How we measured this
Japan readings on this page come from RealUptime's own Tokyo probe against O2's public endpoints. They are not user reports, and they are not O2's own status page.
See O2's full check readings, the 90-day history by region, or the outage tracker methodology.
Japan readings here are taken from that country and show the time of the last one, but O2 has not yet accumulated enough continuous history for us to publish this page to search engines.
