The oldest material about cormorant fishing in Mino Province is “Ukaibe Medsurame,” a description in the family resister of Kakamigahara Nakazato from 702 (Taiho 2). Based on this data, the origin of the Kiso cormorant is considered to goes back to 1300 years ago. It is said that Naruse Masachika, the third lord of Inuyama Castle, started the tradition about 340 years ago as the Imperial cormorant fishing and protected the fishermen. They used to discontinued the fishing when the moon was full or the river became muddy. After Meiji 42, however, they conduct the fishing everyday except when a typhoon comes or the river rises as it is a tourist attraction now.
