How Can We Help?

Quotes are processed within 1 business day (Mon–Fri). Urgent processing is available as a paid option.

Bank transfer is currently the only available payment method. We plan to support credit cards, cryptocurrency, and PayPal in the future. Please check your invoice or payment page for the latest available payment methods.

Yes! Mercari is one of our most popular platforms. We charge a 20% service fee (minimum $15.00 USD) for C2C marketplace purchases (Mercari, Yahoo Auctions, etc.). The fee applies to each order number individually. See our pricing page for details.

If an item becomes unavailable after your quote, we will notify you promptly. We will offer alternatives or process a refund of the amount paid, minus any service fees and expenses already incurred. See our Cancellation, Return and Refund Policy for details.

The free storage period depends on your plan. The specific deadline is shown in your dashboard and on our pricing page. After the free period, daily storage fees apply. We will try to notify you before charges begin, but we cannot guarantee delivery of notifications — please monitor your own deadline in your dashboard. See our Shipping and Storage Policy for details.

Yes! You can submit multiple items at once. After submission, each item receives its own separate order number — quotes, invoices, and service fees are processed individually per order number. Our consolidation service can then combine multiple packages into one shipment to save on shipping costs.

JapanCart is a purchasing agent, not a direct seller. Whether a return is possible depends on the shop's return policy. C2C marketplace items (Mercari, Yahoo Auctions, etc.) are generally non-returnable. If you wish to request a return, please contact us. Domestic return shipping and repackaging costs are the customer's responsibility. Service fees and transaction charges already incurred are non-refundable. See our Cancellation, Return and Refund Policy for details.

If you would like insurance coverage, please request it before shipment. Insurance premiums are charged separately. Coverage may not be available for all shipments depending on the carrier and policy terms. In the event of loss or damage, we will assist with the carrier's claims process. See our Shipping and Storage Policy for details.
