumo and the Kaga,

32:51 which were of course originally designed to carry helicopters,

32:55 but now Japan is using the money they're

32:57 pouring into the military to retrofit and upgrade both

33:00 of these carriers to enable them to each transport

33:02 and launch up to 12 of the F-35Bs at a time

33:06 which together will give Japan one of the strongest

33:09 power projection capabilities in the world and will

33:12 enable them to fight more effectively for aerial supremacy

33:15 in hotspots like the East and South China Seas.

33:18 When they're completed around 2027, the Izumo and the Kaga will notably

33:23 become the first Japanese naval vessels to operate

33:25 fixed-wing aircraft since the days of the Imperial

33:28 Japanese Navy during World War II.

33:31 Many of the Mitsubishi Heavy Industries type 12 missiles are planned to be

33:35 stationed on the island of Kyushu by the spring of 2026 as well

33:39 which will give Japan extensive missile coverage from the safety of the home

33:43 islands across all of the Ryukyu

33:45 Island chain extending [music] across the southwest.

33:48 And across the parts of the island chain from Okinawa to Yonaguni,

33:52 the Japanese are planning even more preparations.

33:55 The island of Yonaguni closest to Taiwan is growing increasingly militarized.

34:00 The Japanese have already set up a surveillance radar

34:02 facility on the island and deployed an electronic warfare

34:05 unit there in 2024 that'll be used to jam

34:08 enemy communications and guidance systems around Taiwan's northern flank.

34:13 And in 2025, they confirmed that they'll shortly be

34:16 deploying batteries of medium-range surface-to-air missiles to the island

34:20 as well presumably to help guard against Chinese aircraft

34:23 and drones that might attempt attacks from this direction.

34:26 The island of Ishigaki further to the east

34:29 is being armed with anti-ship missiles while Miyakojima even

34:32 further to the east is being equipped with missiles

34:35 as well and is getting transformed into a hub

34:38 for air surveillance and ammunition storage depots that'll

34:41 be able to be accessed by Japanese and American

34:44 amphibious warfare units for counterattacks presumably coming down

34:48 the chain from the principal US military bases on Okinawa.

34:51 Beginning in November of 2025 as the crisis

34:54 between Japan and China [music] continued escalating,

34:57 the US Marines were observed to begin

34:59 conducting exercises moving supplies like fuel

35:02 and ammunition from Okinawa to Yonaguni presumably

35:05 to simulate establishing a forward operating base there.

35:08 While the Japanese themselves have also

35:10 begun training and creating a new amphibious

35:12 rapid deployment Brigade that's based on Kyushu

35:15 that is being modeled after the US Marine Corps and being tasked with a mission

35:19 of recapturing islands in the Ryukyu

35:21 chain that might fall beneath Chinese occupation

35:24 in the event of a full-scale conflict.

35:27 Within the city of Oita on Kyushu,

35:29 the Japanese are currently building four new large

35:32 ammunition depots that'll house anti-ship and ground attack

35:35 missiles positioning still more assets nearby to the Ryukyu

35:39 Islands in the event of a contingency.

35:42 Japan is also expanding its abilities to evacuate their citizens

35:45 in the event of a full-scale war in the Taiwan Strait.

35:48 If the worst comes to pass

35:50 and the southwestern Ryukyu Islands become a war zone,

35:53 Japan will seriously have to consider

35:55 the prospect of evacuating tens of thousands

35:58 of the island's Japanese residents to safety far away back on the main islands.

36:02 And so the Maritime Self-Defense Forces have

36:04 to be adequately prepared to carry that mission out.

36:07 And while it's not being actively considered yet,

36:10 it's always a possibility that eventually the Japanese

36:13 might calculate that the time has finally arrived

36:16 to acquire their own independent nuclear weapons arsenal

36:19 as well in order to guarantee maximum deterrence.

36:23 Japan possesses the technology, resources,

36:25 and technical expertise required to likely be

36:28 able to build a functioning nuclear weapon

36:30 in less than a single year's time if they really put their mind to it.

