Numazu Summer Festival held around the last weekend of July every year is the biggest summer festival in Numazu City, Shizuoka Prefecture. A lot of attractive events including the grand parade of Numazu Shiki-saisai Dance, the competitive performances of Shagiri music, the Japanese drum performance and the Mikoshi parade are held during the day.

Each day ends with a gorgeous fireworks display held over the Kano River. Kano River Fireworks Display, which started during the post-war restoration period, is now the biggest fireworks display held in an urban area in the Tokai district. The riverside is bustled with spectators to enjoy this charming sight of the summer. 9,000 fireworks in total are shot up into the night sky during the two-day festival period. The finale of the festival is decorated with the 470 meter long Niagara Falls.
