To be fair to the people at Innovative Language, don't cr@p all over them due to a technical issue on Audible's part. I usually download audio books in Format 4. That version came in corrupt, and I was only able to hear, "This is Audible." The Enhanced version works perfectly.
Also this is a short, free preview of their box set, which is a rehash of the audio content from Japanesepod101. This maybe more convenient to a few of us. As far as content goes, this is great for the beginner. Maybe even better than Pimsluer's Japanese. I still believe you should use more than one program to learn a language because different programs will tackle a language from different angles. But if you're a newbie, this series is a great start. Then I would incorporate Micheal Thomas. Later on Pimsluer's. As you learn, also immerse yourself in Japanese culture and media. (websites, KeyHileTV, manga, etc) Also learn Kana, Katakana, and Hiragana.
Don't take my word for it, download all of the freebees, and try out the lessons for yourself.
