China is a big country with a history of 5,000 years, and in this long period of time, many unique characteristic cultures have been formed, of which the surname culture is the oldest and closely related to everyone. In China, surnames are generally given by family ancestors, and names are given by parents who give birth to themselves, which is a sign that accompanies a person's life. But sometimes foreign people come to China, and for convenience, they will give themselves a Chinese name, including during the War of Resistance Against Japan.

On September 18, 1931, under the arrangement of the Japanese Kwantung Army, the railway "garrison" blew up the tracks of the South Manchuria Railway near Wicker Lake in Shenyang, and planted bribes on the Chinese army. The Japanese army used this as an excuse to launch the famous "918 Incident". This was the beginning of the Fourteen-Year War of Resistance Against Japan.
After that, Japan established a puppet regime in the puppet state of Manchukuo in northeast China, and a large number of Japanese troops poured into Chinese territory. At that time, out of turmoil in our country, aggressors from various countries poured into China one after another. After some foreigners come to China, in order to facilitate the integration of local convenience work, they will give themselves a Chinese name.
Among them was a Japanese secret service officer named Iso kuniaki. We know that China's 14-year War of Resistance actually began on September 18, 1931. But this didn't happen suddenly, it was actually a decision made by the Japanese military for a long time.
As early as September 1912, the "advance team" of the Japanese invasion of China came to China. Koiso Kuniaki held the position of staff officer of the Kwantung Bureau's Army Staff. His main task was to collect important geographical records of soldiers in the Liaodong Peninsula and Lushun area, that is, important information such as geographical environment, customs and human feelings.
In fact, a lot of important intelligence was collected by Koiso Kuniaki, who did not bother to gather intelligence at that time. He wore a long shirt and coat from the northeast region, pretended to be a Chinese and ran in North China and Manchuria for two years. In order to better integrate into the local area, he also gave himself a "fashionable" Chinese name.
Koiso Kuniaki's Chinese name is Katsuyama Sugi, which is still quite good from a literal point of view, but it is more difficult to read. In fact, when Koiso Kuniaki took this name, it was well thought out. After all, Japan's name jokes about Chinese are not once or twice.
For example, there was once a Japanese man who was pro-Male Yamamoto, and after he arrived in China, in order to better integrate into the local area, he actually changed his name to "Fan Jian", although the meaning of the name is very good, but maybe he does not understand the true meaning of it at all!
After Koiso Kuniaki gained Chinese name, he disguised himself as a Chinese began to carry out espionage operations in the northeast of China. A complete topographic and geological map of the Northeast was drawn. And the people in northeast China are thoroughly understood.
June 19, 1931. The Japanese General Staff Headquarters formulated the Outline of the Program for Resolving the Manchu-Mongolian Question. Koiso Kuniaki, in his capacity as director of the Military Affairs Bureau, studied and deliberated on this outline. It also put forward important proposals for strengthening Japan's rule over Northeast China.
In 1945, The fascist war criminal state of Japan announced its unconditional surrender. After Japan's defeat, Koiso Kuniaki could not face the criticism of his countrymen and had to resign and return to his hometown. In the end, he was arrested by local farmers and sent to the national court and designated as a Class A war criminal suspect. Sentenced to life imprisonment, he eventually fell ill and died a year later in Sugamo Prison, ending his sinful life.
