South Korea has the term "death by loneliness," many apparently don't have one single person that is some kind of friend. They are cremated alone and now they send in some buddhists or whatever to show they had value. The work philosophy is absolutely horrible there imo, disgusting. Lots of suicides due to issues at work or losing "honor." Vacations are hudreds of people crammed into a little pool, what a nightmare

I was in Japan last year for about a month. The second night I was in Tokyo while waiting at a train station, there was an announcement stating that there would be delays in the timetable due to an "accident" on one of the train lines. I later found out that "Accident" is the code word for suicide. A popular method of suicide for an overworked salary man or office lady in a Japanese city is to throw themselves in the path of an oncoming train.
Their work culture is fucking horrendous. Officially, the work day is 8 hours, but in reality people are expected to stay back at the office anywhere from 2 to 4 hours longer than that, even if there's no additional work to be done, in which case it usually involves people sitting at their computers opening and closing emails, sweeping imaginary rubbish, or something equally pointless and unproductive. If they don't stay back, it can hurt their prospects for promotion, pay rises, lead referrals if they work in commission type jobs, etc. On top of that, if you take into account commute times (many travel from outside the city to and from work) which can be 1 or 2 hours each way (sometimes longer), they're spending almost all of their time away from home, which affects family/home life, birth rates, etc. Catching a train on a week night, you see people slumped over in their seats sleeping, some occasionally falling onto the floor. I've read recently that Tokyo is introducing a 4 day work week for public servants to help increase birth rates, but not sure how helpful that's going to be.