36:34 The only things that have so far prevented them

36:36 from doing so have been their own taboo against nuclear weapons,

36:40 US opposition, and the US security guarantees

36:43 that puts them under their nuclear umbrella anyway.

36:45 But in the event that those things change,

36:48 especially the US security guarantees, then Japan would almost certainly acquire

36:52 their own nuclear weapon rapidly to guarantee

36:55 deterrence against their nuclear-armed adversaries in China

36:58 and North Korea and potentially Russia, too.

37:01 Japan has seen the precedent of Ukraine who

37:04 surrendered their nuclear weapons in exchange for security

37:07 assurances only to become invaded and face

37:09 a war of conquest fewer than 30 years later.

37:12 In the event of a Taiwan conflict,

37:14 Japan could conceivably respond in one of four

37:17 different ways with varying levels of escalation and risk.

37:20 [music] In one scenario,

37:22 Japan might choose to take a strictly defensive stance declining

37:26 to trigger its security law for collective self-defense [music] and choosing

37:29 instead to focus on surveillance and missile defense over

37:32 the Ryukyu Islands and evacuating its citizens if and when necessary.

37:37 This approach might keep Japan out of the conflict,

37:39 but it would inevitably cause great harm

37:42 to Japan's relationship with the United States.

37:45 Under a second scenario, Japan could take a slightly more aggressive

37:48 approach and provide logistical support to American

37:51 forces in the conflict allowing the US to access fuel and ammunition depots,

37:55 utilize their bases for air and naval operations,

37:59 and using their Maritime Self-Defense Forces

38:01 to keep the sea lines of communication open.

38:04 Under this scenario, the Self-Defense Forces would still at least

38:07 be trying to avoid direct conflict with China, but China might still come to see

38:12 Japan as heavily assisting the American war effort

38:16 which might expose Japanese territory to retaliatory attacks

38:19 and still drag them into the war anyway.

38:21 Under a third and much more aggressive scenario,

38:24 Japan could simply choose to invoke its right to collective self-defense

38:28 by declaring an assault on Taiwan a survivable threatening crisis for them,

38:33 but still try and avoid direct combat around Taiwan itself.

38:37 Instead, the Japanese Self-Defense Forces could focus

38:39 on safeguarding the Ryukyu Islands by intercepting Chinese aircraft,

38:43 drones, missiles, submarines,

38:45 and ships attempting to attack or break through them.

38:48 While their warships could escort American naval

38:50 vessels through critical Maritime choke points nearby

38:53 Taiwan like the Miyako Strait in the north and the Bashi Channel in the south.

38:58 A final, fourth, and dramatically more aggressive option they could take

39:01 would be to fully commit the Self-Defense Forces to heavy combat

39:05 operations in and around Taiwan itself which might involve firing their new

39:10 long-range cruise missiles to strike military targets within China itself which,

39:16 of course, would make Japan a direct combatant in the war

39:19 and possibly incur the full wrath of China in retaliation.

39:24 Regardless of which option Japan might ultimately choose

39:26 to take if and when a Taiwan contingency actually materializes,

39:30 the country also faces significant

39:32 domestic problems towards its re-militarization drive.

39:35 For one thing, there's major issues on how exactly to pay for it.

39:39 Japan already has one of the highest national debts

39:42 in the world as a percentage of their GDP,

39:45 currently standing at around 237% nearly double

39:49 the debt ratio of the United States.

39:51 Tacking on even more debt to pay

39:53 for the military expansion is a difficult prospect,

39:56 which leaves the unpopular choice of increasing taxes

40:00 in the country to pay for it instead.

40:02 A politically difficult option since Japan already has very high tax

40:06 rates due to the country's rapidly aging population and social welfare programs.

40:11 And speaking of aging populations,

40:13 Japan has a critical shortage of available manpower to fill their ranks as well.

