(Japanese follows English)

▼ Our mission

We are always looking for new challenges to help us fulfill our mission to create value in a global marketplace where anyone can buy & sell.

The world is full of objects and services being produced and sold, but many of them are thrown away without people realizing that they might be valuable to someone else, wasting valuable natural resources. To contribute towards eliminating waste, we have launched Mercari, a marketplace where people can buy and sell easily and safely, in Japan and the United States.

▼ Our three values (Go Bold, All for One, Be a Pro)

We work together to create a global marketplace, but the road to this goal is by no means easy. In order for us to make new innovations and take on new challenges that no one has taken before, all of us take ownership of our work and make use of our knowledge so that we can create the best product possible as one team. To achieve this, we all take action based on our three company values (Go Bold, All for One, and Be a Pro).

▼ The goal of the engineering organization

At Mercari, engineering teams always strive to continuously produce significant results. To do this, our organization constantly welcomes changes and new challenges, cooperates and co-creates, is diverse, offers freedom, and encourages all of us to take ownership and make our own decisions. We want to continue taking on new challenges, working together as one team, going bold, and taking ownership so that we can grow individually, while working toward the realization of Mercari’s mission.
