What Happens in Know Your Enemy: Japan: Full Plot Summary

The whole story of Know Your Enemy: Japan (1945) explained, from the opening scene to the final frame: every key event, every twist and what it all adds up to. Read it as a quick recap before the sequel, to check a scene you missed, or to finally understand what really happened.

The film opens with a statement emphasizing that Japanese Americans valiantly fought for the United States, standing for core values like "freedom" and "liberty". It clarifies that the subsequent content does not portray all Japanese people as aggressors but rather focuses specifically on Japanese natives who are depicted as the aggressors. The narrative then dives into the lives of members of the Imperial Japanese Army, primarily highlighting their appearance and diet rather than their military tactics or strategies. This approach suggests a focus on the uniformity and sameness among soldiers, describing them as "as alike as photographic prints off the same negative," implying a lack of individual distinction.

A significant part of the film discusses the devotion of Japanese soldiers to Emperor Hirohito, portraying him as the divine figure they entrust with immense powers. The narration states that the Japanese revere Hirohito similarly to how Western nations might view their leaders, claiming that "entrusting to one man the powers of the President of the United States, the Prime Minister of Great Britain, the Premier of Soviet Russia" resonates with their concept of Hirohito. The film refers to him as the "God-Emperor," emphasizing his divine status in the eyes of his people.

Further, it explains the divinity of Hirohito, asserting that this divine origin is shared with the entire Japanese nation, thus reinforcing a sense of national unity and divine right. The film then discusses Shinto, Japan's native religion, describing it as a "quaint religion" that "until 1870 was just a quaint custom", until a militaristic and expansionist doctrine was woven into it. This doctrine, rooted in the beliefs of Jimmu, the first emperor, promoted the idea of "Hakkō Ichiu" — a concept meaning "all the world under one roof." The film portrays this as a fanatical pursuit for world domination, linked to the divine authority given to the emperor.

The Yasukuni Shrine, a significant Shinto shrine where all of Japan's war dead are enshrined, is highlighted as a sacred site from which the spirits of fallen soldiers will return. The narration suggests that if you are Japanese, these beliefs are ingrained, but it prompts viewers to wonder about the true nature of Japan from a geographical, anthropological,, and historical perspective.

The film then counterbalances the idea of "pure divine blood" in Japanese people with the notion that it is merely a "plasma cocktail", hinting at questions about racial purity. It provides a historical overview, claiming that power was historically held by daimyōs and samurai, with the Emperor wielding little real political influence. The samurai, with their Bushido code, are condemned for sanctioning treachery and double dealing, which the film suggests were perceived as an art form.

A critique of Western influence follows, noting the expulsion of Christianity and the isolation of Japan for 200 years, as reactions against Western teachings of peace and equality—elements portrayed as threatening to Japan's traditional ways. The Western advances during the Age of Enlightenment are contrasted with Japan's stagnant isolation until the arrival of Commodore Perry in 1853, which is presented as the breakpoint for modernization.

During the Meiji Restoration, the film notes the Westernization of Japan, claiming that it was used by warlords to further their own ambitions, and describes the elimination of the Shogunate in 1868, elevating the Emperor as a symbolic figurehead. However, it claims real power remained with the warriors who guided the Emperor's policies. The Tanaka Memorial, a questioned forgery allegedly outlining Japan’s plans for world conquest, is invoked as evidence of Japan's true ambitions.

Throughout, warlords are depicted as maintaining power by rejecting Western moral principles, instead controlling the flow of information to the Japanese people, filtering and altering it to serve their interests. The film emphasizes that despite modemization, most Japanese continued living and working in medieval-style conditions, and urban workers still led lifestyles reminiscent of ages past.

The expansionist and militaristic actions of Japan during World War II are explained as an extension of the warlords’ control over society. The film concludes with a reflection on Japan's wartime circumstances in 1945, implying that the warlords' influence was the root cause of Japan's aggressive behavior. The narrative paints a picture of a nation caught between divine destiny and traditional power structures, which ultimately led to its militaristic pursuits during the war.

Overall, this documentary-style film presents a complex view of Japan’s historical evolution, emphasizing divinity, tradition, and wartime expansion, making it clear that the real power was often hidden behind traditional institutions and belief systems that fueled Japan’s aggressive expansion during the early 20th century.

The questions people ask most about Know Your Enemy: Japan (1945): what happens in the confusing scenes, why the characters do what they do, the twists, hidden details and what the ending means. Each answer contains spoilers.

Q1

Why does the film distinguish between Japanese Americans and Japanese natives?

The film opens by acknowledging that Japanese Americans valiantly fought for the United States and uphold American values like freedom and liberty. This distinction is made to clarify that not all Japanese people are portrayed as aggressors, the film focuses specifically on Japanese natives who are depicted as the enemy in the context of World War II. This framing was intended to address potential concerns about loyalty and to direct anti-Japanese sentiment toward the enemy nation rather than Japanese American citizens.

Foreshadowing: The opening statement sets up the film's critical approach toward Japanese military leadership rather than the broader Japanese population.

  • japanese americans
  • japanese natives
  • distinction
  • world war 2
  • enemy
Q2

What does the film say about Emperor Hirohito?

The film portrays Emperor Hirohito as a divine figure, referring to him as the 'God-Emperor.' It describes how Japanese soldiers revere Hirohito by comparing his authority to combining the powers of the U.S. President, British Prime Minister, and Soviet Premier into one person. The film emphasizes that Hirohito's divine status is shared with the entire Japanese nation, reinforcing the concept of divine right and national unity.

Foreshadowing: This divine portrayal establishes the ideological foundation that the film claims motivated Japanese expansionism.

