As someone living in Japan (and working for a mostly reasonable Japanese-owned and operated company), I'm often a bit annoyed by the people confidently spouting second-hand Reddit knowledge that all Japanese workers are in situations like this (e.g. returning home from work at midnight, unable to quit, etc). If every company was a black company, they probably wouldn't have a word for it!
That said, it is far more common to work overtime here than in my home country and I'm puzzled by how many Japanese people I encounter who are like "Yeah working too much overtime is bad and people shouldn't have to do it. I don't like having to work overtime. Also I work multiple hours of overtime every day and have no plans to do anything to change that, it is what it is." When I inquire further, it doesn't seem like they CAN'T change jobs, more like inertia and passivity (and perhaps a sense that it's too hard/unlikely to find a significantly better situation). Going through the job search and interviewing process again is apparently a higher immediate mental barrier than the annoyance of working overtime every day.
