Typical Japanese work culture. A lot of workers are overworked, myself included.
Hiring Manager was not honest about OT needed, days of work may as well be 6 instead of the typical 5.
HR needs to learn to listen and respect its lower paid workers. Only started to take action when it was too late.
AM is inexperienced with managing people. Lots of emotional drama during work.
Fear-culture.
A lot of integrity issues.
Safety is almost non-existent.
If you're a fresh grad looking to start a career, try something else, please.
