Prior to the Spring Kōbō Daishi Memorial Ceremony and Yukumishiki Ritual on April 21,
the "Mandoue" (Ten Thousand Lanterns Ceremony) lights up the night in Shuzenji Onsen.
During the day on the previous day (April 20th), the "O-Nobori" (Sacred Procession) takes place, in which the portable shrine enshrined in the Daishido Hall of Shuzenji Temple is carried to Oku-no-in by bearers dressed in white robes and eboshi hats. Along the way, the powerful chants of "Namu Daishi Henjo Kongo" resound through the streets, while well-wishers along the route throw small offerings.
