The Standard Guidelines for Promoting a Digital Society (デジタル社会推進標準ガイドライン) , set forth by the Digital Agency of Japan, are a cornerstone of Japan’s digital transformation efforts, starting from the governmental level. These guidelines provide the most up-to-date framework for ensuring efficiency, security, and inclusivity in digital services. While the guidelines are primarily focused on public sector regulations, they are still valuable to businesses operating or wishing to expand in Japan as a model for standards and norms—particularly in accessibility. Below, we’ve laid out a summary of the key accessibility-related areas from section DS-600 of the guidelines to help businesses stay in the know on an area that often goes overlooked in design.
Here’s what you need to know:
Summary of Key Sections
DS-670.1: Usability Guidelines
Purpose
Enhance user-centered, safe, and effective government information systems and UIs.
Objective
Assist government ministries and agencies in delivering digital services that minimize human error and mental burden and reduce support costs.
Key Requirements

DS-671.1: Introduction to Usability
Purpose
Serves as a practical companion to DS-670.1, focusing on human-centered design and safety engineering.
Core Concepts
- Psychology of Use: How context, proficiency, and cognitive biases affect usability.
- Design Principles: Focus on Accessibility First, Dialogue Principles (learnability, controllability, error management), Information Presentation, and Human-Centered Principles for AI systems.
Evaluation and Process
- Double V-Model: Tests design before implementation to avoid costly corrections.
- Qualitative Evaluation: Usability testing, expert heuristic evaluations, and cognitive walkthroughs recommended.
Safety Engineering
- Error Analysis: Uses models like STAMP/STPA for structural error analysis.
- Safety Culture: Promotes reporting near-miss incidents without fear of blame.
DS-671.2: Introduction to Web Accessibility
Purpose
A foundational resource for universal access to web-based information and services based on Japanese Industrial Standards (JIS).
Standards and Goals
- JIS X 8341-3:2016: Aligns with WCAG 2.0; but recommends deferrence WCAG 2.1/2.2 for more modern device support.
- Target Level: Level AA Compliance expected for public institutions.
Essential Checkpoints
- Critical: Prevents auto-playing audio, keyboard traps, and flashing hazards.
- Mandatory: Requires Alt Text, keyboard operation, logical reading orders, and a contrast ratio of at least 4.5:1.
Implementation Lifecycle
- Procurement: Accessibility included in RFPs.
- Step-by-Step Testing: Conducts testing through various stages, ending with formal JIS testing.
- Special Media: Guidelines for accessible PDFs and video captioning/sign language.
DS-672.1: Web Accessibility Guide for Public Relations
Purpose
A practical guidebook for PR officials to ensure videos and social media content are accessible.
Focus on Multimedia
Detailed instructions on accessibility features like closed captions, sign language translation, audio guides, and written transcripts.
Social Media (SNS) Strategy
Instructions for accessibility across platforms such as adding alt-text and managing auto-generated captions.
Planning and Procurement
Encourages considering accessibility in the planning phase and includes accessibility requirements in procurement contracts.
Inclusive Design
Addresses needs of users with visual or hearing impairments, emphasizing high color contrast and avoiding high-frequency flashing.
Comparison to WCAG
Fortunately, the DS Guidelines do not differ much in standards and best practices laid out by the Web Content Accessibility Guidelines (WCAG) or the General Data Protection Regulation (GDPR) and often reference them directly. While WCAG focuses on the accessibility of web content, the Japanese guidelines expand accessibility principles beyond digital interfaces to include service designs and government application processes more broadly. This emphasis means that businesses must not only ensure their websites comply with accessibility standards but also that the overall operational practices are inclusive. Nevertheless, some parts of the guidelines are not up to date with WCAG 2.2 . For areas not covered, like aspects of more modern smartphones, the guidelines recommend referring to the latest WCAG version.
Japan-Specific Differences
While guidelines and standards in Japan are similar and are often updated in response to advancements in the US or EU, there are a few differences in The Digital Guidelines that relate to accessibility. One is laid out in JIS X 8341‑3, referenced in the guidelines, related to accessibility with Japan‑specific test items such as ruby/furigana, vertical text, IME input, pronunciation/TTS hints, and Japanese PDF tagging. These guidances usually require Japanese‑language deliverables, detailed exit/hand‑over clauses, and may mandate domestic hosting or accredited cloud providers for more sensitive systems.

Recommendations for Digital Compliance and Design Considerations
Prioritize International Regulations
Ensure products are first WCAG/GDPR-compliant and accessible.
Understand Local Regulations
Learn Japanese digital laws and guidelines on cultural differences like language.
Foster Partnerships
Consider strategic collaboration with local government and businesses familiar with best practices.
Though the guidelines are first and foremost intended for the public sector, the practices and standards are a good benchmark for private sector digital ecosystems to strive for. By adhering to these guidelines, your business will not only ensure compliance but also embrace practices that foster a comprehensive and robust digital transformation. This approach not only facilitates smoother entry into the Japanese market but also enhances the global competitiveness of your offerings.
Connecting Guidelines to Usable Services: What UX Research Reveals
Adhering to the guidelines can improve chances of success in the Japanese market. However, compliance does not guarantee a service that is easy to use for everyone.
This is where UX research becomes important to validate usability.
In UX research, we observe how actual users interact with a service, uncovering issues that designers and developers might overlook.
For example, usability tests can help identify:
- Where users got confused
- What actions they attempted
- Where they gave up
- Whether they could recover from errors
- What anxieties or stress they experienced
Furthermore, by involving lead users who regularly use assistive technologies such as screen readers, voice input, or screen magnification, we can discover improvements not apparent through guideline compliance alone. Addressing accessibility should not be a one-time check. It is crucial to continuously evaluate and improve in response to new features, changing user environments, and user diversity. By conducting UX research within this improvement cycle, we can prioritize based on user feedback and real actions, leading to more effective enhancements and a service as enjoyable as it is usable.
Retrofitting digital tools and services to meet standards is an increasingly common practice, especially with the rise of AI. Through retrofitting however, previously used operation paths may become inaccessible or the retro-fitted accessible functions could be more stress-inducing or unintuitive to users. Incorporating lead users to test pathways and tasks using assistive functions is but one way UX testing aids in accurate, effective inclusive design. Combining compliance with usability transforms accessibility efforts from merely meeting standards to an ongoing initiative for quality improvement that delivers value to users, and the business.
