how to write Japanese

I dont get what you're trying to say, but in my opinion, you should try to understand the spoken language before you actually focus-focus on writing. Try watching anime/dramas (not the dubbed ones) Try memorizing the Hiragana and Katakana chart first, and try to write them, before starting on Kanji. happy mylotting!

Japanese writing you mean? There are three japanese writing system, Hiragana, Katakana and kanji. Hiragana is set of symbols most akin to japanese alphabet. It is made up of entire syllables. It can be used to spell out any japanese word while katakana is used for foreign words that have been imported into japanese. If your name is not japanese, katakana is the set of syllables that would be used to spell it. While kanji is the most difficult to write among the three. It is set of symbols derived from chinese writing system. If you are going to japan, i advised you master the katakana and hiragana. Most kanji characters are written with a hiragana above it. Oh, before i forgot there is this called romaji writing. In this system you used English alphabet in writing japanese words. It is frequently used by foreigners who have not yet mastered the hiragana, katakana and kanji. :)
