Ponlork has updated his Learn Japanese app for the PSP:

Heres whats new:

I fixed the Championship Mode, it should be fully functional now. This mode is for advanced users who are familiar with the Japanese writing system. Use the analog stick to shift the characters up from Ka to Ga, Ha to Ba etc. I also added a sound file to test, I plan on having audio pronunciations of all the words.

Future Plans
- Menu
- Audio Pronunciation of each word
- Custom Questions! (A MUST)
- Random Mode
- Conversational Phrases
- Karaoke

here's a video demonstration of the game
