Efforts for Accessibility

This site is being created based on the "Japan Industrial Standard (JIS) X8341-3: Guideline for Older Persons and Persons with Disabilities Information and Communications Equipment, Software, and Services Part 3: Web Content" (enacted on June 20, 2004). Efforts are being made to create a web site which is easy to use for everyone: older persons, persons with disabilities or temporary disabilities, and persons who have certain limitations in using web sites.

We are creating the web site based on the following.

  • Each page has a title, so that the contents are clearly understandable.
  • Characters defined by the JIS, ISO, and New-JIS standard are used, and "platform dependent characters," which are not displayed correctly unless displayed on specific machines or specific environments, will not be used.
  • In order to allow users to easily find the information they are looking for, the locations and display style of the basic operating components for navigation (menus) are consistent.
  • Expression which relies only on differences in the colors of characters and images is avoided.
  • Concerning charts, etc., alternative information is provided in the text, as much as possible. Concerning photographs, etc. which are difficult to explain, a description to the effect that charts, photos, and flowcharts, etc. are present is provided using the alt attribute.
  • Line-breaks and spaces added for improved visual appearance will not be inserted in the middle of words.
  • Browsers which do not support frame functions, and “frame functions” which are difficult to understand for screen reader users are not used.
  • To avoid confusion, there is no automatic redirection to different pages or automatic renewal of the contents of the displayed page.

Regarding the Style Sheet

In consideration of accessibility, almost all HTML documents are structured on this web site, and CSS (Cascading Style Sheets) is also adopted, to set the document layout and other elements of visual appearance apart from document structure.

By so doing, HTML source code is clearly documented, and screen readers can be used more easily.

Considerations are given to ensure that, for users of browsers which do not support style sheets, or when style sheets may be supported, but are not in use, interference with the acquisition of information is avoided as much as possible.

Voice Browser

The greatest possible care is being taken regarding the following issues, to ensure that the contents are understandable when presented by voice.

We are endeavoring to ensure the following. If you have any trouble accessing our web pages, please contact us via e-mail, etc.

Times are written in the form, 10 am/pm, rather than 10:00 (ten-zero-zero).
Dates are written in the form, "January 1, Heisei 16 (Heisei-sixteen-January-first)", rather than "H16.1.1.(H-sixteen-one-one)."
Days of the week
Days of the week are written in the form, "Monday (Getsuyobi)" or "Tuesday (Kayobi)", rather "Mon (Tsuki)" or "Tue (Hi)."
The alt attribute is provided, by which alternative text is specified to accurately convey the image meaning. Arrangement is made in a manner so that images which are considered to be unnecessary as information can be skipped.

Arrangement is made in a manner so that the reading order is considered, and navigation menus can be skipped to avoid common navigation components from being read repeatedly.

Change of Character Size

Changing the size of the display characters is possible.

For users who feel that the characters are difficult to read, text sizes may easily be adjusted, using the browser functions for magnifying or shrinking the text sizes. Text rather than images will be used for titles, as much as possible.


Plugins are external software to extend the functionality of software (browser) which does not have the function as a standard. By installing the following plugin software, the contents provided by this web site can be used more effectively, with improved convenience.
