for free please!
I would use japanesepod101.com. They have flashcards, word banks, and a ton of audio lessons. I recently subscribed there myself. They can also email you a "Japanese word of the day". It's a fun site.
Thank you very much Honeyclover !!!

I learn some Spanish from there, but if yo want to start a course you have to help others first.
