2026 Koshigaya Fireworks Festival: Full-Day Enjoyment Course

With the Koshigaya Fireworks Festival, held on Saturday, July 25, 2026, as the highlight, this full-day course lets you enjoy summer in Koshigaya, Saitama Prefecture, from midday onward. In the afternoon, walk the lush approach path of Hisaizu Shrine, Koshigaya's guardian shrine, to set the mood, then cool off by the water at Koshigaya Laketown's large park. In the evening, move to the Kasai Yosui riverbank to secure a spot and enjoy the food stalls around Chuo Civic Hall while waiting for the show to start. It's a quintessentially Koshigaya day plan, gazing up at the summer night sky together as a family in a riverside town that retains its old-town charm.
