One of the world's largest single-blast fireworks was launched over Nagaoka, Japan, lighting up the night sky in a breathtaking display. Known as the Yonshakudama (ๅๅฐบ็), this massive shell reaches a diameter of up to 1.2 meters (4 feet) and explodes into a dazzling sphere over 800 meters wide. The firework is part of the famous Nagaoka Fireworks Festival, celebrated for its scale, tradition, and emotional impact.
