Comment
“Manpo” refers to an underground water channel for farming. It played an important role in developing new rice fields. During the Ansei period (1854~1859), Sakonshiro, who served as kimoiri (village head), constructed a 700-meter irrigation canal for developing new rice fields. Part of the canal running under Takanoyama is the Funaogawa Manpo which still exists in Kakiyoshi-machi, Nanao City (former Funao-mura, Tatsuruhama Town). Kasuga-yosui runs at the foot of Mt. Hyakujo, almost along the 90-meter contour line. As the gradient is less than 1/200, the flow is gentle. The Manpo in Yukawa-machi, constructed in 1897, is called “Hodatsu” by the locals, because the engineers involved came from Hodatsu Village (current Hodatsushimizu-cho). The former Fukami Village in Nanao City also has a huge 300-meter underground water channel called “Fukami-mura Manpo,” which is said to have made as follows: A boat called “Geta-bune” was struck against the mountain, and then soil was dropped into the boat from both sides. The soil was transported to the reclaimed land. We can surmise that back then there were already civil engineers with advanced technological skills in Noto.
