Actually, it doesn't have to be "only English", it just has to use roman characters. There are a large number of keyboard layouts/input methods you can choose for the "romaji" mode of kotoeri input in Japanese, including French (i.e. AZERTY keyboards), German, Spanish, etc. Just browse to Kotoeri Preferences and you'll see it in the leftmost tab.
Personally, I just use a Japanese iBook. There's a "kana" button on the right-hand side of the space bar, and a roman character/arabic numerals button on the left-hand side of the keyboard. What could be easier? (Plus, I've heard that English-language Apple keyboards don't have the CTRL button next to the 'A' key, which is where I like it for BSD stuff).
