Harsh Working Environment in Japan

Japan is well known for harsh working environment. I guarantee that it is true because I am Japanese and I worked in harsh working environment in decades ago. Worked all night for three days. I was depressed. It was natural. In Japan, a lot of people suffer because of job, harassment and suicide. I think we change this ridiculous environment. Probably, in the world, a lot of people face similar situation. Teach me your work environment.
