Nagaoka Fireworks festival in Niigata is one of the country’s largest, most visited fireworks celebrations. Over 20,000 explosions paint the  sky across the two-day event, which draws visitors from far and wide.

The festival started in its current iteration in 1947, to commemorate victims of some intense bombing during World War II. It’s continued in some form ever since, growing year on year to its current impressive state.
