Joseph Keenan is outgoing and easy to make friends. On the surface, they often talk and laugh, act freely and generously, but in fact, they know how to avoid the important and play some "tricks" when necessary, which is a style of politicians.

1945 16 February 16, the Soviet union, the United States and Britain held a meeting in Moscow and decided to set up an international military tribunal for the far east, which was composed of eleven countries including the United States, China, Britain, the Soviet union, France, Australia, Canada, New Zealand, the Netherlands, India and the Philippines. According to the Charter of the Far East International Military Tribunal, the Tribunal has the right to try Japanese Class A war criminals who have committed the following three crimes: the crime of undermining peace; War crimes; Crime against humanity. Joseph Keenan was appointed as the chief prosecutor of the Far East International Military Tribunal and the director of the International Procuratorate of the Allied Headquarters.

Before the Tokyo trial, Ji Nan, who had just arrived in Tokyo, publicly stated that he would use his experience in the Ministry of Justice to confront Japanese war criminals and subdue these robbers. In court, Ji Nan is eloquent, eloquent and experienced. Sometimes I like to make long speeches, use big articles and quote "famous sayings" (such as Roosevelt, etc. Because of my arrogance, I sometimes have a bad temper. Because of his strong, resolute and overbearing attitude, people nicknamed him "devil's prosecutor".

Under the strong impetus of Jinan, the international procuratorial organs went all out to interrogate war criminals and collect evidence. Prosecutors divided their work and shared the procuratorial work in various stages, such as Japan's preparations for war, the Manchuria Incident in China, Japan's all-round invasion of China and the Pacific War.

At 8: 42 am on May 3, 1946, the car escorting Japanese war criminals came to the gate of the Far East International Military Tribunal. In the view of the reporter of Asahi Shimbun, "this group of war criminals is like a team in a hurry."

Sir Webb, President of the Far East International Military Tribunal, read the opening speech, and Chief Prosecutor Ji Nan began to read the indictment. A Japanese reporter once made a metaphor on the first day of the court session: "Every scene is like watching Shakespeare's famous plays!"
