Choyo-no-Shinji and Crow Sumo Wrestling is Shinto rituals performed on September 9 at Kamigamo Shrine, which is famous as the oldest shrine in Kyoto. According to the concept of Yin and Yan, the odd number is the number of Yan (shine). Thus 9 is considered to be the number that Yan reaches to an extreme. As September 9 is the day when the extreme Yan overlaps, it was called Choyo (Double Yan) and was celebrated as the auspicious day since the ancient times. Since September is the blooming season of a chrysanthemum by the lunar calendar, it is also called the Chrysanthemum Festival.

In the old days, people drank chrysanthemum wine and purified themselves with dew on chrysanthemum petals in hope of a long life. Today, people in Kyoto visit Kamigamo Shrine on this day and offer chrysanthemum flowers to the deity and pray for the healthy life.

After the Choyo Shinto rituals are performed‚ a Shinto priest called “Tone” places a bow and arrow and a sword against a cone-shaped hill of sand. He then utters the cry “kaa‚ kaa‚ kaa‚ koo‚ koo‚ koo,” imitating the cawing of crows. After this ritual‚ children, divided into two teams of “Negi-kata (priests)” and “Hori-kata (people who cerebrate),” wrestle each other in matches. The sumo wrestling originates in an ancient Shinto rituals performed in the Heian period (794-1192) and it is designated as an intangible cultural property of Kyoto City. Free chrysanthemum flower sake will be offered that is believed to be effective for healthy longevity.
