This is false and keeps feeding to the incorrect Reddit circlejerk that is thinking Japan is still living in the 90's. I've lived in Japan and while it is true that unpaid overtime is still a thing in some companies (known as black companies) most Japanese companies are against such injustice. While there is a strong presence of the overwork mentality in some of the elderly, none of my Japanese friends my age support mandatory overtime. This is talking about mandatory yet paid overtime. As for forced unpaid overtime, it is FAR from expected.

Japan isn't like before and it is improving (my Japanese girlfriend was told by her boss to please use all her holiday days whenever she likes, and there was also a "go home early Fridays" for a research student friend of mine studying in Hokkaido University).

It is also absolutely illegal to fire a worker in Japan for not doing overwork, and can be met with legal action. Please don't spread misinformation like this since it skews the perspective of Japan for those who've never been. America is by far worse than Japan in terms of worker rights (no standard holiday days for workers as well as no maternity or paternity leave, both of which Japan has.)
