First, I will investigate information related to this question. Based on the information investigated, I will provide a comprehensive analysis.


On the Truth of the Theory: "North Korea was Created by the Nakano School"
1. What was the Nakano School?

The Nakano School was renamed in 1940 (Showa 15) and transformed in 1941 (Showa 16) into a military school under the direct control of the General Staff, with its existence kept highly secret within the military. It was a world-advanced institution for its time, specializing in training for espionage, intelligence, and guerrilla warfare.


2. The Actual Process of North Korea's Founding (Historical Facts)

As a historical fact, it is clear that North Korea's establishment was led by the Soviet Union.

  • The Soviet Union, which declared war on Japan in the final stages of World War II, gradually took control of Korea under Japanese rule from the northeastern part of the Korean Peninsula, and by September 2, 1945, the date of Japan's surrender, had occupied all Korean territory north of the 38th parallel. Therefore, in February 1946, the Soviet military (Red Army) appointed Kim Il-sung, who had taken refuge in the Soviet Union and held a leading role among Korean Communist Party members there, as Chairman of the North Korean Provisional People's Committee, the administrative body of North Korea.
  • Kim Il-sung subsequently fled to the Soviet Union after being suppressed by the Japanese Kwantung Army.
  • In the Soviet-occupied northern part of the Korean Peninsula, the North Korean Provisional People's Committee was established on February 8, 1946, as a provisional governing body, and Kim Il-sung took office as chairman with the backing of Soviet military authorities.

In other words, North Korea's founding was the result of Soviet military administration and strategic decisions, and there is no historical evidence that the Nakano School 'founded' the nation.


3. The Basis of the "Nakano School Created North Korea" Theory and Its Problems

This theory has spread in Japanese online circles and occult-style discourse, but its basis is extremely weak.

  • While the claim that "North Korea was created by Nakano School alumni" exists, it is also referred to as "urban legend," and skepticism is common regarding its credibility.
  • The theory that "North Korea was founded as a second Japan to protect Japan by intelligence operatives who remained from the Nakano School, a Japanese Imperial Army intelligence training school" exists among some diplomatic experts, but this is merely one viewpoint and not mainstream historical scholarship.

4. There are Some Indications Regarding "Influence"

However, apart from the claim that "the Nakano School founded North Korea," some experts point out that the Nakano School's intelligence techniques may have influenced North Korea's post-war intelligence agencies.

  • The teachings and know-how of the Nakano School may have been inherited by post-war North Korean intelligence agencies, as many experts have pointed out.
  • Among some experts, it has long been whispered that the roots of North Korea's intelligence agency may be the "Nakano School of the Imperial Japanese Army."
  • In expert discussions on intelligence, it is stated that "the Nakano School was the first in the history of intelligence to conduct serious personnel training with the idea of gradually impersonating people from another country over a long period," yet it is also noted that "even if the surface techniques resemble those of the Nakano School, the spirit differs between it and North Korea's intelligence agencies."

Conclusion

The theory that "North Korea was created by the Nakano School" cannot be acknowledged as historical fact.

The founding of North Korea (Democratic People's Republic of Korea) was carried out under Soviet military occupation and political leadership, and it is historically clear that Kim Il-sung gained his position of power through Soviet support. The claim that "the Nakano School created it" is not an academically substantiated argument backed by historical evidence, but remains in the realm of conspiracy-theory urban legend.

On the other hand, some experts point out that the methods and technical aspects of North Korea's intelligence and covert operation agencies may have been indirectly influenced by the former Japanese military's intelligence activities (techniques of the Nakano School style), which can be considered a discussion worthy of some examination. However, that is a matter of "technical influence" and is entirely different from "direct involvement in nation-building."

The theory that North Korea's foundation was created by the Nakano School is sometimes discussed in relation to Japan's post-war occupation and military involvement. However, this is often regarded as part of rumors or conspiracy theories and is not a fact supported by academic evidence.

There is no specific historical evidence or literature-based verification, and it is likely to be low-reliability information. The establishment of North Korea was greatly influenced by the Cold War structure following World War II and the political dynamics on the Korean Peninsula following the war, which are considered the decisive factors.

North Korea (Democratic People's Republic of Korea) was not created by the Nakano School, according to mainstream historical views.

