Due to the peculiarities of intelligence work, the information of most spy fighters is strictly confidential, and it is often difficult for outsiders to know, until many years after the end of the war, the true identity and activities of these people will be declassified and made public.
However, there are also many very special examples, such as the Takeda Takeo we are going to introduce today.

Search for "Takeda Takeshio" on the Internet, there will be details of him: wang Yixiong, formerly known as Wang Yixiong, was born on April 28, 1904 in Lushun, Liaoning, China, the father's name is Wang Chunyang, the mother's name is Kikuchi Sadako, graduated from the Tokyo Army Non-Commissioned Officer School.
Such a resume seems complete enough, so why say that his identity is still very mysterious?
First of all, from his resume.
Takingda spent 14 years in the Japanese army from 1922, during which time he served as a senior staff officer, a brigade commander, and a section chief of the Kwantung Army. Judging from his position, he was an important figure within the Kwantung Army that could not be ignored, but in fact, he himself had joined the Communist Party early on, was a veteran international communist fighter, worked in the intelligence and reconnaissance departments of China and the Soviet Union, and even made great contributions to the neutrality of the operation to crush the assassination of Stalin.
Some historians believe that after the arrest and sacrifice of Sorge, the "god of spies" of the Soviet Union, Takeda Takeda, code-named "Terekin", was the most important ace spy of the Soviet Union in the Far East.
However, it was such an outstanding spy who mysteriously disappeared in February 1945 without any news.
It was not until the period of the War to Resist US Aggression and Aid Korea that Takeda Tooko infiltrated the intelligence department of the US military as a "Shumit" and provided strong support for our army's victory in the War to Resist US Aggression and Aid Korea.
After the end of the War to Resist US Aggression and Aid Korea, it is reasonable to say that it should be possible to restore one's identity, right? After all, the war was over, but at this time, Takeda Tooko mysteriously disappeared again, and has never appeared again to this day.
It was not until November 7, 1964, that the Soviet side suddenly announced that Takeda was posthumously awarded the honorary title of "Hero of the Soviet Union". Such a move is undoubtedly telling the world that Takeda Ishio is already dead!
So why did the news of his death not be announced until many years later? Why is it only the Soviet Union that recognizes it? This is doubtful.
Then, let's look at the biggest controversy about Takeda Tsutomu – is there such a character?
In fact, the information we can learn at present is basically "said", and there is no historical data available for reference to prove it, and many historians have gone through the military materials of the three countries during World War II, but have never found any records about him. If china and the Soviet Union are for secrecy, then what is the reason why the Japanese side chose to conceal it? Is it because of the fear of humiliating people by saying it?
Thus, although takeda's deeds were once well documented, a growing number of historians believed that takeda was more likely to be fictionalized.
Based on this, some people also cite a lot of evidence: the resume says that Takeda Tooko served as the head of the Chinese section of the Japanese General Staff Headquarters from June 1936 to July 1937, but the head of the Chinese section during this period was Nagatsu Sasuke, in other words, one of the two must be false.
In addition, the resume says that he served as the brigade commander of the Japanese 17th Division, but the reality is that the 17th Division has no brigade unit at all, and naturally there will be no brigade commander.
Finally, from the perspective of blood relations, the Japanese during World War II implemented a patrilineal blood system, that is, as long as the father was not Japanese, he could not join the Japanese nationality, let alone join the Japanese army, unless it was a very special existence, such as the Korean Crown Prince Lee Yan. Obviously, Takeda does not have this particularity.
Combining the above analysis, we can conclude that "Takeda Takeshi does not exist".
The controversy over whether Takeda really exists may continue, but whether he is true or not, the stories on him sound legendary enough.
