Facebook has introduced a feature to allow users to link their accounts with Japanese social network Mixi. This follows similar moves targeted at Google-owned Orkut and Hyves, a popular Dutch social network, which we reported yesterday.

Asiajin reports that the new export tool lets users update their Mixi accounts from within Facebook. It gives access only to existing Mixi features, and was probably made by Facebook without cooperation from Mixi. The Orkut tool, which operates in a similar way, was reportedly a unilateral Facebook effort.

Facebook has about 1.38 million users in Japan and the island nation was the second country to get access to its location check-in service, Places, after the United States. However, Mixi is the dominant social network in Japan and some reports suggest that even Twitter has more users in Japan than Facebook.

While the export tools are undoubtedly useful for some people who use two social networks, they can also be seen as an enticement to jump ship and join Facebook. It’s interesting to note that Facebook seems to be developing the tools only in select markets where it faces significant competition. However, Mixi does have different features to Facebook, including the fact that users can adopt nicknames and they always know who viewed their profile.
