My local community college offered Japanese classes, and I took the first one. I was able to get it covered by financial aid. Unfortunatley I was unable to progress to 2, 3, and 4 for stupid broken body reasons, but they are there for me to take whenever, financial aid and all. The instructor even leads a 2 week trip to Kyoto every summer for J-students.
Perhaps there's something like that available for you? If not, the "Genki" series of books seem to be the standard for those courses, so you can learn on your own. Flash cards help too.
