Japanese working environment

Today is the weekend.
Yesterday, I had to work overtime until 11.
That was my first experience in my life.

I don't know if other countries also have to work overtime like Japan.
But,I dont think so.

I think foreign workers value praivate as important as work.
That's right, it's not usual.
Japanese working environment is completely insane!!!!

Please tell me, What do you image Japan is like???
