The Seed of an Idea

The founder and CEO Yoshikazu Tanaka started GREE in 2004 from a personal passion and commitment to make the world a better place through the power of the Internet. Inspired by the technological innovation that was emerging from Silicon Valley at the time, his idea was to create a new community that would transform the way people communicate.

The Origin of the Name

The name “GREE” is a play on the phrase “six degrees of separation,” which describes the notion that one individual is no more than six personal connections away from any other given person on the planet. The idea gained mainstream popularity around the world following the small-world experiment conducted in the U.S. in 1967 by the social psychologist Stanley Milgram to examine the average path length of actual social networks. The name “GREE” was chosen with a sense of purpose: an intention to use the Internet, and the network-based communication that it represents, to create new forms of fun, convenience, and excitement.



Launching GREE on Mobile

The GREE social networking service was launched on mobile phones in 2005, ahead of competitors in Japan. Additional features were subsequently added, and GREE became the first invitation-based social networking service in Japan to host mobile advertisements. The service garnered high praise from the advertising industry for the sophisticated audience targeting it enabled.
