Summary

Every evening from July 24 to August 23, 2026, a ten-minute fireworks show rises over Lake Suwa at Kami-Suwa Onsen, Nagano Prefecture, starting at 20:30. The summer tradition organized by the Kami-Suwa hot-spring inn association launches about 500 shells across the month, with star mines synced to music as its hallmark. Fireworks reflected on the quiet lake surface and sound rolling back from the surrounding hills are part of the pleasure, and staying at an onsen ryokan lets you watch from your own room. There is no dedicated parking; the venue is a ten-minute walk from JR Kami-Suwa Station.

Overview

Suwako Summer Night Fireworks strings together a whole month of short shows above Lake Suwa: 31 nights from July 24 to August 23, 2026, each firing about 500 shells between 20:30 and 20:40. Because each evening lasts only around ten minutes, it slots easily around dinner and a soak in the onsen — the kind of fireworks you can build a whole stay around. Star mines move in time with music, the lake's still water doubles the light, and the sound rebounds off the mountains in a way indoor shows never manage. Many guests watch from their ryokan rooms along the shore, an angle especially popular with couples. There are no food stalls announced, so plan dinner in the onsen town; with no dedicated parking, most visitors come on foot from JR Kami-Suwa Station, ten minutes away. Check the organizer — the Kami-Suwa Onsen Ryokan Association — for the latest schedule.
