In 2013, founder Shintaro Yamada, inspired by challenges encountered during a world tour, created the flea market app 'Mercari'.
Founded Mercari Inc.
Establishment
Since February 2019, registration of sellers' personal information (address, name, date of birth) has been mandatory during new member sign-up. By ensuring that the registered name matches the bank account used for payouts, we prevent fraudulent listings such as stolen goods.
On October 9, 2025, Mercari released a press release announcing a white paper on the 'Basic Principles of the Marketplace' and newly established response policies.
Mercari Inc. will hold the "Mercari Green Friday Project 2026 ~REUSE ACTIONS!~" at TENOHA Daikanyama from November 20 to 22, 2026. The event will allow participants to experience bartering, purchasing and repairing reused items in collaboration with eight companies, and will calculate the CO2 reduction contribution per garment using the AI-LCA technology developed by the R4D research and development organization, distributing the results as stickers.
From November 26 to 29, 2026, Mercari will hold an immersive experience event "Our Family Home – Let’s Revisit Everyone’s Return Home" in Harajuku, Tokyo. The exhibition, recreating a Heisei-era "children’s room," allows visitors to discover the value of objects and offers a listing experience utilizing the latest AI. Research revealed that about 60% of the younger generation who have left their family homes leave personal belongings behind, while more than 70% of the older generation hesitate to discard their children’s personal items.
Mercari announced that cross-border transactions in China, Taiwan, and Hong Kong increased by 15.5% compared to the previous period ahead of W11 (Singles' Day) on November 11. The largest transaction volume accounted for 68.7% in China, with popular content transactions becoming more active.
Mercari held the immersive experience event "Someone's Favorite Room Exhibition" in Harajuku from October 28 to November 1, 2026. Over 1,600 visitors attended over the five days, with about 20% coming from overseas. Attendees expressed surprise at the overseas popularity of familiar items, empathy with fans who share the same "likes," and interest in Mercari's cross-border transactions.
The cumulative number of registered users of the Mercari Global App surpassed 1 million on August 28, 2026. With the expansion of usage, starting October 21, Mercari is gradually offering a '安心鑑定' service that evaluates items domestically before overseas shipment for users in the United States and Taiwan. In the future, Mercari plans to provide an 'Auction' feature, aiming to broaden the sense of security and options for overseas users when making purchases.
According to Mercari’s analysis, demand for wedding-related items rose as people prepared for the autumn wedding season, with transactions from August to October exceeding the monthly average for the past five years. Over the past year, transactions of “accessories” and “party dresses” increased by more than 30% year over year, while the average transaction price of wedding dresses rose by about 8% between September 2021 and August 2026.
Mercari has entered into a capital and business partnership agreement with Quick Network. The two companies will collaborate with "Winning Assessment Selca" to provide a touchpoint that makes it easier for Mercari users to understand the value of their cars and consider selling, and will work to create new value in used car sales.
Mercari will host the immersive experience event 'World's Someone's Favorite Room Exhibition' from October 28 to November 1, 2026, at WITH HARAJUKU in Tokyo's Harajuku. Based on Mercari's cross-border transaction record, the event recreates the rooms of fictional fans living in the United States, France, and Taiwan using items purchased on Mercari. It is an event where you can experience how Japanese pop culture is loved overseas and the circulation of value across borders.
For 14 days from October 1 through 14, 2026, Mercari will hold the Happy Mercari Market event for buyers and sellers. Five campaigns will support transactions through daily benefits, discounted shipping, coupons, points on sales fees, and a drawing for reusable packaging materials. Advance entry opens on the special website on September 24.
On September 17, 2026, Mercari, Inc. launched an in-app ‘Item Valuation’ feature that estimates the market value of household items from a photo. AI identifies the item from the image and helps users list it for sale. The feature requires the latest app version and is being rolled out gradually.
