Twitter Japan launched today at Twitter.jp via a partnership between Twitter and Digital Garage. It’s basically Twitter, in Japanese, with display ads.

A sizable Japanese userbase has grown up around Twitter, despite the fact that it is only available in English. So this certainly makes sense. I’d expect support for other languages to follow shortly as well.

And since Twitter is now a utility, there’s no need to bother making it stable before embarking on a glorious expansion crusdade. Congrats to the Twitter and Digital Garage Teams.
