Venue and Map
The Oshu Fireworks Festival will be held at the “Isawa Dam East Side Special Venue” in Wakayanagi, Isawa, Oshu. More specifically, the parking area near the Oshu Isawa Canoe Course will serve as the viewing venue. Since the fireworks are launched from the top of Isawa Dam, visitors can enjoy an impressive spectacle rarely seen elsewhere, along with the magical sight of fireworks reflected in the dam’s lake.
Access
Traffic restrictions will be in place around the venue on the day of the fireworks festival, and some sections will be closed to vehicles, so please plan accordingly.
By Train
- JR Tohoku Main Line “Mizusawa Station”: Approximately 35 minutes by car.
- JR Tohoku Shinkansen “Mizusawa-Esashi Station”: Approximately 45 minutes by car.
Paid shuttle buses are also scheduled to run from Mizusawa Station to the venue, so using public transportation is recommended. Be sure to check the time of the last train home in advance and allow plenty of time for your return journey.
By Car
- Tohoku Expressway “Mizusawa IC”: Approximately 33 minutes by car.
- From Mizusawa IC, take National Route 4 and Prefectural Route 236, then continue approximately 23km along National Route 397 toward Oshu Lake.
Approximately 1,000 paid parking spaces are expected to be available around the venue, but spaces are limited and heavy congestion is expected. Consider arriving early or taking the shuttle bus.
Reserved Seating and Tickets
As of July 2026, no official announcement regarding reserved seating for 2026 has been confirmed. Please wait for further official information.
For reference, the following reserved seats were available in 2025:
- Table seating (4 people): 11,000 yen per set (one table, 4 chairs, and one designated parking pass included)
- Chair seating (2 people): 5,500 yen per set (2 chairs and one designated parking pass included)
These reserved seats generally go on sale around late May each year and tend to sell out quickly. Admission to the general viewing area is free.
Lesser-Known Viewing Spots
Because the Oshu Fireworks Festival launches fireworks from a dam, relatively clear views can be expected from open areas around the venue.
- Isawa River riverbank The riverbank along the Isawa River, which flows immediately beside the east side of Isawa Dam and the venue, is a familiar viewing spot for local residents. By avoiding the crowds at the main venue, you may be able to enjoy the fireworks in a more relaxed setting. However, because it is close to the launch site, arriving early to secure a spot is essential.
- Slightly distant elevated areas around Isawa Dam Since the fireworks are launched from the top of the dam, elevated areas around the dam or hills a short distance from the venue offer views across the entire display. If you particularly want to see the fireworks reflected upside down in the dam’s lake, viewing from a little farther away is recommended. However, never enter private property or restricted areas.
- Around the Oshu Isawa Canoe Course Since the festival venue is the parking area near the Oshu Isawa Canoe Course, the open areas around the course may also be suitable for viewing. However, as this area is adjacent to the main venue, crowds are expected here as well. Arrive early and secure a spot with a clear view.
These lesser-known viewing spots are not officially designated viewing areas, so they may not have facilities such as restrooms or food stalls. Bring a picnic sheet, drinks, insect repellent, and other necessities, and enjoy the fireworks while being considerate of others.
