JapanesePod101.com is a language course, podcast and accompanying website that offers lessons in Japanese.
It’s a “fremium” site meaning you can sign up to the site for free and access lost of resources on there, including the podcast. For the more advanced features they have a subscription service starting at just $4 a month, with a little bit of searching you can regularly find promotions and discounts too.
As far as features go, there is lots on there. The site is arranged by level from Beginner through to Advanced with each level containing 50 or so lessons. Each lesson has a podcast, a review track, dialog and downloadable PDFs with lesson notes and transcriptions.
If you sign up to Premium (I’ve only ever used basic so far) then there are lots of other features too including flash cards, slideshows, word banks and dictionaries.
You can listen to the podcasts through the site itself or download them to listen to them later. To make it even easier, if you download the “Innovative Language” app (iOS and Andriod), you can download whole sections at a time to your phone or tablet and then listen to them at your leisure.
