Pros
Stable income even if you don't have good output as long as you are hired in Japan. Flexible at working hours. 20 holidays / year.
Cons
Management is just focusing on internal politics and completely got lost. They don't discuss about improving the organization and change the way. They stick to what they have experienced and future new businesses and just improving the current system. They hate to face the big problem why we keep loosing against other tech companies for 30 years and living everyday with their inertia. Working hour is long. It's 9 - 22 in my case. Too much work but less human resources. 50 % of colleges are low motivated and have strong tendency not to work voluntarily and independently because of too much work. Strong tendency of not taking risks and try to collect too many information and doesn't make decision after this long processes. This company is famous with the culture of "Bottom UP style", but not anymore in this 5 years.
