MIXI is Japan's largest social networking site, mainly providing online functions such as diaries, groups, and albums. It went public in Japan in September 2006. Currently, MIXI's traffic ranks second only to Yahoo! Japan, with a monthly page view of 11.8 billion, and it has over 15 million registered users.
Shanghai Mixiu reportedly has reached an exclusive strategic cooperation with Japan's MIXI. Its page design and function settings are very similar to MIXI's, but its friend database and others have not been connected with Japan's MIXI.
