@AK98 that's not how mafia Japan works. If you quit before 3 years are up, future employers will assume there's something very wrong with you. If there's a meeting, you're generally expected to be there an hour early, and people will treat you like you're late if you aren't. It's a very different culture.
Japan's work culture is pretty fucked up. You would think that with the amount of time they spend at work they would be getting more done, but studies on the subject have shown that they really aren't any more productive than people working a fraction of the number of hours. So what are they even doing?
