Besides "Mixi", what other social networking sites are popular in Japan right now?
Popular SNS sites in Japan:





Mixi: http://mixi.jp


Yahoo! JAPAN Days: http://days.yahoo.co.jp


GREE: http://gree.jp


Otaba: http://otaba.jp





Mixi is by far the most popular, but Yahoo! JAPAN's Days has a nice set of features and should catch up fast. Gree has some interesting features, but not everything seems to work and the interface is slightly confusing. Otaba...sorry, it doesn't look like an SNS that I am very interested in getting into. ;-)





Hope this helps.





By the way...there are more out there, but they are not very popular.
Reply:Yahoo Japan has started it recently


http://days.yahoo.co.jp
