Hi there kumosayi, I have some information for you that you did not ask for explicitly, but it pertains to your case.
Pharmacists in Japan are not only expected to be licensed in Japan specifically (you cannot import your licensure received in another country), but to have attended a pharmacy program in Japan. That is, you cannot attend pharmacy school in your home country and then come to Japan and sit a licensure exam, if I recall correctly. Likewise, I would imagine, you cannot export your Japanese pharmacy licensure back to your home country.
At the very least you are looking at sitting for multiple licensure examinations. If you do school in your home country, you very likely would have to go through another degree program (possibly four year) at a university in Japan due to the way Japan handles the vocational training for being a pharmacist. Be careful about your decision, it is very unlikely that you will be able to easily practice pharmacy in two countries, if at all.
If you are dead set on being a pharmacist in Japan, you should apply to pharmacy programs in Japan.
Take my advice with a grain of salt, I am not a pharmacist, although I was on that track at one point. Do some more of your own thorough research.
