The toxic culture in Japan stems from the unspoken expectations.
You have a 40 hour schedule, but you’re expected to be in the office for +60. You get vacation time, but it’s shameful to use it. Women (particularly young women) aren’t given promotions or professional advancement because it’s assumed they’ll quit to become housewives as soon as they find a husband of a higher station.
All that shit you hear about microaggression, implicit bias, and structural racism run rampant in the Japanese corporate world.
