Toxic japanese work culture - super hierarchical, overtime is a standard (kind of expected from you), constant micromanagement, you are never good enough for the managers, a lot of stress,
Huge open space office with a depressing 90s design,
The work system is so toxic that everybody is trying to find a workaround - faking data, being friends with the right people etc.
Very bad relations between departments, constant negative commenting and blaming
Requires a lot of non-sense travelling - normalizes having 50+ flights a year for 1-3 days business trips.
