How to Handle Returns & Disputes on Mercari Japan as a Foreigner [2026]
By Furima Navi Team • May 26, 2026 • 10 min read
Quick Answer
If you have a problem on Mercari Japan, do NOT rate the transaction. Go to the transaction page, tap the item, and use the Help Center to file a report. Include photos, your order ID (商品ID), and a clear description. Mercari support responds within 1–3 days.
The Golden Rule: Do Not Rate Until Satisfied
Once you tap 良かった (Good) or 残念だった (Disappointing), the transaction is permanently closed. Mercari support options drop dramatically after rating.
Always inspect the item fully before rating. If there is ANY issue — do not rate. Go to the Help Center first.