  • emperor hirohito
  • god-emperor
  • divine
  • reverence
  • emperor worship
Q3

What is the Tanaka Memorial and why does the film reference it?

The Tanaka Memorial is a document allegedly written by Japanese Prime Minister Tanaka Giichi in 1927, outlining plans for world conquest. The film references it as Japan's equivalent to Hitler's Mein Kampf, presenting it as evidence of Japan's secret imperial ambitions. However, historians today consider the Tanaka Memorial to be a forgery, likely manufactured to support wartime propaganda efforts.

Foreshadowing: The document is presented as the foundational blueprint for Japan's expansionist policies.

  • tanaka memorial
  • forgery
  • world conquest
  • warlords
  • expansionism
Q4

What is Hakkō Ichiu according to the film?

Hakkō Ichiu is a Japanese concept meaning 'all the world under one roof.' The film explains that this doctrine was woven into Shinto after 1870 as part of Japan's militaristic expansion. It portrays Hakkō Ichiu as a fanatical pursuit for world domination, linking the divine authority given to the emperor with imperial ambitions that the film claims drove Japan's aggressive expansion during World War II.

Foreshadowing: This concept serves as the ideological basis for Japan's wartime expansion explained throughout the film.

  • hakko ichiu
  • world domination
  • shinto
  • emperor
  • expansionism
Q5

How does the film explain Japan's militarism according to the film?

The film attributes Japan's militarism and expansionism to the control exerted by warlords and military leaders over Japanese society. It claims that despite the Meiji Restoration elevating the emperor as a symbolic figurehead in 1868, real power remained with warlords who guided policies while rejecting Western moral principles. The film portrays these warlords as manipulating modernization and information to serve their imperial ambitions.

Foreshadowing: The narrative traces this power structure back to the historical dominance of daimyōs and samurai.

  • warlords
  • militarism
  • power
  • meiji restoration
  • expansionism
Q6

Why does the film focus on soldiers' appearance and diet?

The film depicts Imperial Japanese Army soldiers focusing on their appearance and diet rather than military tactics or strategies. This approach emphasizes uniformity and sameness among soldiers, describing them as 'as alike as photographic prints off the same negative.' The film uses this to suggest a lack of individual distinction among Japanese soldiers, portraying them as a homogeneous, disciplined force operating under collective ideology.

Foreshadowing: This emphasis on uniformity connects to the film's broader theme of collective devotion to the emperor.

  • imperial japanese army
  • soldiers
  • uniformity
  • appearance
  • diet
Q7

What is Shinto according to the film?

The film describes Shinto as Japan's native religion, calling it a 'quaint religion' that until 1870 was merely a custom. It explains that after 1870, a militaristic and expansionist doctrine was woven into Shinto, transforming it from a peaceful faith into a tool for imperial expansion. The Yasukuni Shrine, where Japan's war dead are enshrined, is highlighted as a sacred site reinforcing nationalist sentiments.

Foreshadowing: This transformation of Shinto is presented as key to understanding Japan's wartime ideology.

  • shinto
  • religion
  • yasukuni shrine
  • nationalism
  • 1870
Q8

What does the film say about the samurai and Bushido code?

The film portrays the Emperor as historically having little real power, with political authority held by daimyōs and samurai. It criticizes the samurai class and their Bushido code for sanctioning treachery and double-dealing, suggesting these practices were perceived as an art form in Japanese culture. This portrayal connects the historical samurai traditions to what the film frames as inherent militaristic tendencies in Japanese society.

Foreshadowing: This criticism extends to the modern warlords the film identifies as controlling Japan.

  • samurai
  • bushido
  • daimyo
  • treachery
  • warrior class
Q9

What was Commodore Perry's role in Japan's history according to the film?

The film presents Commodore Perry's arrival in Japan in 1853 as a critical breakpoint. It contrasts the scientific and artistic advances of the West during the Age of Enlightenment with Japan's stagnant isolation period. Perry's forced opening of Japan is portrayed as the catalyst that began Japan's modernization, which the film claims was subsequently exploited by warlords for their own ambitions.

Foreshadowing: This sets up the film's explanation of how Japan was manipulated into modernization without adopting Western values.

  • commodore perry
  • 1853
  • isolation
  • modernization
  • western influence
Q10

What does the film say about the Meiji Restoration and emperor's power?

The film explains that during the Meiji Restoration in 1868, the shogunate was eliminated and the Emperor was elevated as a national symbol. However, it claims that real power remained with the warriors and warlords who guided the Emperor's policies. The film portrays Hirohito as a figurehead lacking autonomy, with the emperor's divine status serving as a tool for the warlords to consolidate control over the Japanese people.

Foreshadowing: This establishes the power structure that the film argues led to Japan's wartime aggression.

  • meiji restoration
  • emperor
  • figurehead
  • warlords
  • 1868
Q11

How does the film describe control of information in Japan?

The film emphasizes that warlords maintained power by controlling information flow to the Japanese people, filtering and altering it to serve their interests. It claims that despite modernization, most Japanese continued living and working in medieval-style conditions, and urban workers still led lifestyles reminiscent of ages past. This creates a picture of a society deliberately kept ignorant and technologically backward while being led toward imperial expansion.

Foreshadowing: This control of information is presented as the mechanism that allowed warlords to pursue aggressive policies.

  • information control
  • warlords
  • propaganda
  • medieval conditions
  • manipulation
Q12

What is the film's overall perspective on Japan in 1945?

The film concludes by illustrating Japan's dire wartime circumstances in 1945, portraying the devastation and consequences of military expansionism. It frames Japan's aggressive behavior as a direct result of entrenched power structures, the warlords' influence, that manipulated religious beliefs, historical traditions, and national identity. The ending is bleak, suggesting these power structures led Japan to destruction without offering resolution or hope.
