This is Kayanowa Kuguri, which is a festival for health during summer time. In this festival, people pass through Kayanowa, which is a ring made from leaves of Kaya (Japanese Nutmeg Tree). This is a ceremony to drive off bad luck and pest during hot weather by passing through the holy ring. In this shrine, this ceremony starts from 1 A.M on August 1st. It is believed that the leaves of Kaya, resembling swords in shape, have a power to cut down bad things. So, pest and bad luck are cut off from people having passed through the ring made from Kaya leaves.
