Target and current state

This site aims at WCAG 2.2 level AA. Page content and navigation are present in the HTML, so every record stays readable with JavaScript disabled; only search and filtering need it. Fonts are served from this site and do not depend on external services.

Not yet tested

The following have been checked page by page at widths from 320 to 1600 pixels, and again with text scaled to 200%: horizontal overflow, elements exceeding the viewport, clipped text, heading levels, language attributes on foreign-language fragments, accessible names on focusable elements, focus outlines, the skip link, and the contrast of body and large text. Some things automated checks cannot cover, and these have not been checked on real devices yet: how browsers actually render the pages, screen-reader reading order, and what the complete keyboard path actually feels like. The Japanese interface prefers fonts already installed on your device, so appearance may differ between systems. Please report problems through the corrections channel.

No accessibility overlays

This site does not use accessibility overlays or automatic remediation scripts. Such tools often interfere with a reader’s own assistive technology, so we prefer to fix the pages themselves.

Contact details and the handling process are on the corrections page.
