Asaka Sosui is a major project that draws lake water from Lake Inawashiro in the Asaka wilderness of Koriyama, which has been a barren land with poor water use since ancient times. The excavation of Asaka Sosui began in 1897 and became Japan's first agricultural irrigation project under the direct control of the country.
After spending about three years, he invested a total of 850,000 labor force and a total cost of 407,000 yen (about 40 to 50 billion yen when converted to the current monetary value). Asaka Sosui, which extends 52km from the main canal and 78km from the diversion canal, has been completed, and a new paddy field of about 3,000ha has been created.
Asaka Sosui is used as a power supply source (the earliest hydroelectric power plant in Japan, "Numagami Hydroelectric Power Plant") in addition to agriculture, and has developed the silk reeling industry and has led to the subsequent expansion of chemical plants. We laid the foundation for Koriyama, which is called the "economic capital".
安積疏水は、古くから水資源の乏しい不毛の地であった郡山市の安積原野に、猪苗代湖から水を引いた一大プロジェクトです。
安積疏水の開削は1897年に始まり、日本初の国の直轄農業水利事業となりました。
約3年を費やし、延べ85万人の労働力と40万7千円（現在の貨幣価値に換算すると約400～500億円）の費用が投じられ、幹線水路から52km、分水路から78kmに及ぶ安積疏水が完成し、約3,000haの新たな水田が作られました。
安積疏水は、農業以外の電力供給源（日本最古の水力発電所「沼上水力発電所」）として利用され、製糸業を発展させ、その後の化学工場の進出をもたらし「経済県都」と呼ばれる郡山の礎を築きました。
