Japanese Password List Updated May 2026

In cybersecurity contexts, a “Japanese password list” usually refers to a curated set of commonly used passwords observed among Japanese-speaking users, or passwords that follow patterns typical for Japanese audiences (e.g., using romaji, common Japanese words, names, dates in Japanese format, or keyboard walks on a Japanese layout). An “updated” list implies it includes recent breaches or survey data (e.g., from 2023–2026).

Examples might include:

If you are looking for this information to secure your network, consider the following defense measures against these lists:

  • Mandatory Complexity: Enforce a policy requiring Kanji or Katakana inputs (if supported) or passphrases, which are harder to dictionary attack.
  • MFA: Multi-Factor Authentication renders password lists useless, as the password alone is insufficient for entry.

    • Disclaimer: This information is provided for educational and security defense purposes only. Using password lists to access systems you do not own or have explicit permission to test is illegal.
