Introduction

Circulate all forms of value to unleash the potential in all people

"What can I do to help society thrive with the finite resources we have?" The Mercari marketplace app was born in 2013 out of this thought by our founder Shintaro Yamada as he traveled the world. We believe that by circulating all forms of value, not just physical things and money, we can create opportunities for anyone to realize their dreams and contribute to society and the people around them. Mercari aims to use technology to connect people all over the world and create a world where anyone can unleash their potential.For more information about Mercari Group’s mission, see .

Equal Opportunity Hiring

Here at Mercari, we work to realize a world in which no one’s potential is limited by their background and everyone has the opportunity to freely create value. We also firmly believe that a mindset of Inclusion & Diversity is essential for us to achieve our mission.

This, of course, extends to our hiring practices as well. Mercari is committed to eliminating discrimination based on age, gender, sexual orientation, race, religion, physical disability, and other such factors so that anyone who shares our mission and values can join us, regardless of their background. For more details, please read our .

What We Do

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
