Pros
Big company to work for where you can definitely encounter a different culture and a lot of Japanese colleagues. Actually pretty diversified company and people are generally friendly and welcoming. You can also enjoy free Japanese classes and some other cool benefits.
Kontras
-No real growth with the company -Top Management is not the best -Lack of real talent at all levels -Communication is a major problem, it doesn't go both ways instead it only goes from top to bottom -Company culture is very Japanese, they have a mandatory weekly Asakai that is a waste of time. They are very specific about you getting to the office at 9:00am sharp even if you never leave at 6:00pm sharp. The office is dead boring and does feel like a military base so if you are used to a Western work culture DO take this into consideration as you won't be happy at Rakuten
