Higashikawa

Japanese: 東川 - とうせん
Higashikawa

A district under the jurisdiction of Kunming City in the northeastern part of Yunnan Province, China. It is located in the Xiaojiang basin, a tributary of the Jinsha River. The permanent population is 271,917 (2010). For the past 2,000 years, it has been known as a source of high-quality copper called "Yunto". In 1954, the Dongchuan mining area was separated from Huize County to develop China's largest copper mine, centered on Tangdanshan in the northwest. It was incorporated as a city in 1958, and became a district of Kunming City in 1998. The copper content of the ore from this mine is said to be 25-50%. A branch line runs through it from Sitangzi on the Guiyang-Kunming Line (Guiyang-Kunming).

中国、雲南(うんなん)省北東部の昆明(こんめい)市の市轄区。金沙江(きんさこう)支流の小江流域に位置する。常住人口27万1917(2010)。2000年前から「雲銅」と称する良質の銅の産地として知られた。1954年北西部の湯丹山(とうたんざん)を中心とする中国最大級の銅山を開発するため、会沢(かいたく)県から東川鉱区が分離され、1958年に市制を施行したが、1998年に昆明市の一区となった。同鉱山の鉱石の銅含有率は25~50%といわれる。貴昆線(貴陽(きよう)―昆明)の四塘子(しとうし)から支線が通じる。
