Japanese use ordinary keyboard. You just have to install the japanese language pack, and configure this crap, and then you can select japanese as language, and write japanese with your standard keyboard. You just write the japanese with western letters, like arigatou and it comes out as ありがとう, then you press space to scroll through the different kanji's of the word(meaning the different signs like the ones in chinese written language) and you get 有り難う。Sorta like using the T9 dictionairy on a european cellphone.
