Kuji River

Japanese: 久慈川 - くじがわ

A river that flows through northern Ibaraki Prefecture. It originates from Mount Yamizo on the border with Fukushima Prefecture, merges with the Yamizo River and Sato River along the way, and empties into the Pacific Ocean at the border between Hitachi City and Tokai Village. It is 124 km long. River terraces have developed in the midstream north of Hitachi-Omiya City, with the upper terraces used as farmland and the lower terraces used as rice paddies. In Daigo Town upstream, incised meanders and gorges can be seen, and along with its tributary, Fukuroda Falls, it belongs to Okukuji Prefectural Natural Park. The river water is used for drinking water and industrial water for Hitachi City and other areas. The mouth of the river was L-shaped due to coastal flow, but has been remodeled to be straight. Hitachi Port was built on the left bank of the old mouth, where heavy electrical equipment is shipped and northern timber is unloaded. The Japan Atomic Energy Agency has a facility in Tokai Village on the right bank of the mouth.

Kuji River

This river originates at the northern foot of Mt. Hiraniwa (1,060m) in northeastern Iwate Prefecture, flows eastward and empties into Kuji Bay. It is about 40km long. For about 5km from Imodanibashi Bridge to Iwaibashi Bridge in Kuji City, it forms a deep gorge, and both banks are gray-white cliffs made of limestone. It is called the Kuji Stream and is part of the Kuji Hiraniwa Prefectural Natural Park. In the lower reaches, the Naganai River and Natsui River join together, forming an alluvial lowland.

茨城県北部を流れる川。福島県との県境にある八溝山より発し，途中八溝川，里川などと合流して日立市と東海村の境界で太平洋に注ぐ。全長 124km。中流の常陸大宮市以北には河岸段丘が発達し，上位段丘は畑地，下位段丘は水田として利用。上流の大子町では穿入蛇行や峡谷がみられ，支流の袋田の滝とともに奥久慈県立自然公園に属する。河水は日立市などの上水道，工業用水に利用される。河口部は沿岸流のためL字形をなしていたが，直線状に改修された。旧河口左岸に日立港が建設され，重電機器の積み出しや北洋材の陸揚げが行なわれる。河口右岸の東海村に日本原子力研究開発機構の施設がある。
