Since 1998, many organizations have been involved in the setting industry standards to improve the accessibility of the information technologies and services in Japan. In 1998, JISC (Japan Industrial Standards Committee) established a Special Committee for older persons and people with disabilities. This Committee submitted "Proposal of the Ideal Method of Carrying out Standardization Policy for Older Persons and People with Disabilities" to the Minister of International Trade and Industry. This proposal shows the basic concepts such as "Fundamental Principle of the Needs of Older Persons and People with Disabilities" and "The Ideal Method of Carrying out Standardization of Older Persons and People with Disabilities". By this proposal, developments of the products for both individuals without limitations and people with disabilities, and activities related to the standardization have been started. In 1999, JISC organized "Special Committee for Standardization Activities in the 21st Century". The Committee pointed out the necessity of standardizing the method of product design (universal design, accessible design) and standardizing the collecting and measuring method of human data such as visibility of older persons.

Before this suggestion of the policy, we can observe some guidelines have been prepared for each technology field. From 1974 to 1976, the Ministry of International Trade and Industry (MITI, currently changed to Ministry of Economy, Trade and Industry) entrusted "Investigation of Contribution Plan of Rehabilitation toward People with Disabilities" to Japan Electronic Industry Development Association (JEIDA, currently JEITA after unification with Electronic Industries Association Japan). It became the start of the long activities of the guideline preparation by MITI. In 1988, MITI ordered JEIDA to do the investigation for providing against the super-Aging society to prepare "Electronic Products Accessibility Guideline" in order to promote the development of electronic industry, which was friendly to people with disabilities and older persons. This was realized as "Computer Accessibility Guidelines" in 1990. MITI revised this guideline and published Notice No. 231 "Accessibility Guidelines for Use of Computers by People with Disabilities" in 2000.

In the telecommunication field, in 2000, the Ministry of Posts and Telecommunications (MPT, currently Ministry of Public Management, Home Affairs, Posts and Telecommunications) announced "Description of Accessibility Guidelines for Use of Telecommunication Equipment by People with Disabilities" in Notice No. 515. In the same year, the guideline "Accessibility Guidelines for Use of Telecommunication Equipment by People with Disabilities (the first edition)" was published.

MITI and MPT are making two similar guidelines for computers and telecommunications equipment. This fact symbolizes the problems of the vertically divided bureaucracy. Along with the progress of the technology, distinction between information processing and telecommunications becomes vague. If the products are distributed in different standards (but still looks alike), consumers will get confused. People concerned should start the activities for harmonization of this matter.

Need of the Sector Guideline

After taking into account both the needs of people with disabilities and older persons and the global trend of accessibility issues, INSTAC (Information Technology Research and Standardization Center) keeps maintaining the standardization activities. In July 2001, the new committee was established (see Note) by the several organizations related to information and telecommunication accessibility issue to collaborate on the following.

  1. A sector guideline of information and telecommunications field based on ISO/IEC Guide 71 for the domestic standard. As for the activities for making a sector guideline, it should be conducted by combining the methods of top-down and bottom-up, such as lining up the items from Guide 71 by top-down, and extracting the specific standards by bottom-up for each item from individual guidelines.

  2. Sharing information among organizations related to this field.

  3. Harmonization among guidelines that each information and telecommunication related industries makes. Harmonization among governmental organizations and harmonization among guidelines e.g. web accessibility guidelines in some countries. It is important to bring specialists in human science and social science field to participate in the harmonization activities because we see the language related issues in guidelines e.g. WCAG of WAI for instance.

  4. The policy that makes people with disabilities and older persons participate in the standardization activities and the research and development. The government may need to prepare education programs, and corporations and academic communities should cooperate for that.

The Sector Guideline as An Industrial Standard

The sector guideline consists of basic principles that the information and the telecommunication industries shall, should and may meet when they develop their products and provide their services. Unlike the section 508 of the Rehabilitation Act of the United States, this guideline is an industrial standard. However, it gives, in fact, a great impact in the procurement, because both central and local governments in Japan respect Japanese industrial standards, JIS and they usually require vendors to meet JIS when procurement.


This Guideline is placed in between ISO Guide 71 and the industrial guidelines in each different industrial fields (see Fig.1). When this guideline becomes one of JIS, information and telecommunication industries shall refer when they develop their products and provide their services.

Time Frame

The time frame that JSA committee plans is the following.
Public comments : By the end of December 2002
Final Draft : By the end of March, 2003
Authorization : By the end of 2003


First, we report Japan's activities on the standardization of information technology accessibility. Second, we overview the on-going projects related to standardization among industrial fields, such as the computer industry, the software industry, the information service industry, the web related industry and the telecommunication industry. Third, we discuss the harmonization of guidelines and standards in the international perspective.
