Sanjo's summer festival in Niigata closes on the night of August 1, 2026 with its grand fireworks at the Kami-Sukaro river flats. The festival traces back to 1952, when local metalwork traders invited their clients to the 'Sanjo Kanamono Matsuri'. About 4,000 shells are fired over two hours from 19:30 — star-mines, rapid successions of shakudama and Niagara cascades. From the designated viewing ground at Rokuno-machi Riverside Green, the bursts overhead and the light pouring along the river can be seen together. About 60,000 attend (2025 figure); Kitasanjo Station is a ten-minute walk away.
The 22nd Sanjo Summer Festival Grand Fireworks are held on August 1, 2026 at the Kami-Sukaro river flats in Sanjo City, Niigata, with around 4,000 shells between 19:30 and 21:30 as the festival finale. The designated viewing ground, Rokuno-machi Riverside Green, frames both overhead bursts and the Niagara cascade flowing along the river in one field of view. Kitasanjo Station is a ten-minute walk; drivers reach the site in about five minutes from the Sanjo-Tsubame IC on the Hokuriku Expressway, with roughly 1,530 spaces centered on free lots at the racetrack (partly paid) and the Sanjo-Tsubame General Ground. The program moves through star-mines, rapid shakudama volleys and Niagara falls, and food stalls gather around the venue. With 60,000 attendees expected, arrive early for the riverside green.
