Saiko Ryugu Festival Fireworks

Summary

The Saiko Ryugu Festival Fireworks are held on Lake Sai in Fujikawaguchiko Town, Yamanashi, on Sunday, August 2, 2026 — a festival tied to Senoumi Shrine, which enshrines the water deity Toyotama-hime. From 19:30, 1,000 shells rise for 20 minutes off the lake's Maehama shore, with star mines mirrored on the surface, before a crowd of about 5,000. The venue is about 15 minutes by car from the Kawaguchiko IC on the Chuo Expressway, with 200 free parking spaces nearby — and note that no buses run once the display ends, so plan around driving or staying over.

Overview

Senoumi Shrine stands on the shore of Lake Sai, enshrining the water deity Toyotama-hime, and the Saiko Ryugu Festival is the summer celebration tied to it. The fireworks run 20 minutes from 19:30, with 1,000 shells rising off the Maehama shore and star mines among them reflecting on the lake. With Mt. Fuji's foothills surrounding the water, the sight spreading across both sky and lake is what makes this display special. The Maehama venue is about 15 minutes by car from the Kawaguchiko IC on the Chuo Expressway, with 200 free parking spaces nearby. One caution: no buses operate after the display finishes. A day trip assumes coming by car; alternatively, stay at a nearby campground or hotel and fold the next day's Lake Sai or Lake Motosu sightseeing into the plan. With about 5,000 attending, claim a good lakeside position early.
