Any court system that assumes guilt is a bullshit one. The Japanese legal system seems to be designed to get people to admit guilt so the process ends quickly. That's a garbage-fire of a legal system.

It would be more fair to say "the Japanese court system presumes guilt and treats everyone like inhuman garbage, even rich folk."

There was a fun incident in the UN where an ambassador from Japan made a remark that Japan's justice system was modern and exemplary. Everyone in the room just laughed at him. (He got upset, and told everyone to shut up, and then got fired for his outburst.) https://www.youtube.com/watch?v=WYfHWsWJhtg
