Rakuten

English speaking company in Japan! So you can use only English.

Twice a year: performance review and evaluation.

There are a lot of trainings going on; half of them are in Japanese.

If your department doesn't show good results, your bonus will be very small. However, when they hire you, they tell you that the bonus will be equal to one month's salary.

There are a lot of regulations that can be really annoying.

If you're in a department or team where there are a lot of Japanese, you will probably work overtime.

The CEO is trying to make Rakuten a fast-moving, global, innovative company; however, it is hard for a big Japanese company to have a startup spirit.

So, I would advise creating something like a Rakuten incubator for startups and investing in good ideas. You can even start this activity within Rakuten, as there are a lot of talented people who can create more interesting things than they are currently working on.
