Over 1,000 carp are released into the Seto River canal during the warmer months.
In winter, the koi are moved to a warmer indoor facility to protect them from the harsh Hida mountain climate.
The white-plastered storehouses were historically built with thick fireproof walls to protect valuable silk and rice stocks.
The stone walls of the canal were constructed using local river stones without the use of mortar.
The sound of the flowing water is officially designated as one of the '100 Soundscapes of Japan' by the Ministry of the Environment.
Setogawa and Shirakabe Dozou Street is a historic district in Furukawa, Hida, defined by its white-walled storehouses (dozo) and a crystal-clear stone-lined canal. The canal, originally diverted for irrigation and fire prevention, now serves as a scenic artery populated by hundreds of colorful koi carp. The street features preserved Edo-period architecture, including traditional merchant houses and temples. It gained international recognition as a filming location for the animated film Your Name. The canal water is maintained by local residents to ensure the health of the fish. Walking paths run parallel to the waterway, connecting the town's central historic core. The area remains an active part of the local community rather than a static museum piece.
