no Japanese language/fonts/input in non-Japanese 3DS units. it was removed entirely, save for browsing, which displays them just fine.
The fact that it's part of the browser and the browser isn't seperate software (it's part of the main 3ds firmware/os) I'd say the fonts are probably there
But yes, there is no way to access or use them directly... but I'd think there is no reason why there couldn't be a webpage applet that would allow you to type in english and then it output in kana/kanji... The problem would be finding someone with enough free time and web developing skills to do so.
