This is an event that has continued for more than 300 years. It is held to pray for a bumper catch of fish, abundant crops and safe journeys on the ocean.

On the eve of the festival vigil, a boat with paper lanterns hung overhead crosses Ine Bay and at the annual celebration, a sairei-sen (a ritual boat) and a kagura-sen (a Shinto music and dance performance boat) sail on the Ine bay.

A sword-waving performance is dedicated to the god of the Yasaka shrine. This festival is called "a Gion festival at sea" since visitors can enjoy food stalls on boats.
