Pros
Good company to join for young people with no job experience. Will be able to learn about business while working. No layoffs in Japan, as you get older salary will increase unrelated to performance. People are nice. Good company if you want to under perform and but still do not get laid off.
Cons
Work efficiency is horrible. Employees has low base pay so they perform unnecessary over times. Very low salary compare to the market. Since there's no layoffs, some people does not contribute to the company but still get paid higher than the high performer since they are older. The senior management tells their employees one thing, but their action is completely opposite. Seniors decides everything. Not open to new ideas. Their reason is, because we been doing this process for years.
