i want to learn Nihongo.

do a search and it will be given you a lot of choice they are mostly free. I was using online translation site for free.

I too am studying Japanese and can give you links to a few websites which I think are useful. I also know of a tutor who teaches Japanese by email, and I can give you a link to his website if you like. His 40 lessons cost $45 USD but the first two are free. japanforum.com thejapanesepage.com japanesepod101.com - Gives a seven day free trial. You can listen to the audio files for free. The memberships gives you access to PDF files and other resources.

livemocha.com is better than rosetta stone and compleetlty free also thejapanesepage.com helps with the basics! :]
