Chances of getting accepted into a JApanese university (especially) for a foreign student are quite low and you have to be a Straight A+ student in Japan to get in, only making it even more so difficult for a foregner.

However, you are probably aware of this as you are so dedicated and organized about this. If you stick to your goals you do have high chances of getting in (assuming you are a high ranked student) I also suggest you to get into a high ranking high school as well if you're not in one already.

Good luck and do your best ^^
