The Short Answer

If your online order hasn’t been delivered, you can cancel the contract and request a full refund under Japan’s Act on Specified Commercial Transactions. You have until delivery is confirmed — or within 8 days after the scheduled delivery date — to cancel.

What the Law Says

Japan’s consumer protection law gives you clear rights when an online order fails to arrive. The Act on Specified Commercial Transactions applies to all online purchases and sets strict rules for delivery and cancellation.

Under Japanese law, sellers must deliver goods within the period they promised — or, if no period was specified, within 30 days of the order. If delivery is delayed beyond that, you may cancel the contract.

Once you cancel, the seller must refund the full purchase price (100%) without delay. They must also bear any return shipping costs if the item was already shipped but not received.

The seller must respond to your cancellation request within 7 days and complete the refund within a reasonable time — typically within a few business days after confirmation.

Statutory Text

If the business operator fails to deliver the goods within the agreed period or, if no period is agreed upon, within 30 days from the day following the day on which the contract was concluded, the consumer may cancel the contract.

What to Do

1

Check your order confirmation for the promised delivery date — if it has passed, you’re eligible to cancel.

2

Send a written cancellation notice to the seller (email is acceptable) citing Section 10 of the Act on Specified Commercial Transactions.

3

Keep proof of your notice (e.g., email timestamp or screenshot).

4

If the seller doesn’t respond within 7 days or refuses the refund, contact the Consumer Affairs Agency or file a complaint via their online portal.