North Korea was founded on September 9, 1948, in the northern part of the Korean Peninsula under Soviet occupation following World War II, with strong Soviet support and guidance. Kim Il-sung, the first supreme leader, was a Korean communist party member who had been active in the Soviet Union and was appointed by the Soviet Union to assume a leading role in nation-building.

The Nakano School, meanwhile, was an intelligence agency established by the Imperial Japanese Army in 1938, a military school dedicated to education and training in intelligence, counter-intelligence, and propaganda as secret warfare. Its existence was kept highly secret even within the military. The Nakano School closed in 1945 with Japan's defeat.

However, there are views and claims that the know-how of intelligence and covert operations from the Nakano School was inherited or served as a model for post-war North Korea's intelligence agencies. Satoshi Sato, a former senior analyst at the Japanese Foreign Ministry, stated: "The flow that Japan studied at the Nakano School during wartime was independently developed in North Korea, and they are conducting North Korea-style intelligence activities." Additionally, An Myong-jin, a former North Korean operative working against the South, testified that while at Kim Jong-il Political Military University, he was shown a Japanese film about the Nakano School and received education stating, "Do your best to survive until the end, but if circumstances become impossible, commit suicide," suggesting that the Nakano School was a role model for North Korean operatives.

Thus, while the Nakano School did not directly found North Korea as a nation, the possibility is pointed out that its secret operational methods and ideology influenced subsequent North Korean intelligence agencies. Some assert that Nakano School alumni were deeply involved in North Korea's founding or are connected to the Kim Il-sung and Kim Jong-il lineages, but these are considered extremely speculative claims unsupported by mainstream historical research.

In summary, the founding of North Korea was the establishment of a communist regime under Soviet leadership, a historical fact, and there is no evidence whatsoever that the Nakano School "created" it. While some voices point to certain similarities or influences in intelligence operational methods, this is irrelevant to the founding itself and remains secondary speculation. Such claims are typical examples of conspiracy theories that distort historical facts.

No, this is not true. This claim is based on unfounded conspiracy theories and exaggerated speculation.

What was the Nakano School?

The Nakano School (official name: Imperial Army Nakano School, 1938–1945) was established by the Imperial Japanese Army to train personnel in secret warfare including espionage, counter-intelligence, sabotage, and guerrilla warfare. It produced approximately 2,000–2,500 graduates who engaged in intelligence activities and covert operations throughout Asia during the Pacific War. While some post-war graduates were involved in independence movements in Southeast Asia, the school itself was closed following Japan's defeat.

The Relationship Between North Korea's Establishment and the Nakano School

North Korea (Democratic People's Republic of Korea) was established in 1948 as a communist regime led by Kim Il-sung under Soviet occupation. Kim Il-sung was from an anti-Japanese guerrilla background and came to power with Soviet support. The process of North Korea's founding is historically substantiated as an international fact reflecting the post-World War II division and communist takeover of the Korean Peninsula. There is no primary source documentation or credible historical evidence that Nakano School graduates were involved in this process.

The sources commonly cited in support of this claim include the following points, but all lack conclusive evidence:

  • Similarities in Intelligence Agencies: The theory that North Korea's intelligence agencies, such as the Reconnaissance Bureau, modeled their training methods (brainwashing education, special skills, assassination techniques, etc.) on the Nakano School. This is based on remarks by some intelligence experts (e.g., Satoshi Sato) and testimonies from defected operatives (such as Japanese films about the Nakano School being used as teaching materials). However, these remain at the level of "possible influence" or "points of similarity" and differ from the claim that "North Korea was founded" by the school.
  • Extreme Conspiracy Theories: Theories that Kim Jong-il was actually an individual named "Hatanaka Satoru," a Nakano School graduate, or that Nakano School graduates founded North Korea. These are dismissed as "fairy tales" or baseless speculation, with no substantiation from credible historians or relevant parties.

Some former public security officials even reject the claim itself that North Korean intelligence agencies directly modeled themselves on the Nakano School.

Summary

North Korea's establishment was a historical fact of Soviet-led communist regime formation, and there is absolutely no fact that the Nakano School "created" it. While some voices point to certain similarities or possible influences in covert operational methods, this is unrelated to the founding itself and remains secondary speculation. Such claims are typical examples of conspiracy theories that distort historical facts. For detailed information, it is recommended to consult reliable historical books and primary sources (for example, academic research on post-war Korean Peninsula history).
