Flea Market App

According to a survey by Japan's Ministry of Economy, Trade and Industry, the country's CtoC e-commerce (consumer-to-consumer electronic commerce) market has surpassed 2 trillion yen, with flea market apps at its core. Mercari boasts over 20 million monthly active users and has exceeded 3 billion cumulative listings. Rakuma's strength lies in its integration with Rakuten Points, while Yahoo! Flea Market has strong affinity with the PayPay ecosystem.

The revenue model for flea market apps centers on sales commissions - Mercari charges 10% of the sale price, while Rakuma charges 6%. Since commission rates directly impact seller profits, strategically choosing platforms based on product category and price range is effective. A practical approach is to list high-value items on Rakuma to minimize fees, while using Mercari's larger user base for everyday items where turnover speed matters most.

The most common transaction dispute on flea market apps is "discrepancy between the product description and the actual item." Sellers should honestly describe any scratches or stains and include photos taken from multiple angles - this is the foundation of building trust. Buyers should be cautious of sellers with few ratings or items priced far below market value, and develop the habit of checking profiles and past reviews before transacting.

Escrow payments (where the platform holds the payment temporarily and releases it to the seller after the buyer confirms receipt) have significantly reduced the risk of paying but never receiving the item. However, cases where buyers are pressured to confirm receipt quickly, or where sellers propose direct transactions outside the app, are likely scams. Always complete transactions within the app, and contact customer support if anything seems suspicious.
