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