Background: Joichi "Joi" Ito (Yi Teng  Rang Yi , Ito Joichi, born June 19, 1966) is a Japanese activist, entrepreneur, venture capitalist, and director of the MIT Media Lab. Ito is a professor of the practice of media arts and sciences at MIT and a visiting professor of law from practice at the Harvard Law School. Ito has received recognition for his role as an entrepreneur focused on Internet and technology companies and has founded, among other companies, PSINet Japan, Digital Garage and Infoseek Japan.
Context: Ito was born in Kyoto, Japan. His family moved to Canada and then when Ito was about age 3 to a suburb of Detroit, Michigan, in the United States where his father became a research scientist and his mother a secretary for Energy Conversion Devices, Inc., now Ovonics. Company founder Stanford R. Ovshinsky was impressed with Ito, whom he thought of almost as his son. Ovshinsky helped Ito develop his interests in technology and social movements, and at age 13 gave him work with scientists, saying, "He was not a child in the conventional sense."  Ito and his sister Mizuko Ito, who is called Mimi, spent summers in Japan with their grandmother who taught them traditional Japanese culture. At 14, he returned to Japan when his mother was promoted to president of Energy Conversion Devices Japan. He studied at the Nishimachi International School and for high school, the American School in Japan in Tokyo. Ito also learned "street language, street smarts, and computers". One of few Japanese using modems before deregulation of networking reached Japan in 1985, Ito had found The Source and the original MUD by his teens (and by 26 was working on his own MUD).  Ito returned to the United States to attend Tufts University as a computer science major, where he met, among others, Pierre Omidyar, later founder of eBay. Finding his course work too rigid and believing that learning computer science in school was "stupid", Ito dropped out of Tufts to briefly work for Ovonics. Ovshinsky encouraged him to return to school. He enrolled at the University of Chicago in physics but dropped out on discovering, in his opinion, the program at Chicago to be more oriented towards producing practical engineers than towards teaching an intuitive understanding of physics. In the Fall of 1985 he became the first student to register for a pioneering program of online courses offered by Connected Education, Inc., for undergraduate credit from The New School for Social Research.  Ito is one of Timothy Leary's godsons--a close non-traditional family-like relationship, an idea said to have been conceived by Leary for a few of his friends. Ito's sister is Mizuko Ito, a cultural anthropologist studying media technology use, and the musician Cornelius is his second cousin. Ito currently lives in Cambridge, Massachusetts, with his wife Mizuka Ito (nee Kurogane). Joi and Mizuka had a daughter, Kio (Hui Sheng ) on May 11, 2017.
