It is said that there are more than 200 facilities in Japan, such as Toukichi, a Pelophylax porosus who has made irrigation canals from a large river and used them to grow rice, and Ganji, a Japanese pond turtle. / Living around me, Itachi no Oryo, and crab shavings are not interesting because the water does not reach my rice field. Therefore, I change the way of supplying water by force. Moreover, there is a Atarashii Mura Village. The villages fight each other. / At that time! While carrying water by scale, Toukichi came up with something. / "If this is done, it will be settled completely." / Based on that idea, everyone worked together to create. / This is an old story about the "cylindrical Bunsui", a facility that divides agricultural water equally. It is a facility that uses the principle of siphon to divide water equally and divides water equally by wiping it from the lower side of the Bunsui to the upper side of the cylindrical basin. It is said that there are more than facilities in Japan.
