I applied through the Boston Career Forum, specifying that I was interested in a business position at the company. The process was extremely straightforward. I applied through the Forum's site, after which I was made to make an account on the Rakuten recruiting site. I then took an online proficiency test, watched an online presentation about the company, and wrote an essay covering my thoughts on a topic from the company's CEO. After completing these steps, I was allowed to schedule an interview via Skype in either English and Japanese. I was contacted on Skype exactly at my scheduled time. The interviewer was very friendly and her questions were straightforward, basic interview questions. If you've prepared you will have no trouble at all. The interview took about 20 minutes.

I applied online through their website. The entry sheet was pretty simple and straight forward. Then did the aptitude test. I just had my 1st interview and got through to the 2nd round. Took it in Japanese. And it was a group interview. The interviewer was very nice and friendly.
