Sponsor banners in a converted grocery-store assembly hall, rural Japan, warm light

Sponsor ZuCity Japan

A community-owned popup city in Komoro, Nagano, 90 minutes from Tokyo — with an audience of builders that returns every year.

Sponsor the Annual Popup City

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.

Ways to Partner

Venue Branding

Your name on the converted grocery-store hall and the basement club for the season.

Themed-Week Sponsorship

Back a single assembly week — d/acc, DeSci and longevity, jp/acc policy, or the recovery week.

Ecosystem Partnerships

Grants, bounties, residencies, and product pilots run with the community between editions.

Speak at ZuCity

Assemblies run on speakers, not panels. Talks on AI, longevity, regen, and network states are curated year-round for the popup weeks.
