Cool site with a good podcast that's been around since 2005 and offers a wide range of podcast topics and learning levels.
Also lots of other good resources on the website, including info about "Weird Japan", JPop, Anime and Japanese study guides and books.
"Learn Japanese with our free Japanese lessons in podcast format. We use examples from anime and everyday conversation to teach you Japanese that is useful for everyday life. Hitomi-sensei is from Tokyo and will teach you to speak with the most common Japanese accent.
