Hachiemon Deguchi Yusui Spring bubbles forth copiously from the root of a large tree standing beside Izumi Line, a highway that passes through Izumi-cho Town, Hokuto City. As one of the three water sources that were managed by the three communities (districts) of former Nagasaka-cho Town, namely Nagasaka-kamijo, Nagasaka-shimojo, and Shibusawa, it has long supplied water to paddy fields in this region ever since water channels have been installed in the beginning of the Edo Period (1603-1868).
There is a story of how the spring got its name. One day, a man named Hachiemon went to the mountain and happened to save a snake from a mountain fire. In return, the snake gave him a toothpick as a token of his appreciation. When Hachiemon stuck the toothpick in the ground on a hill behind his house, clear water is said to have sprung forth.
