How do I learned Japanese

My university doesn't offer this language, and I don't want to wait until graduate school to learn it under the assumption both that I will go to graduate school and that they will offer it where I choose to go.

I'm just curious, are there any good self-study programs I could work on for a year that would allow me to be the equal of someone who studied the language for one year in high school?

Ironically, there is a study abroad program in Japan which requires some experience with the language (using the example I used above as its own example of how much) even though they do not offer classes in it.

だれでも先生なし頑張れます。実は、クラスは必要ではないし、弱い者だけそんなことを利用していると思います。僕は完璧じゃなくて、毎日いっしょうけんめいに勉強していますよ。

そしてアニメがダイキライ！！例外は「あずまんが大王」で、大好き☆
