      Pros

      The company has several products, the office is in Shibuya Sakura Stage, and some members have good technical experience to learn from.

      Cons

      Not an innovative or challenging environment, the salary is very low, flexibility is very difficult, and the bureaucracy is very bad. Furthermore, there's a lot of office politics and employees don't get rewarded easily.
