This week's news that Japan is the first country outside the U.S. to to get Facebook Places might have come as a surprise to many. While social networks abound here, online privacy kerfuffles are common and the average Japanese prefers avatars and pseudonyms to real names and identities. Would this nation really embrace an application that broadcasts their movement in the real world?

In case you haven't heard, Facebook Places is a geolocation app that allows users with GPS-friendly cellphones to "check in" whenever they arrive at a location  – and "check out" when they leave. This effectively makes your movements transparent to your social network online, so you can meet up with nearby friends, if you wish. But Facebook aren't exactly foisting this app on a hostile market: Similar platforms such as  Livedoor's Roketacchi (Location Touch), BrightKite and Foursquare have already proved popular here.

However, it seems odd that geolocation software is such a hit, seeing as traditionally personal privacy online is closely guarded in Japan. Google came under a barrage of criticism when they launched Google Street View, with many complaining that private moments and dirty laundry had been unnecessarily displayed online. The upshot was that the company were forced to reshoot its footage at a lower angle – at considerable expense. Privacy is a big issue even among users of social networking services such as Mixi, where many users veil their identity and avoid posting pictures of themselves.
