If you would only like to live in Japan for a short time, then your best bet may be to join a Japanese school. That will help you learn the language and the language school will take care of applying for your visa and usually will help you with living arrangements. Attending a language school also doesn't require that you have a college degree. It is important to realize that you will be in class 5 days a week, but it will certainly help your Japanese.

As far as getting a job, a college degree is a must. Also, if you would like to do something other than teach English then you will want to gain skills in Japanese.

Good Luck!
