Who This Is For

Your site serves the public and is expected to meet the accessibility requirements set by the Japanese government, which reference JIS X 8341-3 and WCAG 2.1 AA. National and municipal government websites, public health information portals, and services funded by public bodies all fall into this category. Compliance is an obligation, not an option, and the accessibility statement needs to be accurate.

Your organisation has committed to accessible digital services, either through internal policy or as part of a corporate social responsibility framework. Your website and internal tools have not been audited against JIS X 8341-3 or WCAG 2.1 AA. You need a formal audit with a documented remediation plan that you can present to internal stakeholders and use to track progress.

A user has reported that your website is not accessible. You have received a formal complaint, or your customer service team has fielded repeated contacts from users who cannot complete a key task. You need to understand the scope of the problem quickly, prioritise the fixes that will resolve the most serious barriers first, and document the work you have done.

/ What's broken

What's Broken

Your Japanese Text Is Not Rendering Accessibly

Japanese web accessibility includes requirements that do not exist for Latin-script sites. CJK characters require larger base font sizes than Latin text to remain legible at the same point size. Line height needs to be set correctly for vertical density of Japanese text. Character spacing (letter-spacing) that works for Latin alphabets can break kanji readability. Vertical writing mode, when used, requires its own accessibility considerations. Sites built without attention to these specifics will fail users with low vision even if the underlying structure passes WCAG criteria.

Your Dynamic Content Is Not Announced to Screen Reader Users

Modern Japanese websites commonly use carousels, tabs, accordion menus, modal dialogues, and dynamic search results. When these components are built without correct ARIA roles and live region announcements, screen reader users receive no notification that content has changed. PC-Talker, NVDA with Japanese voice, and VoiceOver on iOS all behave differently around dynamic content, and a component that appears to work with one may fail with another.

Your Keyboard Navigation Has Never Been Tested

Keyboard-only navigation is used by people with motor disabilities, by power users, and by anyone navigating a form-heavy site efficiently. Custom navigation menus built with JavaScript, interactive product filters, and multi-step forms are all areas where keyboard accessibility commonly breaks. If your site has never been tested with Tab, Shift-Tab, Enter, Space, and arrow keys only, you do not know whether it is keyboard-operable.

Your Mobile Layout Has Problems at Non-Standard Screen Widths

Japanese smartphone usage is high, and the range of Android devices in use in Japan covers a wider spread of screen sizes and densities than in many Western markets. A responsive layout tested only on an iPhone and a standard Android breakpoint will have failures on mid-range viewports, fold phones, and tablets. Touch target sizes that pass on a high-density screen may fail on a lower-density device at the same physical size.

/ What we engineer

What We Do

Automated Accessibility Scan

We run a full automated scan using Axe and WAVE across every page type in your site. We document findings, classify them by WCAG 2.1 criterion and corresponding JIS X 8341-3 clause, and identify structural patterns so that a single fix resolves multiple instances of the same failure type.

Japanese Screen Reader Testing

We test with PC-Talker (the most widely used screen reader in Japan), NVDA with Japanese voice synthesis, and VoiceOver on iOS. We test heading structure navigation, landmark navigation, link text quality, form label associations, error message announcements, and the behaviour of all dynamic components. We document findings in both Japanese and English.

Keyboard Navigation Audit

We test every interactive element using keyboard only. We check focus indicator visibility, tab order logic, custom component keyboard interaction patterns, focus management in modals and dynamic content, and the presence and functionality of skip navigation links. We test against the keyboard interaction patterns specified in the ARIA Authoring Practices Guide.

CJK Text Rendering and Readability Audit

We audit your typography for accessibility-specific Japanese text requirements: base font size in px and rem units, line height relative to font size for Japanese character density, character spacing for kanji and kana readability, and the correct use of font-feature-settings for CJK glyphs. We provide specific CSS recommendations rather than general guidance.

Colour Contrast Report

We test all text and graphical elements against their backgrounds for WCAG 2.1 AA contrast compliance. We provide current contrast ratio, required ratio, and a recommended compliant value that preserves your design intent. We pay particular attention to Japanese interface patterns where light grey text on white backgrounds is common and frequently fails contrast requirements.

