I've only been studying Japanese for less than a month, so hopefully participating in this challenging will give me a huge kickstart to learning this notoriously difficult language. I don't know if I will be able to continue for the entire 3 month period, but I'm committed to participating for at least 2 months. So far I've been using the Power Japanese software from Transparent Language along with Pimsleur I, which I've been using passively. I've also just started watching the Let's Learn Japanese series and listening to the beginner's lessons at Japanesepod101.com. I've ordered the Assimil Japanese books and when they arrive they will form the backbone of my study along with the Let's Learn Japanese programs. I also have a few other learning materials that I may use from time to time.
