JIS X 8341-3:2016

What it is

JIS X 8341-3:2016 is the Japanese Industrial Standard for web content accessibility, technically equivalent to ISO/IEC 40500:2012 (WCAG 2.0). The Web Accessibility Infrastructure Committee (WAIC) maintains the testing methodology and conformance reports.

Why it matters

The Ministry of Internal Affairs and Communications recommends that public-sector websites comply with JIS X 8341-3 at the AA level. While not strictly binding on the private sector, it's the de facto procurement and audit benchmark for any Japanese-facing digital service.

Who it applies to

Japan — required for national and local government public-facing websites; recommended for the private sector.

• Site types: Government, Education, Corporate / B2B, E-commerce
• Jurisdictions: Other / unknown
