About Japan Post
Japan Post is the national carrier responsible for mail delivery, international shipping, and logistics within Japan. Customers use the website for domestic parcel tracking, requesting redelivery, and calculating postage rates for international EMS shipments. Technical failures typically result in the tracking system being unavailable or the postal code lookup tool returning errors. Rimetry observes the responsiveness of these logistics portals from different network paths to help you determine if the tracking database is currently reachable for users inside and outside of Japan.
Problems with Japan Post can affect parcel tracking, website, notifications independently.
Japan Post (japanpost.jp) is a delivery & logistics service monitored continuously by rimetry's automated checks. We probe its public endpoints every 60 seconds in repeated independent rounds to detect outages and latency spikes the moment they happen.
Right now Japan Post is reporting as operational across our probes, with an average response time of 2476 ms and 100.00% uptime over the last 24 hours. Most users connecting to japanpost.jp are seeing it work normally.
