I just got done taking an online Japanese course through my community college. It's not really a college credit course... hard to explain... anyway - anyone should be able to take it if you're interested. It's conversational Japanese. It helps if you're going there for a visit... how to make a hotel reservation, use the train, ect ect. And it teaches you the basic sentence structure. It's a good way to just learn the basics. You can check it out here:

There are more languages too if you're interested. (Even English as a 2nd language.)
Just thought I'd share in case anyone was interested.
