International EMS, Registered Airmail, and ePacket use the UPU format (2 letters + 9 digits + "JP", such as EM123456789JP). Domestic Yu-Pack parcels and Kakitome registered mail use 11 or 12 numeric digits.
What does "引受" (Acceptance) mean on Japan Post tracking?
引受 (Hikiuke / Acceptance) indicates that the parcel or letter was accepted at the origin post office counter or received from the sender.
What does "Dispatch from outward office of exchange" mean?
Your international shipment has cleared Japanese export customs at an international exchange office (such as Tokyo International Post Office or Kansai Airport) and has been loaded onto a flight to the destination country.
How fast is Japan Post international EMS delivery?
Japan Post EMS is one of the fastest postal services in the world, usually delivering to North America, Europe, and Asia within 3 to 6 business days, subject to customs clearance.
What should I do if my Japan Post status shows "Held by customs"?
Held by customs (通関手続中) means the item is being inspected by customs authorities. In most cases, it clears within 1 to 3 days unless duty payments or additional invoices are requested.
Can I track inbound international mail arriving in Japan?
Yes. Any international registered mail or parcel sent to Japan from abroad (such as Taiwan Post, USPS, or Royal Mail) can be tracked on Japan Post once it arrives at Japanese customs.
