Flow of the course

About this spot

Held on Saturday, August 15, 2026, this fireworks festival represents summer in Shinshu Saku (信州佐久). About 4,000 fireworks are launched from the Chikuma River riverbed (between Saku Bridge (佐久橋) and Nozawa Bridge (野沢橋)), with powerful starmine shells filling the night sky, making full use of the wide river. The way sound resonates across the basin surrounded by mountains is another highlight. It is a thoroughly powerful finale, fitting for the end of a day spent fully exploring Saku's history and nature.

Tips

In case of severe weather, the event may be canceled or postponed, so check Saku City's official announcement on the day for whether it will be held. The surrounding roads and Sakudaira Station (佐久平駅) get very congested after the event ends, so leaving with a time gap is recommended. It can get chilly at night, so do not forget something to wear over your shoulders.

Best time to visit

Time your visit for the 7:30-9:00 PM event. Secure your viewing spot 1 hour before it begins.
