The Japanese take everything with protocol very seriously, both to their benefit and detriment. I saw a middle aged salary man cleaning up a few pieces of street litter at his bus stop. I also witnessed about 15 people letting some guys get stuck in an elevator cause they couldn't figure out how to operate it because interfering might be embarrassing for the victims and you don't get involved in a stranger's day like that.
Japan is a quirky place. It was very tiring for me because I felt so... monitored the whole time I was there. Not by the government really, by everyone.
Loved to visit but I'd never survive there long term.
