Iiyama Decarbonization Fair 2026

Family-Friendly

A fun, hands-on day of green living and disaster readiness

The Iiyama Decarbonization Fair 2026 (いいやま脱炭素フェア2026) fills the Iiyama Cultural Exchange Center Natura with ideas for energy-saving homes, renewable energy and disaster preparedness. Admission is free.

Try your hand at a crane game using battery-powered construction machines, make a keychain powered by an electric car, or build with wooden blocks and join a parent-and-child woodworking class. In a snowy town like Iiyama, a warm home and good preparation matter. Come along with the family and pick up some ideas for everyday life.

The autumn festival “IIYAMA Nikkori Marché” is held at the same time nearby, so make a day of it.
