going to japan to learn japanese

iam a us citizen and i would like to go to tokyo or somewhere close to that to a college to learn japanese and i was wondering i have no knowledge of japanese and i wanted to know if they had college campuses for me to stay in and maybe where to visit on the internet for a college that is not hard to get into that would allow this....

You could come to Japan to attend a full-time Japanese language course at a school dedicated to such language study - they often have one or two year courses available for people who want to prepare to attend a Japanese university.

At colleges/universities in Japan, all lectures will be in Japanese, so you need to be quite good at the language to complete a degree course.
