Japanese Flea Market Survival Guide for Foreigners
Mercari, Yahoo Auctions & Rakuma — the unwritten rules, required phrases, common mistakes, and how to avoid getting blocked or reported.
The Unwritten Rules of Japanese Flea Markets
- Always send a greeting message when you buy. In Japan, sending a brief 挨拶 (greeting) after purchasing is standard etiquette — skipping it feels rude to many sellers.
- Response time matters. Buyers and sellers expect replies within a few hours, not days. Taking too long without notice may result in a bad review or cancellation.
- Know the difference between 即購入OK and コメント必須. Some sellers require you to comment before buying (コメント必須). Others explicitly allow immediate purchase (即購入OK). Violating this unspoken rule is a fast way to get negative feedback.
- Never negotiate aggressively. Making very low offers or pushing back multiple times after a refusal is considered rude. One polite attempt is acceptable.
- Pack carefully. Poor packaging that results in damage almost always leads to a bad review, even if shipping was handled by a third party.

Common Mistakes Foreigners Make
- Ignoring messages too long. No response for 24+ hours without explanation is often reported as unresponsive — this can lead to forced cancellations.
- Writing English-only descriptions. Most Mercari buyers are Japanese. An English-only listing dramatically limits your audience.
- Pricing above market rate. Japanese flea market buyers are price-conscious and can compare easily. Listings priced too high simply don't sell.
- Not understanding 取り置き (reservation holds). Some buyers will ask you to hold an item temporarily. This is a common but informal practice — you're under no obligation, but refusing politely is better than ignoring.
- Leaving harsh reviews over minor issues. Negative reviews escalate quickly and hurt your seller rating. Reserve them for genuine problems.
Understanding Japanese Shipping Options
One advantage of selling in Japan: shipping is extremely convenient. You don't need home pickup for most services.
- らくらくメルカリ便 / ゆうゆうメルカリ便: Mercari's partnered shipping services. Anonymous (address hidden from buyers), tracked, and priced by size. Drop off at convenience stores or post offices.
- Convenience store drop-off: 7-Eleven (ゆうゆう便 uses post offices), FamilyMart and Lawson accept らくらく便 via Yamato Transport. Scan the QR code from the app and you're done.
- No home pickup required for most standard Mercari services — you go to the store, not the other way around.

Tax Rules for Foreign Sellers
- Under ¥200,000 profit/year: If you are a salaried worker in Japan, you generally don't need to file a tax return for flea market income below this threshold.
- Over ¥200,000: You need to file a確定申告 (tax return) even as a foreigner, as long as you're a resident in Japan for tax purposes.
- Personal goods exemption: Selling your own used personal belongings (clothes, household items) is generally tax-free regardless of amount — this is called the 生活用動産 exemption.
