It sounds funny to visit a prison in Japan, but when I think about this trip after all the visits, I realize that the prison, as such a national violence institution, can show its historical evolution and current reality so vividly. With the investment of 3D audio-visual, experience projects and wax figures, it is rare. How prisoners bathe, how manic prisoners are restrained, three meals a day, working time and content, prison breakers and so on are clearly explained, and Japan's consistent people-oriented design concept is not penalized. If you drive to a prison by yourself, you have to add the Internet to the navigation. Otherwise, you will be navigated to a prison not far away from the internet. In fact, I went to a real prison, and later to the museum, I found that the gate was exactly the same. Tickets for adults are 1080 yuan. You may need a map in Chinese when you buy tickets. The map will show routes and points of view, highlights are introduced in detail, and historical relics are clearly marked. After previewing, it will be easy to understand and understand the development process of Hokkaido according to the context.
