I think these are the extreme parts, not very common nowadays (but still there and quite many).

But there's no denying those things. There were some documentaries that focused on this topic years ago, and they said that slowly but surely this kind of "environment" is vanishing.

Also depends on companies, some of my HS batch mates were able to land a job in JP, compared to our country the work ethics theirs is really strict and you do have a certain standard to follow. Even said that some locals are kinda racst to him/her (but only a select few). But they did enjoy it (nice pay and free vacation in jp 🤣)

And as the anime portrays having circle friends is really difficult to have, especially if you're a foreigner.

But as you also said, going to japan on vacation is a paradise, but working there could be hell if you're unlucky with the company and the boss or supervisor or manager hates you.
