Thanks for raising this.

Japan Wi-Fi Channel Regulations (MIC, 2025):

• 5GHz band

  • 20 MHz: Channels 36–64, 100–144
  • 40 MHz: Channels 38, 46, 54, 62, 102–134, 142
  • 80 MHz: Channels 42, 58, 106, 122, 138
  • 160 MHz: Channels 50, 114
  • 320 MHz: Not permitted (and WiFiAnalyzer already does not show 320 MHz here)

• 6GHz band

  • 20 MHz: Channels 1–93
  • 40 MHz: Channels 3–91
  • 80 MHz: Channels 7–87
  • 160 MHz: Channels 15, 47, 79
  • 320 MHz: Not currently permitted in Japan, but included in WiFiAnalyzer for future compatibility so the codebase doesn’t need constant changes

Important clarification:
WiFiAnalyzer does not control router settings. The channel list shown in the app is a recommendation/reference only. Actual enforcement of allowed channels per country is handled by the router firmware and regulatory domain settings.

Next release of application will update its Japan profile, while keeping the 6GHz 320 MHz entries for forward compatibility.

Thank you for maintenance and management of the WiFiAnalizer, and reply.

Sorry, there was a typo in my post, I'll correct it just in case:

5GHz

• 40MHz: 38, 46, 54, 62, 102, 110, 118, 126, 134, 142

I'm looking forward to the next release!
