Pursuing a Pharmacy doctorate in Japan

Hi, I'm currently studying pharmacy and after I graduate I will have a bachelor's degree, but with that degree I will only be able to work in my home country. I also want to further my education by getting a pharmD and it is only possible through international studies.

I intend to apply to Taiwan (NTU, TMU) but I'm also applying to Japan (University of Tokyo, Tohoku University). I was wondering if I would be able to enter a PhD course with my 5 years of school/bachelor's or would I have to go through the entire 6 year pharmacy course in Japan before I can apply for the PhD course. Or would I need to get a masters degree before I can get a doctorate?
