Introduction

Circulating all kinds of value and expanding everyone's potential

"What can we do to create a richer society in the face of limited earth resources?" In 2013, Mercari was born out of founder Shintaro Yamada's awareness of this issue during his world travels. We believe that by circulating all kinds of value, not just physical goods and money, we can enable everyone to achieve what they want to do and increase the options for contributing to society.

We will realize a world in which the potential of people all over the world can be fully realized by connecting people through the power of technology. Please see the Mercari Culture Doc for the guidelines that Mercari Group aims for.

Equal Opportunity in Recruitment

At Mercari, we strive to create a society where individuals have the opportunity to freely create value without being limited by their background. We believe that "Inclusion & Diversity" is essential to fulfilling Mercari's mission.

In our recruitment activities, we promise to eliminate all forms of discrimination based on age, gender, sexual orientation, race, religion, physical ability, and other symbols, in order to invite individuals from various backgrounds who resonate with Mercari's mission and values.
