A new world record has been set for the heaviest firework, which was set off in the city of Konosu in Saitama Prefecture, Japan.

The firework, weighing a total of 460 kg, was set off as part of a festival in the city.

The rocket fired into the air and exploded into a ball of light estimated to measure 800 meters in diameter, while illuminating the sky.

The rocket was certified by Guinness World Records, and the feat joins a number of world records involving fireworks.

On 31 December in 2013, the world record for the largest firework display was set by the Dubai government, after a display consisting of 479,651 fireworks was set off at the Palm Jumeirah Island and the World Islands.
