Technical Standard
What is JIS X 8341-3?
JIS X 8341-3 is Japan's official web accessibility standard, published by the Japanese Industrial Standards (JIS) committee. It defines accessibility requirements for web content to ensure usability for people with disabilities.
The standard is largely based on the Web Content Accessibility Guidelines (WCAG 2.0), aligning with its principles and success criteria. The latest version was published in 2016 and is widely used across government and public sector websites in Japan.
Legal Foundation
Legal Framework Supporting Accessibility in Japan
Several laws support digital accessibility expectations in Japan.
Basic Act for Persons with Disabilities
The Basic Act for Persons with Disabilities promotes social inclusion and accessibility across society.
The Act encourages equal participation of people with disabilities in public life, including access to digital information.
Act on the Elimination of Discrimination against Persons with Disabilities
The Act on the Elimination of Discrimination against Persons with Disabilities took effect in 2016.
The law requires:
- Government organisations to provide reasonable accommodation
- Businesses to avoid discriminatory practices
In 2024, amendments strengthened expectations for private businesses to provide reasonable accommodations, increasing accessibility expectations for digital services.

Government procurement projects often require JIS accessibility conformance, and private companies increasingly adopt the standard to align with inclusive design practices and reduce discrimination risk.
Conformance Levels
JIS X 8341-3 Conformance Levels
JIS accessibility conformance is structured similarly to WCAG, with three defined levels:
Level A
Basic accessibility requirements that remove major barriers.
Level AA
Recommended accessibility level and the most commonly adopted target for public sector websites.
Level AAA
Highest level of accessibility, often difficult to achieve across large websites.
Most organizations target Level AA conformance, the level required for public sector websites and recommended for private organizations.
WCAG Alignment
