Fukara Aqueduct

Fukara Aqueduct (Japanese: 深良用水, Hepburn: Fukara yōsui) is an aqueduct that draws water from Lake Ashi, in Hakone, Kanagawa, westward to Susono, Shizuoka.

[1] Since its completion in 1670, Lake Ashi is emptied by this aqueduct, not by the Haya River.

The water rights of Lake Ashi belong to Shizuoka Prefecture, not Kanagawa Prefecture where the lake is located.

Fukara Aqueduct was constructed in 1666-1670 as a tunnel through Mount Hakone's outer rim to provide irrigation to Fukara Village (深良村, 35°12′40″N 138°56′44″E / 35.2110°N 138.9455°E / 35.2110; 138.9455).

In March 2020, the "Thanksgiving Festival of Fukara Aqueduct's 350th Anniversary" (ja:深良用水350感謝祭) was held in Susono City.
