Hi
@elio789, just out of curiosity, what makes you want to finish your degree (and later live) in Japan? Have you considered testing the waters with the exchange program first, if that's feasible?
Have you started learning Japanese already? If Japan is in your future I cannot overstate the value of studying the language as much as possible before you go. If you plan on living in Japan and want to make a living that is not based on your foreign-ness (and be fully functional and independent), language ability will be imperative.
At any rate, I recommend reading up on your options and choose based on which school will offer a quality education in your chosen field, and if you intend to stay in Japan, provide you with quality connections that may help you develop your future career. Try to find first-hand experiences from current and former students.
I only bring these points up because answering will help strengthen your resolve and make sure you land on your feet. Do keep us updated please.
