i dont know were u are from, but here we have exchange program too and u dont need to know any japanese (it would help if u knew) but u just have to have good english, they teach u before u go so u can go to school there. of course the more u know about english/japanese the better.
They have it for highschool and for masters degree as far as i know, but then again it depens on your country, i saw this directly on the japanese embasy site of my contry!
Good luck
