PIAZZA Inc. (CEO: Kohei Yano, hereinafter 'PIAZZA'), operator of the local community app 'PIAZA,' has signed a collaboration agreement with Koganei City, Tokyo (Mayor: Tohru Shirai), aimed at fostering connections among residents.

Through this partnership, PIAZZA will promote information sharing and community engagement within Koganei City, working toward building a local platform where people of all generations can connect.

This marks the 16th municipal adoption in Tokyo and the 80th across Japan.

- Background of the Collaboration

Koganei City is advancing redevelopment and urban renewal projects, particularly around Musashi-Koganei Station. There is a growing need to utilize newly developed spaces to create sustainable mechanisms that attract and circulate foot traffic. At the same time, local shopping districts and community groups are facing challenges such as aging membership and a shortage of successors, making it essential to encourage participation from younger generations, families with children, and new residents.

PIAZZA is a local platform designed to foster loose connections among residents, enabling anyone to freely share and exchange local information at no cost. By accumulating local information on the platform, PIAZZA ensures that anyone can access community activities at any time. Additionally, PIAZZA supports information dissemination and participation in local activities, helping to convert interest into active involvement. This shared vision has led to the collaboration with Koganei City.

With the mission of 'creating cities where people support one another,' PIAZZA has partnered with 79 local governments across Japan and operates the 'PIAZZA' community app in over 110 areas. The company continues to contribute to sustainable urban development by combining digital and real-world initiatives to revitalize local communities.

Currently, our city is advancing urban development initiatives centered on the redevelopment of the north exit of Musashi-Koganei Station, aiming to create a vibrant and attractive city.

Through this agreement, we expect that using the local community app 'PIAZZA' will create new opportunities for encounters and interactions among residents.
