About the Event & Organizer

Kesennuma Hackathon 2025 is a global hackathon and residency happening in Kesennuma City, Miyagi, Japan.

Dates: October 5–17, 2025

Main Hackathon: October 10–12, 2025

Kesennuma Hackathon is a civic tech hackathon and two-week residency to be held from October 5-17, 2025, in Kesennuma City, Miyagi Prefecture, Japan. With a focus on AI and Web3, this global event invites specialists—developers, engineers, designers, and researchers—from both Japan and overseas to collaborate directly with the local community. After a few days of ideation and collaboration (Oct 6-9) to identify regional challenges, particularly issues like declining birth rates, an aging population, and economic stagnation, teams will sprint to build technological prototypes during the hackathon proper (Oct 10-12), followed by a public demonstration and showcase on October 13. The final days (Oct 14-17) are dedicated to refining and improving solutions based on feedback, with an eye toward real implementation.

The event is led by the Kesennuma Hackatsuon Executive Committee, with Hikari Igarashi as Committee Lead and Luciano DeAngelo as Co-Lead. Local partners include Kesennuma City Government, Kesennuma Town University (Machi Daigaku), and other community groups. Numbers for total guests, speakers, and media will be shared closer to the date.
