Programming in Japanese?

I may or may not be moving to Japan within a few years, and I'm a novice programmer. Is there any difference programming when you're in Japan? Do they utilize kanji? Do they use the same programming languages as everyone else?

Eh, whatever, I guess I'll disregard their customs when it comes to programming wether I ever move there or not. I mean, as much as I prefer Japan over good ol' 'Merica, english is more or less an international language by now and even if the locals don't like it, there's always online distribution. It's not like your code needs to be in Japanese for your game to be, either.
