Investment Banking in Japan : how open is it to the foreigners?

I'm Korean and I'm in my late 20s. I speak Korean, English, and Japanese. So I'm trilingual and hope to find an IB job in Japan after I graduate MBA there. I graduated from University of Toronto in 2014, went to serve in the Korean army for two years, and was employed by the biggest commercial bank in Korea. I worked at a branch as a junior loan officer and my primary role was credit analysis, company research, etc. for two years. I just quit the job and I'm entering Kyoto University MBA next april. Also I'm working on my CFA exam. SO MY RESUME WILL BE SOMETHING LIKE : University of Toronto(BA) + Kyoto University(MBA) + CFA lv.3 candidate + 2+ years of corporate banking in Korea + language skills(trilingual) After all, I want to get into an American/European IB or HF in Japan. But I wonder how open the Japanese financial market is to foreigners. My Japanese is not perfect, but I'm sure i can make a business-level Japanese until I graduate from Kyoto MBA. If there's anyone here who knows about the Japanese market and tell me what I should add up to achieve my goal, please reply. Thank you.
