Kameyama Lake Festival Kimitsu Citizens Fireworks Festival - Star mines reflected across the lake invite you into a fantastical world
Deep in the Boso hills, this lakeside show uses a dam reservoir as its mirror: echoes bounce between forested slopes while about 3,000 shells—led by big 1-shaku and 8-sun rounds—reflect off the water in a 30-minute program from 19:30 on October 3, 2026. The venue is 7 minutes on foot from Kazusa-Kameyama Station on the charmingly rural Kururi line, and free shuttle buses bridge the distance from free parking for those driving.
Kameyama is a reservoir formed by damming the Obitsu River, and on October 3 the lakeside park becomes the viewing zone for a 19:30–20:00 program. By rail, ride the Kururi line from Kisarazu to its terminus Kazusa-Kameyama, then walk 7 minutes—part of the charm is arriving on one of Japan's least-known local railways. Drivers coming via the Kimitsu IC and Boso Skyline need about 30 minutes, with roughly 700 spaces (some paid) linked to the site by free shuttle. The signature experience is acoustic: heavy shaku-goku shells open with a thump that rolls around the hills in ways flat-city shows never manage. Rough weather cancels with no reserve date; recent crowds run to about 40,000. A handful of vendors set up near the dam, and the station walk crosses quiet forest roads that are only faintly lit after dark—a small flashlight earns its place in your bag.
