This is an event held since 1956 to announce the coming of spring at Lake Biwa.
In the event, prayers for safety on the lake are offered; the blessing of water is appreciated; and the environmental protection of the lake is appealed for.
At the water parade on the lake, the mayor and the honorary captain on the Michigan cruiser throw a golden key which implies the meaning of “opening the door of spring” into the lake. Every year, a main actor of NHK morning drama serials is chosen as the honorary captain. On the deck, a Shinto priest offers prayers for safety on the lake.
