The summer festival season at the Five Fuji Lakes kicks off with a festival at Lake Yamanaka, and the festival season comes to an end with the biggest of the festivals, the Lake Kawaguchi Kojosai. The festival takes place every year on August 4th and August 5th. On the 4th, the eve of the main festival, a dance stage and a small fireworks display using skyrockets are held, while on the next day a live concert by the lakeside is followed by the grand fireworks show. What with jumbo star mines, barrages of large ball fireworks, musical star mines, and more, between the two evenings a total of roughly 10,000 fireworks light up the summertime night sky.
