The 5th Oshu Fireworks Festival - Enjoy vibrantly colored fireworks in full bloom
The Oshu Fireworks Festival — reworked in 2022 from the long-loved Mizusawa display and now hosted in turn by districts across Oshu City, Iwate — lands in the Isawa district on Saturday, August 22, 2026. The viewing field is the parking area near the Oshu Isawa Canoe Course on the east side of Isawa Dam, with 9,000 shells over roughly 70 minutes from 19:10. The 2025 edition drew about 9,000 spectators. Paid seats are available; free parking holds 1,000 cars.
The district-rotation format means each year's venue differs — in 2026, the special site east of Isawa Dam opens its sky to the show. The program spans 19:10 to 20:20, long enough for star-mine phases and single-shot highlights to alternate with room to breathe, carrying forward the scale of the old Oshu Mizusawa display. There is no rail stop nearby: take a taxi about 35 minutes from JR Mizusawa Station or 45 minutes from Mizusawa-Esashi Station on the Tohoku Shinkansen. Drivers come about 33 minutes from the Mizusawa IC on the Tohoku Expressway. The free lot holds 1,000 cars, but a display this size packs it early — arrive with time to spare. Paid viewing seats are offered; see the official website for purchase details. No food stalls are planned, so bring your own drinks.
