- The Tokyo Metropolitan Government reported it is monitoring systems through its Cybersecurity Center, applying patches, and temporarily stopping some citizen-facing services while no damage has been confirmed.
- Shiga Prefecture suspended 69 web systems, including some school sites, as a precaution and restored search and library services on Oct. 22 after safety checks.
- Mie Prefecture took 26 sites offline, including its library search and a public-records file index, and said no information leaks have been found as it sequentially reopens services after verification.
