A Chinese in Tokyo, the most prosperous area of Japan's capital and Kabukicho district of Tokyo Metropolitan, personally experienced the survival status of various people around him. What is unbelievable is that in this era, in Japan, a developed country which claims to be democratic and respect human rights, there openly exists a kingdom strictly divided into different spheres of influence under the domination of various black社会组织ations. They lure, abduct and coerce young women from all over the world, ready to expand their own territory at any time, highly alert to being swallowed up by other gangs, and when necessary, they will not hesitate to fight and kill each other. This documentary literature truly reflects a scene of contemporary Japanese society that is completely at odds with modern civilization, a scene that can make readers feel shocked and sad. Perhaps this scene can serve as a certain warning to those who think that Japan is a paradise for making money.
