Introduction
Our Mission
Mercari’s US business started operations in 2014. With a mission to make selling easier than buying, Mercari US aims to provide a service where people can easily sell almost anything online. The US business still hides tons of untapped growth potential, through shipping innovations such as the expansion of same-day delivery, automation that mitigates users’ price-setting confusion by suggesting prices, and other features. In order to facilitate the US business’s development while generating synergy with Mercari’s Japan business, our US operations are developing their product not only in the US offices, but in Japan (Tokyo) as well. Mercari US is a foundational pillar in building towards Mercari Group’s mission of “create value in a global marketplace where anyone can buy & sell.” Will you join us in taking on this mission?

Our Culture
Mercari’s culture has been central to the company since our founding, with the three core values of Go Bold, All for One, and Be a Pro. In addition, the “Trust & Openness” value was introduced to embody our culture of mutual trust, where information remains transparent and rules are kept to a minimum. Regardless of how big Mercari gets, our culture is essential to achieving our mission and will be promoted throughout our organization.
