Ever extending use of computers in late 1950's gave rise to the great demand for standards in the field of Information Technology. To meet this demand, ISO established in 1960 TC 97 "Computers and information processing," and the next year IEC founded TC 53 with the same title. Before long, while the IEC parallel came to a standstill, ISO/TC 97 grew into the biggest technical committee comparable with none in ISO and IEC playing a major role in IT standards development. In 1987 having absorbed IEC/TC 83 and SC47B, ISO/TC 97 became the first ISO/IEC joint technical committee, JTC 1.

Recognizing the necessity for Japan to participate in the ISO/TC 97 activities, the Information Processing Society of Japan (IPSJ) established Standards Committee in 1962 under the auspices of the Ministry of International Trade and Industry(MITI) and corporate sponsorship of computer manufactures operating in Japan. To improve Japan's standing in the international standards arena, this Standards Committee, through changes its name and structure several times, finally evolved into the Information Technology Standards Commission of Japan (IPSJ/ITSCJ) in 1986, one year before the establishment of ISO/IEC JTC 1.

In November 1987, IPSJ/ITSCJ proudly hosted the first plenary meeting of ISO/IEC JTC 1 in Tokyo. Since then, IPSJ/ITSCJ has been devoting its efforts to standards activities in the field of Information Technology, dealing with most of ISO/IEC JTC 1 matters.

The founding President was Professor H. Wada followed by Prof. S.Takahashi, Prof. A. Tojo, Prof. S. Ishizaki, Prof. K. Ohmaki and the present President is Dr. S. Ito.


The mission of IPSJ/ITSCJ is, mostly under commission from METI (Ministry of Economy, Trade and Industry, formerly MITI), to contribute to the development of international and national standards in the field of Information Technology by managerially and technically participating in the international activities in ISO/IEC JTC 1, by transposing international standards into national standards, and by drafting original Japanese Standards.

Structure and scale of IPSJ/ITSCJ

As of 2010, IPSJ/ITSCJ consists of some 90 committees and its members total approximately up to 1037. The current structure of IPSJ/ITSCJ is given in Figure below:Organization of IPSJ/ITSCJ

In this Figure, Category 1 committees fundamentally mirror JTC 1 subcommittees to deliberate technical work and do position taking representing Japan.

Category 2 committees prepare Japanese original proposals for prospective international standards. All of IPSJ/ITSCJ's original work is carried out in the committees of this category.

Category 3 committees write Japanese Industrial Standards (JISs) primarily based on published International Standards.

In 2010, IPSJ/ITSCJ held 604 meetings, including 7 international ones, and dispatched 1429 delegates to international meetings.

JTC 1 officers offered by IPSJ/ITSCJ

IPSJ/ITSCJ offers the following JTC 1 officers:

  • SC Chairmen:3
  • SC Secretariats:4
  • WG Convenors:19 (including five offered by JBMIA)
  • Project Editors:113

These numbers of officers show that IPSJ/ITSCJ's contribution to international activities is around at the average and acceptable level as an organization of a technologically advanced National Body.

Liaison Organizations

To carry out its work efficiently, IPSJ/ITSCJ maintains formal liaison with the following organizations:

  • Japan Business Machine and Information System Industries Association (JBMIA)
  • Japan Electronics and Information Technology Industries Association (JEITA)
  • Japanese Standards Association (JSA)
  • Telecommunication Technology Committee (TTC)
  • Ministray of Economy, Trade and Industry (METI)
  • Ministry of Internal Affairs and Communications (MIC)


IPSJ/ITSCJ is also committed to undertake the development and issuance of IPSJ standards as its original deliverables. The purpose is to offer technical information and data that are not mature or appropriate for formal standards but will be useful for technical work and R&D activities in this field.

IPSJ/ITSCJ is determined to continually strive for the sound growth of IT industries by promoting standardization in the field.
