Regardless of how big Mercari gets, our culture is essential to achieving our mission and will be promoted throughout our organization.

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.
