Katakana is the one with aphlabet, if you want to put it that way? (thanks for the name Sue_Kitsu) Most of the video games use this Katankana system. which I really want to learn. kanji is basicly chinese letters and hiragana is the one I never understand, the only symbol that I know is "no" identical to the something "no" jitsu in Naruto :| Hiragana is the most used in Japanese. While Katakana is used for the foreign words. (Like chocolate), and there is writed in Hiragana over the Katakana (Usually) While Kanji often is for places, city names, mountains etc, etc. Edit: "No" in Japanese is "Iie, iie no", and "yes" is "hai" :P