ARIA Implementation Review

We review all ARIA usage across your site. We identify incorrect role assignments, missing required ARIA properties, unsupported ARIA patterns, and cases where native HTML elements would be more appropriate than ARIA-augmented custom components. We also review live region implementation for dynamic content updates.

Responsive Layout Audit and Retest Confirmation

We test across viewport widths from 320px to 1920px and on real iOS and Android devices representative of the Japanese market. We fix layout failures and retest. We deliver an audit report in Japanese and English classifying all issues as critical, major, or minor, and a retest confirmation report after remediation.

/ How it works

Process

Scope and Discovery

We review your site architecture, identify all page types and interaction patterns requiring testing, and agree the audit scope. We confirm whether JIS X 8341-3 level AA or WCAG 2.1 AA is the operative standard, whether bilingual documentation is required, and whether there are any procurement or regulatory deadlines to work to. This takes two to three days.
Automated Scan and Manual Audit

We run the automated scan and conduct the manual audit in parallel: Japanese screen reader testing, keyboard navigation, CJK text rendering review, colour contrast analysis, ARIA review, and responsive layout testing across the device range relevant to your Japanese user base. The audit takes one to two weeks depending on site complexity.
Audit Report Delivery

We deliver the bilingual accessibility audit report, classified by severity and WCAG/JIS criterion, with specific remediation recommendations. We present findings in Japanese to your team and answer questions before remediation begins.
Remediation and Retest

We implement fixes or support your development team in implementing them. After remediation, we run the full retest and issue the bilingual retest confirmation report. This report supports your accessibility declaration and any procurement documentation.

FAQ

Straight answers on scope, timelines and cost. Anything else, ask us directly.

Ask us directly

What is JIS X 8341-3 and how does it relate to WCAG 2.1?

JIS X 8341-3 is the Japanese Industrial Standard for the accessibility of web content, developed by the Japanese Standards Association in alignment with WCAG. The current version references WCAG 2.1 success criteria directly, with Japanese-language commentary and guidance. For most practical purposes, meeting WCAG 2.1 AA means meeting JIS X 8341-3 level AA. The primary distinction is that JIS X 8341-3 documentation is in Japanese and is the standard cited in Japanese government guidelines and procurement specifications. We test against both and report against both in the audit documentation.

Which screen readers do Japanese users with visual impairments actually use?

PC-Talker, developed by Nihon Supan, is the most widely used screen reader in Japan and uses NaturalReader AI or the bundled Japanese voice synthesiser. NVDA with Japanese voice support is also used, particularly among younger users and those familiar with the NVDA international community. On iOS, VoiceOver with Japanese language is common. We test with PC-Talker and NVDA with Japanese voice as the primary test tools, with VoiceOver on iOS for mobile testing.

What are the specific accessibility requirements for Japanese text rendering?

Japanese text accessibility differs from Latin-script accessibility in several areas. Base font size should typically be no smaller than 16px for body text, and often larger for kanji-heavy content. Line height for Japanese body text is typically 1.7 to 2.0 rather than the 1.5 common for Latin text, due to the visual density of CJK characters. Character spacing should not be reduced below 0.1em for body text. Font choice affects glyph rendering across operating systems, and the use of system fonts versus web fonts has accessibility implications for CJK character sets. We review all of these in the CJK text rendering audit.

How long does a JIS X 8341-3 audit take?

A full audit of a website with ten to twenty distinct page types typically takes two to three weeks from scope agreement to report delivery. Bilingual reporting adds approximately two to three days. Remediation time depends on the volume and severity of issues found. A site with typical Japanese enterprise accessibility debt, which commonly includes screen reader failures in dynamic components and CJK text rendering issues, takes four to eight weeks from audit report to retest confirmation.

Do you deliver audit reports in Japanese?

Yes. We deliver all audit reports in Japanese and English. The Japanese version is intended for your internal technical and compliance teams. The English version supports communication with international partners, parent companies, or global accessibility programmes. Both versions contain identical findings and recommendations; neither is a translation summary of the other.
