Takase Dam, located in Omachi City, Nagano Prefecture, is a massive rock-fill dam with a height of 176m and a volume of 11.59 million m³. It holds the distinction of being the second tallest dam in Japan and was selected as one of the '100 Best Dam Lakes' in 2005. The dam is constructed using rock and gravel excavated from the lakebed. Surrounded by a National Park, the area offers a rich, ever-changing natural environment that showcases the harmony between human engineering and the wilderness.
History & Cultural Background
Construction began in 1971, and the dam was completed in 1979. The dam lake is named after a local legend involving 'Sairyu and Ko-taro Izumi,' and a bronze statue of a dragon and a boy can be found along the shore. Furthermore, the area is geologically significant due to the presence of 'Funtoka,' a National Natural Monument formed by the accumulation of minerals from hot spring water.
