Okadoyumi is a Shinto ritual in which a bow is shot at Outaishi Shrine in Muromoto-cho, Kanonji City on January 7 every year to predict a good harvest for the year.
According to legend, it began when the Koji-no-kami drifted ashore at Muromoto Beach and was enshrined there.
In Okadoyumi, the descendants of those who carried the Koji-no-kami on the right side and those who carried it on the left side still perform the ritual, dividing into left and right ditches. On the day of the festival, the koijyu (a group of believers who form a ko and participate in the festival) sit down with lanterns bearing their family crests, chant the tayu, and shoot arrows at the target. The ceremony was designated as a city-designated intangible folk cultural asset on March 20, 2003. The preservation group is the Okadoyumi-no-Nukabisan Preservation Society.
