Okuno Dam, Rock-fill dam in Ito, Japan.
The Okuno Dam extends 323 meters across the Ito-Okawa River, creating Lake Matsukawa with a capacity of 4,600,000 cubic meters of water.
Construction of the Okuno Dam began in 1972 and reached completion in 1989, following multiple adjustments to address specific geographical requirements.
The dam forms part of the infrastructure network that supports Ito city, a location recognized for its natural hot springs and coastal position.
