Assimil:
Japanese
One of the best methods around for learning a language. A bit on the pricy side, but you get what you pay for. Pure quality. -Regrettably, this link contains no audio CD

One of the best platforms out there for learning Japanese. Try the free version or subscribe for better features.

Pimsleur: Japanese
A wonderful method for learning a language on the move, especially when you already have a good basic understanding of the language. Click here for a free 7 day trial.

Teach Yourself: Complete Japanese
Not an ideal course for a complete beginner, but excellent as a review and as dialogues to memorise.

Colloquial:
Japanese 1
Similar to the Teach Yourself method. Very good for extra reading practice.

GENKI: Series
When I was at university studying Chinese, many of my coursemates were studying Japanese with Genki. I haven't used it, but I can't wait to use this series.

Cortina:
Japanese
A great method that can be used as a review after Assimil, or as a stand-alone text. Textually heavy.
