The Lake Kawaguchi Kojosai caps Fuji Five Lakes summer with about 10,000 fireworks over the water on the fixed date of August 5 — and when the weather cooperates, Mt. Fuji itself looms behind the bursts. Lakeside launch means clean reflections and an amphitheater of mountains that makes every shell echo.
Background
The Kojosai ('lake celebration') dates back over a century as a festival honoring the lake itself, and closes a two-day waterfront matsuri with its fireworks night.
Getting there
The venue is Funatsuhama on the lake's southern shore, 10–15 minutes on foot from Kawaguchiko Station (Fujikyu line; about 2 hours from Shinjuku by direct limited express or highway bus).
Tips
- Fuji visibility is a lottery — August haze hides it more often than not, so treat a clear mountain backdrop as a bonus, not the promise.
- The last trains and buses toward Tokyo leave uncomfortably soon after the finale; either book lakeside lodging months ahead or plan a highway bus with reserved seats.
- The eastern lakeshore near Oike Park is less packed than Funatsuhama itself.
- Evenings at 800m altitude are cool even in August — bring a light jacket.
