The 55th Ajimu Basin Festival - Fireworks launched high into the sky liven up the summer festival
The Ajimu Basin Festival in Usa City, Oita, on Saturday, August 22, 2026, closes with about 700 fireworks over 20 minutes from 20:20 at the Ajimu-Ohashi riverbed on the Fukami River. The day's stage features marching, the Himiko dance rooted in the town's history and the bon dance, alongside a grand uchiwa-fan raffle and a bingo game for elementary schoolers — with rows of food stalls. The venue is 5 minutes from Ajimu IC, with free parking for about 200 cars.
Under the wide sky of the basin, the festival stage opens with the ceremony's marching band, then the Himiko dance and the bon dance take over, rooted in the town's name and history. Family-friendly fixtures such as the uchiwa grand raffle and the children's bingo keep the afternoon lively before some 700 fireworks rise from the Fukami riverbed to close the night. The Ajimu-Ohashi riverbed is about 5 minutes' drive from Ajimu IC on the Usa-Beppu Road, or 20 minutes by taxi from JR Yamage Station, with a free 200-space lot. For the day's schedule and any cancellation, check the Ajimu branch of the Usa City Tourism Association or the city's official website. With plenty of stalls, the festival is well suited to an early dinner on site.
