Hackatsuon (a blend of hackathon and katsuo, the bonito that Kesennuma is known for) is a residency and hackathon co-hosted with Kesennuma City, welcoming builders from Japan and abroad.

Kesennuma is a fishing town in the Tohoku region of northeastern Japan, with over $100M in annual catch. Rebuilt after the 2011 earthquake and tsunami, it now faces the same challenges as much of rural Japan — an aging population, depopulation, and a fragile local economy. Cutting-edge technology tends to reach large cities and corporations, but rarely the local governments and communities working on these social challenges. Hackatsuon exists to change that: not a one-off race for prizes, but an invitation to step into a real place, get to know its community, and co-create with the people who live there.

The 2026 residency runs from September 28 to October 11, in Kesennuma.

Three ways to join:

1. Two-week residency — Sep 28 – Oct 11, 2026

Live in Kesennuma for the full two weeks. After check-in and orientation (Sep 28), residents dive into community input and fieldwork with city staff (Sep 30 – Oct 1), then form teams and build (from Oct 2), sharing progress at a midpoint review (Oct 4) before final presentations. This is the deepest way to experience Hackatsuon — getting to know the town and its people, and building projects rooted in real local challenges alongside developers from Japan and around the world.

1. Weekend participation (hackathon) — from Oct 2, 2026

Can't stay for the full two weeks? Join for the hackathon itself, which kicks off on Oct 2 with team formation and development, and continues through the midpoint review on Oct 4. A shorter but hands-on way to team up, build, and be part of the core creative sprint.

1. Public showcase (Demo Day & reception) — Oct 10, 2026 @ Pier 7

Open to everyone. Come see what the builders have created at the final presentations, and join the reception to celebrate with the community at Pier 7. No coding required — just curiosity and a willingness to connect.

Whichever way you join, Hackatsuon is where a community rooted in place meets a network that spans the world.
