What's the type of font used in manga (japanese comic books)?

Answer 1

Well, it is a little simplistic to denominate it a "font" considering that they use three type of characters: Katakana, hiragana and kanji. It can not be used as the other fonts in windows, because you need an "ima" program that allows you to type the sound of the word and let the computer to guess which is the symbol you want to use.
Hiragana is a system of sylabics used to write japan native words.
Katakana is another system of sylabics used to write non-japanese native words.
Kanjis are the same characters used by the chinese language. The symbols are the same but the sounds are different.
