The Gosekku (五節句), also known as sekku (節句), are the five annual ceremonies that were traditionally held at the Japanese imperial court.
The origins were Japanese practices merged with Chinese practices and celebrated in Japan since the Nara period in the 8th century CE.
The Japanese culture and tradition incorporated this in a unique way that spread throughout the country.
The festivals were held until the beginning of the Meiji era.
[1][2] The artist Ikeda Koson (1801-1866) painted five hanging scrolls in around 1830, which depict the festivals.
