How many Japanese immigrants from World War II came to China?

Certainly not less than 3 million Japanese nationals. Since the invasion of the three northeastern provinces, the Japanese invasion plan has become increasingly obvious. Japan fostered Manchuria, annexed various national cultures of China with Japan, and brought a large number of Japanese expatriates to live in China, so that their descendants were of Japanese descent. In addition, a large number of young orphans in China and mixed-race children in China and Japan will be given closed education to integrate their thoughts into Japanese culture. In fact, most of the ace spies who appeared in the Japanese secret service were Japanese and mixed-race Chinese and Japanese. Not only that, the soldiers of the Japanese army are also mixed with China people of many other nationalities.

Takeda Yoshio, who is called the first ace spy in World War II, is actually a native of China. He was an orphan in China and was adopted by a pair of Japanese nationals who were infertile at an early stage. Later, they were taken back to Japan, only saying that they were born, and no one went to investigate. Later, he was named Takeda Yoshio, enrolled in Imperial Military Academy in Tokyo, and became the best student of Kenya Hara and Sakamoto Seijiro. Less than 30 years old, he became the youngest major general of the Japanese army. But in fact, he already knew that he was from China. After the development of Zhou Enlai, he secretly became an underground spy of the Soviet Union.
