Moominvalley Lake Fireworks Festival ~Summer 2026: Lake fireworks from Moominvalley Park color the night sky
The confirmed fireworks launch dates for this festival are listed below.
Moominvalley Park in Hanno, Saitama stages its lake-top fireworks on multiple summer dates, starting July 20. As the park's original songs play, bursts rise in unison from the water and light up the night lake. The show runs about five minutes from 19:30 — short but dense — with a special version on 'Moomin Day', August 9. METSÅ is 13 minutes by bus from Hanno Station, and the park has its own parking.
The display is a five-minute burst of choreography over the lake, synced to the park's original songs, with every flash doubling on the water. It recurs across several dates from July 20 into August, and August 9 — Moomin Day — gets the special version. Reach the park by bus from Seibu Hanno Station (about 13 minutes to the METSÅ stop), or by car via the Sayama-Hidaka IC (about 12 minutes), using the 1,100-car paid lot. Because the show is so short, be standing at the lakeside a good 30–45 minutes before the first launch.
