This is a question of your font renderer. A vector font rendering
engine will not use bitmaps at all. If you write your own font
renderer, you'll probably use bitmaps. But kanji is not an alphabet, so
you're not likely to need the entire character set; you might only need
a few dozen characters (plus kana).

Roughly speaking, you should assume western characters are 1/2 the
width of Asian characters. So the "correct" thing to do is use 16x16
for kanji and kana and 8x16 for Western text. However if you are
displaying romaji in a Japanese environment you should use 16x16 for
consistency with other operating systems. In other words your user
interface should be designed around 16x16 in Japanese mode and 8x16 in
Western mode.
Note: to implement Japanese text you need a minimum of (some number of
kanji) + all of hiragana + all of katakana.

So we are talking about a 32-bit processor with lots of RAM and ROM,
which means you want to use an operating system (or you really like
pain). I suggest Linux and X.
