Culture and Education

この取り組みを通じて目指すゴール: Goal:

To foster a culture in which eliminating the waste of resources is the norm

To make the education needed to work toward a circular economy widespread



In a past survey conducted by the Mercari Group, 55.5% of respondents felt little or no hesitation toward buying secondhand items, and 53.2% of respondents took better care of their possessions*1 as a result of the spread of marketplace apps like Mercari. These results demonstrate a positive change in attitude and behavior.

We believe that if we can use Mercari to promote such change in even more people, we can achieve the waste-free society we are working towards.

With this in mind, we run various initiatives to spread the awareness and knowledge necessary to achieve a circular economy.

Educating the children who will grow up and inherit this world is an essential part of this mission.

We hope to use the model of Mercari and Merpay to teach children the importance of utilizing the earth’s limited natural resources for a sustainable society and the potential of technology to find the solution.

  • “Mercari Challenge” Educational Program in Collaboration with Houkago NPO Afterschool

    This educational program uses online quizzes and workshops to teach elementary school students about the circular economy and the value of unneeded items. We created this program in collaboration with Houkago NPO Afterschool, which works together with local communities to operate after-school programs in order to help children grow and learn.

  • A Green Friday sustainable fashion show with no new items

    We held a fashion show where stylists created outfits by combining clothes they bought on Mercari with secondhand clothes brought in by users. Through this event, we aimed to show the public the potential and fun of mixing and matching old clothes to make new fashion.

  • Educational Program for Using Marketplace Apps Safely & Securely

    This free-of-charge educational program offered by Mercari teaches young people, guardians, and educators how marketplace apps and other C2C services work, gives case studies illustrating how to avoid trouble when buying and selling, and asks participants to proactively consider how they can use these apps in a safe and secure way. To date, we have held this program at junior high schools, senior high schools, and boards of education in Chiba, Gifu, and Osaka.

  • Mercari Hands-On: Learning the Value of Possessions and Money

    This educational program uses Mercari to teach elementary school students the value of their possessions and money. Using the Mercari app and “Mercari Observation Notebook,” students simulate the Mercari listing process together with their parents, taking time to consider how much their possessions are worth from various perspectives. In this way, they are able to learn the value of money, such as how it can be used to generate profit.

  • Problem-Based Learning (PBL): Perspectives on Value Exchange 20 Years from Now

    This program was created based on the idea of “value exchange engineering,” a concept which mercari R4D is researching alongside The University of Tokyo’s Research Institute for an Inclusive Society through Engineering (RIISE). It aims to inspire interest in environmental and social issues among students, empower them to develop their own solutions, and put those solutions into action. The first session was held as part of “Project N,” the problem-based learning module at Kadokawa Dwango Educational Institute’s N High School. Titled “Project 2040: Perspectives on Value Exchange 20 Years from Now,” the course had students come up with a business or service to support value exchange in the future.
