Lake Haruna Fireworks Festival

Summary

The Harunako Fireworks Festival spreads over Lake Haruna in Takasaki City, Gunma, on Friday, August 7, 2026, from 20:00 to 21:00 — about 1,500 shells plus underwater fireworks opening across the lake surface. The caldera-rimmed basin bounces sound around the shore, giving the display its distinctive resonance. Road controls start at 17:00; shuttle buses link the free 800-car temporary lot to the lakeside, and paid seats are offered. In bad weather the event moves to Friday, August 14.

Overview

Set inside the ring of mountains, Lake Haruna gives this festival a natural sound shell: bursts echo off the slopes, and underwater fireworks add light close to the surface. The hour-long program from 20:00 mixes standard launches with these lake-specific effects, and the cool mountain evening suits a long stay by the shore. Road controls begin at 17:00 around the lake. Drivers reach the area in about 30 minutes from the Shibukawa-Ikaho IC on the Kan-Etsu Expressway and park in the temporary lot (800 spaces, free), then ride the shuttle bus to the shore. Paid viewing seats are available. Nights at the lake cool quickly in the mountains, so bring a layer. If weather intervenes, the event is scheduled to move to Friday, August 14 — check the day's announcements. No food stalls are planned, so bring your own drinks.
