Mercari launches a vetted marketplace for authenticated luxury goods and refurbished electronics
Mercari launched m department, a standalone marketplace for professionally vetted secondhand luxury goods and refurbished electronics, on 14 July with 88 merchants at launch — a 'third market' between new and open peer-to-peer resale that puts Japan's dominant flea-market app into more direct competition with the authentication-led resale specialists it once bypassed.

Mercari launched "m department," a new marketplace for professionally vetted secondhand luxury goods and refurbished electronics, on 14 July, running as a standalone e-commerce site separate from the main Mercari app, according to the company. 88 merchants joined at launch.
Every seller on m department has been vetted rather than open to the general public, Mercari said, and every item passes through a specialist before listing: refurbished smartphones, tablets, laptops and cameras are inspected, repaired, cleaned, battery-tested and wiped of prior data, carrying a 180-day operating guarantee, while bags, watches, jewellery, clothing and shoes are authenticated by certified appraisers to screen out counterfeits. Return windows run from 7 to 30 days for electronics depending on category and 10 days for luxury goods, the company said.
Mercari is positioning the service as a "third market" sitting between buying new and the open peer-to-peer resale its own flagship app runs. The company said its own research found roughly seven in ten consumers hesitate to buy high-value used goods over authenticity and working-order concerns — the exact anxiety a curated, guaranteed channel is built to remove. Citing separate market forecasts, it noted the refurbished-smartphone category alone could reach roughly $99.4 billion worldwide by 2033.
The interesting part is that Mercari is choosing not to run this on Mercari. Its core app is built on open listing and buyer-beware pricing — the model that made it Japan's dominant resale platform — so a second, vetted, appraiser-backed site is an admission that trust, not price, is what still keeps some shoppers out of secondhand luxury and premium electronics. It puts Mercari in more direct competition with the authentication-led specialists — pawnshops, luxury resale chains — that built their businesses on exactly that trust gap, rather than with the flea-market listings that made Mercari itself.
