Process of establishment

 The enactment in 1985 of the Telecommunication Business Act introduced the market mechanism to the field of telecommunications. In October 1985, The Telecommunication Technology Committee (TTC) was established with three primary objectives: to engage in standardization concerning telecommunications, to disseminate standards and to contribute to the vitalization of the telecommunications sector. The scope of the TTC’s standardization activities subsequently expanded in parallel with the development of information and communication technologies, leading, in June 2002, to the Committee redefining its activities as “standardization pertaining to information and communication networks” and changing its Japanese name accordingly. The TTC has since restructured its organization to that of a general incorporated association in line with the Incorporated Association Act after obtaining the approval of the Cabinet Office in April 2011.
