Japan Post has discontinued the international shipping method, ePacket, as of September 23, 2023.
As a result, the checkbox for ePacket cannot be selected, as it is not a shipping method available at the moment.
In the newest version of easyRates, there are no checkboxes at all for ePacket.
As of March 3rd, 2025, Japan Post has announced that they are bringing back ePacket light.
With this, easyRates has also brought back ePacket light for everyone to use.
