mixi, Inc. (ミクシィ mikushī ) (TYO: 2121) is one of several social networking websites in Japan and was started in 2004. As of May 2008, mixi had over 21.6 million users. The company that operates mixi, (now mixi, Inc., but originally called E-Mercury, Inc.) was founded by Kenji Kasahara in 1999 as a limited liability company and became a Japanese corporation in 2000. The company changed its name to mixi, Inc., in February 2006 to align its name with the social networking service that launched in 2004. It has its headquarters in Shibuya, Tokyo.
The focus of Mixi is "community entertainment," that is, meeting new people based on common interests. As is typical of social networking sites, users can send and receive messages, write in a diary, read and comment on others' diaries, organize and join communities, and invite their friends. Research indicates that some users, particularly young women, are more likely to use mixi to connect in more private ways with close friends, particularly in contrast to perceptions of Facebook as a more public social network.
Started in February 2004, there are now more than 10 million members and 1 million communities on mixi, and more than 2 million page views per day as of December 2007.
- Registration requires a valid Japanese cellphone number, which bars anyone who is not or has not been a resident of Japan. Since 2012, both Android and iPhone users can apply for a new mixi account via specific apps made for their devices.
- A community is a place for people to share their opinions through an online forum and a way to express tastes and hobbies.
- myMixi, or Maimiku for short, means buddy or friend. This is similar to a contact in flickr, or friend on Myspace, and involves an approval process. The maximum possible number of myMixi a user allowed to have is 1,000. Accounts that are marked as tarento or celebrities don't have this limitation.
- The word Mixi is a combination of Mix and I, referring to the idea that the user, "I", "mixes" with other users through the service.
- "Mixi Station" is an application that detects songs being played in iTunes and Windows Media Player and uploads them automatically to a communally accessible list in the "Music" section, and was implemented late in June 2006. By July 2006, support for Winamp was implemented via a Winamp plugin, which was quickly made official by Mixi.
- Batara Eto was the only developer at the start of the social networking site.
- Mixi heavily uses open source: Linux, Apache, MySQL, and Perl. It uses several hundred MySQL servers. Mixi also uses Tokyo Cabinet NoSQL database.
- A term "Mixi Fatigue (mixi tsukare (ミクシィ疲れ))" has been coined to describe the feeling of becoming tired of Mixi, voicing a desire to discontinue using the service, and finally deciding to terminate an account.
- Mixi added the feature to upload your own video content, along with the ability to post content from YouTube.
Mixi has enjoyed a steady growth in its userbase. In 2005, the website had more than one million users, and less than a year later, it had more than five million users. The site had more than 10 million users in February 2007, and as of July 2010, more than 30 million. This number includes deleted and multiple accounts.
Celebrity Accounts 
In 2008, mixi began "Celebrity Accounts" in which celebrities who are on the social networking site are allowed to surpass the 1000-friend limit and potentially have an unlimited number of followers.
Many popular figures have "Celebrity Accounts" such as actress, model, singer Anna Tsuchiya, producer and rapper Shing02, Akihabara idol Haruko Momoi and countless others including fictional character Arsène Lupin III from the series of the same name. Mixi maintained an official list of these accounts.
In 2011, mixi announced that it would end "Celebrity Accounts" and replace the function with a new service, "mixi page".
"By posting information, including diaries and the like, on this service, users grant the service the unrestricted right to use said information (whether in the form of reproduction, publication, distribution, translation, modification or the like) without compensation."
In December 2008, Mixi discouraged use of the site for dating, prohibiting users from “using Mixi mainly to meet with strangers of the other sex”.
