I'm curious because it seems very difficult to write in a keyboard with Kanji, Hiragana, Katakana, etc, characters. Do they have a different keyboard or use the same as most people in America and Europe?
I'd say it isn't too difficult to write Japanese in a keyboard.
There are tons of different keyboards! Theirs has Japanese on it.
There are many Japanese keyboards :) But many that type in the romaji (english) letters and search for the kanji/character that they want.
