Learn Japanese is a trivia game designed to help people memorize Japanese words.

Release notes:

Konnichiwa! This is my most comprehensive version yet, pretty much all the core features I wanted are fully functional. There’s now a total of 6 stages, but in order to access the 6th stage you must complete stages 1 – 5. As usual I added more audio and images. I also included a nifty video intro featuring Kirsten Dunst in the PSP XMB menu, check it out.
