Shipping policy

Last updated: 8 November 2026

Where we deliver

We deliver across Japan, including all 47 prefectures. We do not offer international shipping. If a particular address cannot be served by the available carrier, we will contact you before dispatch to discuss the options. For questions about an address, contact cs@duatech.jp before placing an order.

Shipping charges

For delivery within Japan, shipping is free on all orders, regardless of order value. We do not charge customers an additional cash-on-delivery fee when that payment method is available for the order. The shipping method, charges, and order total are shown before the order is submitted.

Processing and delivery time

Every day, including weekends and Japanese public holidays, we aim to hand orders received before 4:00 p.m. Japan time to Japan Post on the same day. Orders received at or after 4:00 p.m. are scheduled for dispatch the following day. After Japan Post accepts the parcel, delivery is estimated at approximately one day for Honshu and two days for destinations outside Honshu. These are estimates, not guaranteed arrival dates. The actual timing depends on the destination, acceptance time, weather, and transport conditions. We will contact you if dispatch is delayed.

Address changes and delivery problems

Please check your delivery address and contact details before submitting the order. If you need to correct them, email cs@duatech.jp with your order number as soon as possible. Once a parcel has been handed to Japan Post, changes may not be possible. If a delivery fails or the parcel is returned to us, please contact cs@duatech.jp so we can discuss the next step.

For a damaged, missing, or incorrect delivery, contact cs@duatech.jp with your order number and a description of the issue.
