This text provides an overview of common password patterns in Japan, recent security trends, and best practices for creating secure, localized credentials. Common Japanese Password Patterns
Research on Japanese Mnemonic Passwords suggests that users can create 14–18 character passwords by remembering a simple 6–8 character Japanese sentence and two numbers, significantly increasing security without losing memorability.

Credential Stuffing: Increased attacks on Japanese e-commerce sites using leaked lists from global breaches. This text provides an overview of common password
- Includes most commonly used weak passwords in Japan: numeric patterns, kana/kanji names, common phrases, keyboard patterns, year-based passwords, Japanese-English hybrids, and popular service names.
- Each entry annotated with why it's weak (e.g., predictable, short, derived from public data).
- Versioned and timestamped; accessible read-only by UI components.
Breach and leak cross-check (privacy-preserving) current common password trends
Recent studies on the characteristics of Japanese user-created passwords reveal unique linguistic and cultural patterns that distinguish them from those in other language spheres. This paper outlines the findings from recent analyses of leaked Japanese password datasets, current common password trends, and strategic shifts toward passwordless authentication in Japan. 1. Unique Characteristics of Japanese Passwords
- Analyze the list for common patterns (lengths, character sets, keyboard patterns, repeated strings).
- Identify top 100 most common passwords and their frequencies.
- Categorize by language/script (kana, kanji, romaji, alphanumeric).
- Highlight risky passwords and password-strength distribution.
- Provide recommendations for password policy and user education.
- Include sample regexes to detect weak passwords and suggested banned-password rules.
- Give brief methodology and caveats about dataset bias.
