Web Accessibility

Accessibility means that people with disabilities and older people can participate in substantial life activities without any difficulty. In telecommunications technology, accessibility means that anybody can access web-based information and information technology tools easily. Improving the accessibility makes them easily accessible to people with disabilities and older people as well as those with no disabilities.

Improving the company’s website accessibility is also an essential element of business from a Corporate Social Responsibility (CSR) standpoint.

OKI started to include a new item for website accessibilities in “OKI Website Guidelines” enacted in 2002, and in October 2004, it compiled the more rigorous guidelines “The Accessibility Guidelines” which meet JIS standards. Then in March 2008, “The Accessibility Guidelines” were revised on the basis of baseline level of achievement “A“ of "WCAG (Web Content Accessibility Guidelines) 2.0" complied by W3C/WAI. In addition, it was revised in November 2010 on the basis of “Guidelines for older persons and persons with disabilities -- Information and communications equipment, software and services -- Part 3: Web content JIS X 8341-3:2010” which was enacted in August 2008 as the Japanese version of WCAG2.0.

OKI will be working on improving the website usability for all visitor's, including people with disabilities and older people.
