How we measured this
Japan readings on this page come from RealUptime's own Tokyo probe against Mastodon's public endpoints. They are not user reports, and they are not Mastodon's own status page.
See Mastodon'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 Mastodon has not yet accumulated enough continuous history for us to publish this page to search engines.
