| The Zenibako River (銭函川) runs from Otaru, Hokkaidō, Hokkaidō, Japan and ends in the Sea of Japan. It is a Normal Class River of the Zenibako River System under Japanese River Law. The Zenibako River originates north of Mount Okuteine, near the border with Sapporo City. It runs through mountain woods and meets the Zenibako-tōge River (銭函峠川) as it emerges from the Zenibako Mountain Pass (銭函峠, Zenibako Tōge). Katsuraoka-machi (桂岡町, Katsuraoka Town) is situated around the left bank of its middle course. The river turns eastward where it passes under the Sasson Expressway and National Route 5. It runs through the urban area of Zenibako, turns north, then enters the Ishikari Bay 200 meters southwest of Zenibako Station. The course lower than Route 5 was consolidated with concrete after the 1962 flood. |
