A secure system for buying and selling
Mercari provides its users with an environment where they can trade safely and securely. Mercari also uses an escrow payment system in order to guarantee a safe and reliable transaction service for everyone. In addition, buyers and sellers rate each other, so users can have peace of mind by checking the other party’s past reviews before deciding to engage in a transaction. Furthermore, we have a dedicated customer service system that responds to customer inquiries and monitors the service.
Detecting Violations with AI
Mercari employs AI technology to automatically detect transactions that violate the terms of use. By combining this technology with extensive transaction data and item information data, the company aims to improve the accuracy of the detection systems and use them for a wider range of applications to provide an even safer and more secure environment for all users.
* Examples of items that violate terms of use: gaming accounts, counterfeits, medicine, etc.
Cooperating with Authorities
Mercari strives to provide a safe and secure service for all users by cooperating with public institutions and law enforcement. The aim is to work towards making not just Mercari, but the industry as a whole safer and more secure by participating in organizations such as the Council for Intellectual Property Protection (CIPP), EC Business Association, the Association of Consumer Affairs Professionals (ACAP), and the National Shoplifting Prevention Organization (NSPO). The company also takes a proactive role in exchanging opinions and drawing up guidelines.
Inhibiting fraud by enhancing identity verification
Since February 2019, listers have been required to provide their personal information (address/full name/date of birth) when registering. A user’s sales balance cannot be withdrawn if the name registered does not match the name of the account for the balance transfer; this prevents fraudulent listings, such as stolen goods.
Ample compensation
If a product arrives damaged or defective, we offer returns and compensation. Eligible items include unintentionally purchased counterfeit goods, items with a defect or damage not included in the description, and shipping fees for when an accident occurred with Mercari Shipping. Mercari has strategies to ensure normal items are safely delivered to the buyer, but in the event that a user purchases counterfeit or defective goods, they are also eligible for a return or compensation.
Awareness activities for adolescents and educators
We hold educational activities across the country for middle school and high school students, as well as parents and teaching staff, where we teach them how to avoid trouble on marketplace apps, to ensure they can use Mercari with a sense of security.
In 2012, I slung a backpack over my shoulder and set off to travel around the world. The most life-changing moments I experienced were in areas like South America and the Middle East—countries known as emerging nations. I saw before my eyes how people were trying to live more prosperously, as well as the reality of how limited resources were, and it opened my eyes to the issue that maybe not everyone in the world is able to live their lives in the same way.
When I returned home, smartphones had taken over Japan. I thought, “If we can use this technology to connect individuals all over the world and allow items to be easily bought and sold, maybe we can utilize the world’s resources more effectively and enrich the lives of people everywhere.” That thought was the basis for creating Mercari.
Since Mercari was established, we have grown our services while investing in both people and technology. But in order to become a service used throughout the world, we must genuinely take on our role as a public institution of society and work toward creating a circular economy, improving governance, and more.
What can Mercari do to help solve the issues faced by people around the world. With this question in mind, we will continue striving in our efforts to circulate the world’s resources and help society thrive.
