Asahi Yamabiko Fireworks Festival: The sight of fireworks launched over the mountain village is spectacular
The Asahi Yamabiko Fireworks run for 25 minutes from 20:15 on Saturday, August 15, 2026, on the Yahagi riverbed in the Asahi district of Toyota City, Aichi. About 1,000 shells rise at low altitude in the mountain-basin setting, so the sound and light land close at hand. Earlier, from 17:30, the traditional Koten Tenno festival fills the district with drums and a torch procession. Rain or shine — though severe weather cancels — with free temporary parking for about 300 cars a 3-minute walk from the river.
On the Yahagi riverbed deep in the hills of northeastern Toyota City, the fireworks climb from low launch positions and spread overhead, close enough that the report rolls straight across the water. Beforehand, from 17:30, the Koten Tenno festival rite sends drum processions and bearers of two-meter torches running through the district — a rite of passage into the summer night before some 1,000 shells take over the sky. Access is by car, about 30 minutes northeast from Edge Shita IC on the Sanage Green Road, with a free temporary lot of about 300 spaces a 3-minute walk from the riverbed. The event is held in rain but cancelled in severe weather, so check the Asahi Tourism Association's notices if the sky looks doubtful. Food stalls gather around the venue for festival-style grazing.
