Senko-hanabi is a thing that reminds us of summer since the Edo period in Japan 

Ryota Tsutsui (46) has preserved the tradition of orange sparks for 25 years as a Senko-hanabi craftsman However, the tradition is fading away while the domestic fireworks market shrinks and Chinese fireworks are emerging. Only two companies have survived in Japan now. The tradition of Japanese Senko-hanabi has been passed down generations for over 400 years 

This is a tale of people who devote their life to preserve these beautiful and fleeting sparks.
