Isui

Japanese: 渭水 - いすい

The largest tributary of the Yellow River in China. Also known as the Wei River. It originates from the Birdsnake Mountain in southeastern Gansu Province, flows east into Shaanxi Province, passes north of Xi'an, and merges with the Yellow River near Tong Pass. Its total length is about 787 km. Its main tributaries are the Hulu River, the Jie River, and the Luo River. The Wei River irrigates the Wei River (Guanzhong) Plain and served as a means of transporting rice tax to successive dynasties. In recent years, the Jie River Canal was opened in 1935, and canals and irrigation channels such as the Wei Hui Canal have been completed under the People's Republic of China, and new construction and restoration are actively carried out.

Japanese:

中国，黄河最大の支流。渭河とも。甘粛省南東部，鳥鼠山に発し，東流して陝西省に入り，西安の北を経て潼関付近で黄河と合流，全長約787km。おもな支流に葫蘆河(ころが)，【けい】河(けいが)，洛河(らくが)など。渭水は渭河（関中）平野を潤し，歴代王朝への租米輸送の役を果たした。近年では1935年に【けい】恵渠(けいけいきょ)が開通，中華人民共和国のもとでも渭恵渠などの運河や灌漑(かんがい)用水路が完成し，新設，修復が盛んに行われている。
