Sumidagawa Fireworks Festival

The Sumidagawa Fireworks Festival is an annual fireworks festival held on the last Saturday in July, over the Sumidagawa near Asakusa. Unlike fireworks displays in other parts of the world, the Sumidagawa Hanabi Taikai is a competition held between rival pyrotechnic groups. Each group tries to out-do the last, and the result is an incredible variety of fireworks, not just in different colors and patterns, but forming shapes as complicated as Doraemon, Pikachu, or kanji.

Crepuscular rays

Crepuscular rays are rays of sunlight that appear to radiate from the point in the sky where the sun is located. These rays, which stream through gaps in clouds or between other objects, are columns of sunlit air separated by darker cloud-shadowed regions. Despite seeming to converge at a point, the rays are in fact near-parallel shafts of sunlight. Their apparent convergence is a perspective effect, similar, for example, to the way that parallel railway lines seem to converge at a point in the distance.