40:18 The numbers of young men in Japan aged between 18 and 26,

40:22 the prime age for military service,

40:24 peaked more than 30 years ago back in 1994 at around 17 million.

40:30 By 2020, that number of young military-age men in the country had shrunk to only

40:34 11 million and it is projected to further shrink beneath 8 million by 2050.

40:40 Fewer than half the numbers of young men available they had in the 1990s.

40:45 Low pay, tough work, low unemployment in the private sector,

40:49 and the limited prestige of serving in the armed forces of a constitutionally

40:53 pacifist nation have further discouraged recruitment

40:57 among the shrinking pool of manpower,

41:00 meaning that the Self-Defense Forces have missed

41:02 the recruitment targets every single year since 2014.

41:06 Moreover, the Self-Defense Forces,

41:08 like any credible or relevant real-world combat experience today.

41:12 The last time that a Japanese soldier is known

41:15 to have been killed in action was back in 1972.

41:18 And that guy was a fanatical holdout from World War II who died

41:23 in a shootout with police in the Philippines

41:25 decades after the war had already ended.

41:28 The Self-Defense Forces themselves have never once experienced

41:31 a fatality in combat in their entire history.

41:34 Will they and the Japanese public

41:36 at large actually be prepared for potentially enormous

41:40 rates of casualties during a major hot war with China and or North Korea?

41:46 I don't know, but overcoming these issues will

41:48 be a significant hurdle for Japan to overcome.

41:52 Neither Japan nor China currently seeking war with each other,

41:55 but the legacy of their shared histories and their mutual

41:58 military preparations in the present are increasingly making each other nervous,

42:03 causing a cycle of increasingly hostile rhetoric and actions.

42:07 Xi Jinping's China is determined to establish

42:10 the authority of the Communist Party over Taiwan.

42:13 In their eyes, finally unifying China in the process

42:17 and ending the legacy of China's century of humiliation.

42:20 If Japan intervenes,

42:22 China will see it as nothing less than a historical showdown like

42:25 the last time Japanese forces overran Taiwan in the late 19th century.

42:29 [music] As is already being shown

42:31 in modern Chinese propaganda like this example,

42:35 they will interpret a Japanese intervention as a Japanese

42:38 attempt to prevent the unification of their country.

42:41 While the Japanese will interpret a Chinese attack

42:43 on Taiwan as a dangerous act of aggression

42:46 that'll threaten their long-term stability and their citizens'

42:49 lives on the small Japanese islands nearby.

42:53 Neither side wants war, but neither side will be willing to back

42:57 down when the stakes are also this high.

43:00 In Japan's view, as once said

43:02 by the legendary Japanese samurai Miyamoto Musashi,

43:06 it is better to be a soldier in a garden than a gardener in a war.

43:11 In some ways though, Japan has been in a hostile confrontation

43:14 with its neighbors in East Asia for longer

43:16 than most people are probably aware of, especially when it comes to North Korea.

43:21 Though North Korea has repeatedly fired

43:23 missiles over Japanese territory since 2017,

43:26 the North Koreans have also done much worse

43:28 than that to the Japanese in earlier decades.

43:31 Between 1977 and 1983,

43:33 hundreds of Japanese people began mysteriously disappearing without a trace,

43:38 usually along the country's coastlines.

43:41 For decades, there were no clear explanations for all

43:43 of these disappearances because they were usually just ordinary average people.

43:48 For a long time, the disappearances were the subject

43:51 of various conspiracy theories among the Japanese public.

43:54 Some of them even outlandishly purporting that North

43:57 Korea was somehow behind all of them,

44:00 though hardly anybody actually believed that.

44:03 That is until decades later in 2002 when Kim

44:08 Jong-il just outright confessed to the Japanese prime minister during

44:12 a meeting that his country had indeed secretly abducted at least

44:16 13 Japanese citizens in the past and apologized for them.

