Refund policy

Last updated: October 5, 2026

Asunite Technology Co., Ltd. ("we", "us") sells genuine, new industrial parts sourced in Japan. Many of the items we sell (for example UPS units and replacement batteries) are ordered from the manufacturer specifically for each customer. For this reason, our return policy is as follows.

1. Defective, damaged or incorrect items

  • If an item arrives defective (does not work out of the box), damaged in transit, or is not the item you ordered, contact us at sales@asunite.net within 30 days of delivery.
  • Please include your order number, photos of the item, the packaging and the shipping label, and a short description of the problem.
  • Once we confirm the issue, we will offer a replacement or a full refund (including the original shipping cost). We provide a prepaid return label or reimburse the return shipping cost.

2. Change-of-mind returns

  • Unused items in their original, unopened packaging may be returned within 14 days of delivery if you contact us first and we approve the return.
  • The buyer pays the return shipping cost. The original shipping cost and any import duties or taxes you paid are not refundable.
  • Items that have been opened, installed or used, and items marked "special order" or "made to order" on the product page, cannot be returned for change of mind.

3. Non-returnable items

Batteries that have been installed or charged, items damaged by incorrect installation or by use with an incompatible power supply or voltage, and items without their original packaging cannot be returned unless they were defective on arrival.

4. Order cancellation

You can cancel an order free of charge before it ships. After shipment, the return rules above apply.

5. How to return an item

Email sales@asunite.net with your order number before sending anything back. Items sent without an approved return request cannot be accepted. Approved returns are shipped to:
Asunite Technology Co., Ltd., 1105, 1-17-11 Higashi-Ikebukuro, Toshima-ku, Tokyo 170-0013, Japan

6. Refunds

We inspect returned items within 5 business days of receipt. Approved refunds are issued to the original payment method within 5–10 business days of approval. The time it takes the refund to appear depends on your card issuer or bank.

7. Warranty

Products are covered by the manufacturer's warranty as provided in Japan. If an item fails during the warranty period, contact us and we will help with the manufacturer's warranty process.
