Tokoro River

The Tokoro River is a river in Hokkaido, Japan.
The Tokoro River, which has its source in Mount Mikuni, flows through Oketo and Kunneppu and into the Sea of Okhotsk from Kitami. Many white-tailed eagles and Steller's sea eagles that have been designated as protected species by the national government are observed in its basin. A colony of purple azalea designated as a natural monument by the Hokkaido government and a forest of large-diameter Japanese elm trees along the Muka River, which flows parallel to the Tokoro River, are symbols of the region. At the Tokoro River Estuary Site, relics, remains of pit-dwellings and tomb pits from the Jōmon period have been found.
