Mixi: Japan’s social network

Mixi logo

[Update 2011-03-08] Mixi was passed by Gree in 2010, and likely to be passed by Mobage Town, too. See this.

Mixi is the biggest social network service in Japan.(was the biggest until summer 2010). It has 11 million users so far. It's a phenomenon. Before Mixi, the Web was not attractive enough for non-techie people. Mixi changed that. Mixi changed the daily social life of Japanese people.

Batara Eto - an intern from Indonesia - proposed the project to clone Friendster in 2003. He developed the site in the next few month. The site was named 'mixi'. It's quite a remarkable example which shows the diversity of the workforce is the key to success.

Mixi is not very different from Friendster, but there is a small but significant difference from Friendster or Orkut. Mixi has a blogging feature. It really helps to keep users visiting the site. Mixi is actually a social blogging tool.

The company's name is 'mixi' too. Its former name was 'e-mercury' but the name was changed to 'mixi' after the huge success of the service. Initially, the company was founded as an Internet job agency. The job agency service, 'find job', is a quite profitable business too.

The founder Kenji Kasahara is a young quiet person. He looks like an introvert 'Otaku' kind of person. Probably he's a much more acceptable role model for the younger Japanese generation than aggressive Livedoor or Rakuten founders.

    I would like to join Mixi–could you invite me?

  • http://akimoto.jp/blog/ Akky Akimoto

    Mixi is now open like Facebook. You may register by yourself but it requires your Japanese cellphone e-mail address. That is asked when you are invited by current users, too.
