Tone River Grand Fireworks Festival Fireworks are a traditional culture that Representatives Japan. It was the first time I went to this Tone River Grand Fireworks Festival, and the night sky was lit up by 30,000 flowers, one of the largest in Japan. Ibaraki Prefecture's proud fireworks masters, Yamazaki Smoke and Fire Factory, No Village fireworks Industry, Beniya Aoki Smoke and Fire Shop, and Margaux, the four major fireworks masters one of the best in Japan, performed gorgeously, and I am grateful and grateful that this scenery seen with Kan inn Castle was born in Japan.
