Avantages
For those interested in relocating to Japan, there is that. Co-workers and most employees are for the most part nice and respectable. It is said to the point of boredom now but the free meals are nice, but be forewarned, breakfast & dinner are after typical work hours.
Inconvénients
Several managers are not the best and many aren’t even qualified for leading people let, alone a team. Salary is atrocious and monetary compensation is very weak for the type of company and industry. Little opportunity to grow career wise (i.e. senior engineer here with years of project management experience and management) and not easy to move. High turnover. HR responses to any issues are very poor with respect to time, often need to ask again and again.
