yeah what youre asking is pretty broad and very hard to answer, otherwise i'm sure you would have figured it out yourself already.

mercedesjin makes a good point, figure out which uni you want to go to first. that then will determine everything else as, obviously a uni in tokyo will be much more expensive to live through than university of inaka.

if you prefer to study in english, thereby getting rid of one of your obstacles, i would have a look at the universities in nagasaki. i met a guy at my japanese class who studies there and he said they get lectured in english.

other than that, japan is a first world nation, so pretty much everything you want you can find, how much it will cost you however is something else entirely. besides personal luxuries, get your medical stuff in order if you need to.
