Pros
Stable job. Japanese culture requires great attention to detail and making deadlines. Therefore, the general workforce is held accountable for their deliverables with great discipline. This enhances transparency across teams from a project dependency standpoint.
Cons
Process and procedural workflows are important to the culture so everything in the organization requires tedious tasks which causes tremendous loss of efficiency. Culture also promotes staying late at work for the sake of face time. This depends on your direct manager and their preference. Systems and workflows are antiquated, and upgrade decisions are not made from a process optimizing standpoint but from major political influence. Great deal of lies are hidden beneath the surface with politically correct speech and false reporting with the purpose of personifying a positive image. This is so embedded in their culture it cannot be changed.
