The Mercari app was built upon the mission to “create value in a global marketplace where anyone can buy and sell.” In just over 5 years since its release in July of 2013, the app has grown to become a service known and used by many, boasting over 70 million downloads cumulatively in Japan and over 10 million users on a monthly basis. Through familiarizing people with the idea of a marketplace where individuals can use their smartphones to easily buy and sell items, we have been able to realize a world in which items that people no longer need are passed on to people who do need them, and have accumulated over 1 billion in-app listings to date.
