Programming in Japanese

Or any other language.

Anyway, I'm just curious; if you're a native jap or something and only speak ______, do you need to learn english to program? what about html? on any foreign language site I've looked at, the source is always written in english...

Bumping ancient thread with an actual answer, albeit in the form of a lazy-ass Wikipedia (ass-Wikipedia?) link.
