Or, you could consider a more realistic route. Take an intensive Japanese course in Japan to manage the JLPT (A few universities will let you in with JLPT2 instead of one if you`re going to also be taking Japanese classes at the university), and then enroll in a Japanese university.
Having JLPT1 definitely puts you at an advantage, and opens up the doors to universities that do not have a strong foreign student program - but for someone who wants to study Japanese in Japan it isn`t always necessary.
