Mercari is a C2C marketplace app allowing anyone with a smartphone to easily sell items they no longer need, providing a new and unique user experience. In the past, buying and selling secondhand items has commonly been done at physical shops. However, this came with issues: the travel time required to go to these shops, the limited selection of items these shops carry, the unclear prices for both the buyer and seller alike due to the involvement of dealers, and more. Online auction websites for buying and selling secondhand items came with their own problems, including difficult listing procedures and long bidding times. On Mercari, anyone can use their smartphone to easily buy and sell items. We also provide easy and inexpensive shipping options thanks to our partnerships with delivery companies and convenience stores. As our service is catered to individuals on both the buying and selling sides, anyone can experience the fun of easily selling unneeded items for money and the excitement of finding unique secondhand items to buy. With the technological capabilities and extensive user and information bases built through Mercari, we launched the Merpay mobile payment service in 2019, the B2C marketplace Mercari Shops in October 2021, and the cryptoasset exchange service Mercoin in March 2023. We strive to continuously enhance the user experience and expand our businesses.
