The festival started in 1733 as part of a ceremony to pray for the spirits of the victims of the great famine in 1732 and to drive away the evil disease.
This festival is broadcast live every year. I saw it on TV again this year. The river is surrounded by the overcrowded area, so the size of shells are restricted.

The first Japanese to get a patent in the United States was Jinta Hirayama(平山甚太), a pyrotechnician from Yokohama. His "Daylight Fireworks（昼花火, Hiru-hanabi)" was patented. he fireworks release colored smoke instead of sparks while emitting a sound.
Wari-mono(chrysanthemum type) are the typical Japanese fireworks which burst across the sky in a circle. They change colors while spreading in cirle and draw muti-layered concentric circles in the sky.
