The Evolution of the Omagari Hanabi National Fireworks Competition and Fireworks in Japan (After the War – the Period of Restoration)

Since the Manchurian incident in 1931, the society appeared distressed as the country was moving toward war against China, leading to the cancelation of the competition. Even though the event was revived once in 1936, there was no choice but to cancel the competition from 1937 to 1945. In 1946, the competition was relaunched during the chaos of post-war society. The quick restoration of the popular event seemed to be an encouraging sign and spread hope among people. Moreover, the restoration of the competition also highlighted the Omagari people’s love for fireworks. From 1949, the name of the competition was finally changed to Omagari Hanabi National Fireworks Competition, which continues to stand even today.