44:21 Since then, the Japanese government has formally recognized that at least 17

44:24 of their citizens were abducted by the North Koreans between 1977 and 1983,

44:29 though independent investigations believe that the true

44:31 number is likely in the hundreds,

44:33 confirming those once outlandish-sounding conspiracy theories that had

44:37 persisted in Japan relating to the disappearances for decades.

44:41 These abductions were an organized program under

44:43 the reign of Kim Il-sung in North Korea,

44:46 the grandfather of the current country's ruler Kim Jong-un,

44:49 and the original founder of the Kim dynasty who personally ruled

44:53 for nearly 46 years across the second half of the 20th century.

44:58 To this date, Kim Il-sung is still officially regarded

45:01 by North Korea's legal system to be the country's eternal president,

45:06 even though he died decades ago back in 1994.

45:09 [music] He is still heralded as nearly a god in the country along

45:13 with his son and grandson who have

45:15 both taken over the country's rule following him.

45:18 And I think that understanding him and how

45:20 he molded North Korea into the bizarre necro-hereditary dictatorship

45:25 that is today is a major lesson in what

45:27 can happen with truly unchecked power in the modern world.

45:31 And so, I made an entire new documentary exploring the dark

45:35 world and life of Kim Il-sung and the most outlandish

45:39 things he did while ruling North Korea for decades

45:42 in my brand new original documentary series that I'm calling Mad Kings,

45:47 which will take deeper dives into the terrible personal lives

45:50 and erratic policy decisions of recent megalomaniacal and eccentric dictators.

45:56 But because of the inherently violent details surrounding Kim Il-sung,

46:01 including details and depictions of multiple acts of terrorism

46:04 that he personally ordered across the 1980s and '90s,

46:08 my documentary investigating his reign would never work

46:11 on YouTube because it would instantly become demonetized and age-restricted,

46:16 which means that YouTube's algorithm that's

46:18 based around showing you ads would never

46:20 actually be incentivized to show the video to you or to promote it.

46:24 I deal with very large numbers of my videos

46:26 on YouTube getting demonetized and age-restricted as they already are,

46:30 including my recent video from just last month

46:33 covering the ongoing events taking place in Darfur.

46:36 And that's why I'm uploading all of my documentaries and Mad Kings,

46:39 including this one on Kim Il-sung, exclusively to Nebula instead.

46:45 And why signing up to Nebula is the absolute best

46:48 thing that you can do to support me and my channel.

46:51 And there's never been a better time to sign up because you can

46:54 now get 50% off of the annual subscription for just $30 entire year.

47:00 A perfect gift that you can also give

47:03 to someone else in the lead up to Christmas.

47:05 And there's plenty of new content for you to watch right now.

47:09 There's Scav, a new documentary series by the Jetlag

47:11 team that follows the world's largest scavenger hunt.

47:14 There's multiple new exclusive video essays by Lindsay Ellis.

47:18 And a new short film by Patrick Willems called

47:20 The Dinner Plan that features Griffin Newman and Zack Cherry.

47:23 And of course, Nebula is also still home to some of the best

47:27 curated and informative documentaries that are available on the internet today.

47:31 There's Bobby Broccoli's 17 Pages documentary covering one

47:34 of the largest scientific controversies of the 20th century.

47:47 And of course, my own modern conflict

47:49 series covering dozens and dozens of modern wars,

47:53 battles, and conflicts with plenty more originals

47:59 [music] And if you're not sure about Nebula or have

48:02 been sitting on the fence about it for a while,

48:04 you should know that we're now offering a 3-day free trial.

48:07 And we dare you to try and watch all of our exclusive content in those 3 days.

48:12 I personally treat Nebula as my own sanctuary away from the noise

48:16 of algorithmically driven sites like YouTube and other social media,

48:20 both as a creator and as a viewer.

48:22 There's no AI bots and no AI generated slop clogging up your feed here.

48:30 with and that enables us to only work with the best,

48:34 creators who truly love and take pride in everything they do.

48:38 So, if you want to support me and hundreds

48:41 of other independent creators who still value our craft and get
