The National Institute of Public Health Website is making ongoing efforts to enhance accessibility to ensure that all parties may acquire information without difficulty based on JIS X 8341-3 (Guidelines for older persons and persons with disabilities–Information and communications equipment, software, and services-Part 3: Web Content).

Use of Colors

The Website has been designed with color combinations that ensure the contrast of text and background colors to ensure the legibility of the text.

Text Font Size, etc.

Users are able to change font sizes.

Efforts have been made to ensure that platform-dependent characters (circled numbers and roman numerals, etc.) are not used. (Up to the second tier. Scheduled to successively handle third tier and higher.)

When using text decoration that significantly changes the meaning (such as strikethroughs), the meaning is also indicated in the text.

Composition of the Website

If Java script is not supported, substitute text links enable users to jump to the link destination.

Overall Requirements

An internal search function is available.

The site has been constructed to make the composition of the site easy to follow with a site map and navigation bar shared by all pages.


Each page is equipped with navigation that shares the same design as the landing page, and a breadcrumb list has been created to enhance user friendliness.

User Friendliness

Links to destinations within the same Website are displayed in the same window, and instances where a new window is opened have been minimized wherever possible.

The basic operation portions of the Website (links to the “top page” or “site map” or links within the page) use expressions (language / format / color / position, etc.) and functions that are consistent throughout the Website.

Links are displayed to indicate the content of the link destination.


Wherever possible, images are accompanied by an alt attribute that accurately indicates the content of the image (alternative information about the image).

When text is used in an image, the font, size, and contrast have been adjusted to ensure legibility.

If important information is explained using only an image, text that gives an overview of the information has been added as supplementary information (supplementary information about the image).
