Every parcel is received and checked at our Tokyo warehouse before it ships internationally, and you pay shipping only after that check. You can add specific protections per order:
| Protection | Fee | What it covers |
|---|---|---|
| Empty-package verification | ¥20 | Staff confirm the seller's parcel is not empty; if it still arrives empty, item value is covered |
| Wrong or missing item inspection | ¥200 | Unboxing check against the listing; confirmed wrong/missing items are reimbursed |
| Unboxing photo service | ¥500 (basic) / ¥700 (premium) | Photos posted within 12 hours of arrival so you can see the item before it ships |
| Reinforcement | from ¥200 | Extra cushioning / box replacement for fragile and irregular items |
| Mercari Authentication | see checkout | Authenticity verification for items bought on Mercari |
Shipping cover: EMS includes free coverage up to ¥20,000; optional insurance is available for DHL and EMS (except EMS DDP to the US).
Refunds cover seller-side failures. Change-of-mind returns are not possible because every item is bought specifically for you.
| Situation | Outcome | Timing |
|---|---|---|
| Seller does not ship in time | Refund | 5–10 business days |
| Seller cancels | Automatic refund | 5–10 business days |
| Item proven counterfeit | Refund with valid authentication evidence; return shipping at your cost | Case by case |
| You no longer want an item already in the warehouse | No refund; you may forfeit it free of charge | — |
| Parcel arrives damaged | After-sales assistance; compensation up to the international shipping fee paid (carrier claim for Japan Post) | Report within 24 hours with photos and an unboxing video |
| Parcel lost in transit | OneMall confirms with the carrier and files the claim | Report when tracking is silent 48 hours after customs clearance |
| Returned by the carrier (wrong address, unpaid duties) | Original shipping not refunded; return fee may apply | — |
| Not shipped within the free storage window + 2 weeks of notices | Treated as abandoned, no refund | — |
OneMall is responsible for your item from the moment it arrives at the warehouse until it leaves. Payment methods: Visa, Mastercard (processed by Stripe) and PayPal; prices settle in USD.
Two things Trustpilot flags on our profile, stated plainly: we have not run review-invitation campaigns, so the sample is small, and we had not replied to negative reviews.
OneMall connects the major Japanese marketplaces in one account (Amazon Japan, Mercari, Rakuten, Rakuma, Suruga-ya, ZOZOTOWN, Yahoo! Auctions) and covers any other Japanese store through LinkBuy. The fee is flat per item and does not rise with the item price. For a side-by-side fee comparison with Buyee, ZenMarket and FROM JAPAN, see our fee comparison guide.
No. OneMall is operated by Inagora Inc. from a registered Tokyo address, holds a claimed Trustpilot profile rated 4.8/5 from 96 reviews (October 2026), and publishes its fees and refund rules on this page.

A flat ¥300 per item on Amazon Japan, Mercari, Rakuten, Rakuma, Suruga-ya and ZOZOTOWN; 3% (¥200–¥300) on Yahoo! Auctions; 5% (¥200–¥1,000) on LinkBuy orders. International shipping is charged separately after packing.
Not for change of mind, because each item is purchased specifically for you. You receive a refund if the seller does not ship or cancels, and may receive one for a proven counterfeit.
EMS includes coverage up to ¥20,000. Optional insurance is available for DHL and EMS (except EMS DDP to the US). Damage claims need photos and an unboxing video within 24 hours of delivery.
Yes. Since August 29, 2025 the US no longer applies the $800 de minimis exemption, so parcels from Japan to the US owe import duties based on the declared value and item type. The carrier collects them unless you choose a DDP option at checkout.
We have not run review-invitation campaigns on Trustpilot, so the sample is smaller. Read the individual reviews on Trustpilot and the 870 photo reviews on our Reviews page.
