A community-owned popup city in Komoro, Nagano, 90 minutes from Tokyo — with an audience of builders that returns every year.
The popup city runs every autumn — Sept 4 – Oct 5, 2026 for the current edition — four themed assembly weeks in our own venue and houses. Sponsorship compounds: the venues, equipment, and relationships stay in the neighborhood year over year.

Back a single assembly week — d/acc, DeSci and longevity, jp/acc policy, or the recovery week.
Grants, bounties, residencies, and product pilots run with the community between editions.
Assemblies run on speakers, not panels. Talks on AI, longevity, regen, and network states are curated year-round for the popup weeks.
