I should probably learn to read Japanese too... Being Chinese, I've got no excuse. Kanji is the hardest part and I've already got that down by default.
Japanese does fun stuff with kanji. They can mean 2-4 different things depending on context, and that's not counting grammatical conjugations. >_<
Hiragana and katakana are really simple though. I highly recommend anyone interested in Japanese stuff learn them, even if you don't think you're up to tackling the rest of the language. =)
