There are now over 10 million active Facebook users in Japan according to the company, a number that doubles what was reported just six months ago. Like the iPhone, Facebook has taken its time to find popularity in the Far East, but Japanese users now appear to be warming to the concept. Its modus operandi of mandating real names and encouraging users to upload a lot of photos and personal information is very different to more traditional Japanese networks such as Mixi, where most people use pseudonyms and are reticent to show their face. Despite Facebook's sudden rise in popularity, Mixi still has the lead with 15.2 million active users (at least one login a month) reported last quarter and over 26.2 million users in total. However, with little growth over recent months the question is how long Mixi can hold onto its crown.
