The Nibutani Dam was constructed in Nibutani (二風谷) district on the Saru River, though there was a strong objection due to a sacred meaning of the place for indigenous Ainu people. Nibutani is the site of the Ainu Cultural center. Nibutani's best known son is perhaps Shigeru Kayano, an advocate for the Ainu and Ainu language and culture. The 'Cultural Landscape along the Saru River resulting from Ainu Tradition and Modern Settlement' within Biratori has been designated an Important Cultural Landscape.
