Every minute, 4200 liters of spring water flow from the Todoroki Water Source. Its water has been known as famous water since ancient times, and to this day, it supplies the Gosen Aqueduct, Japan’s oldest aqueduct used for clean water. In 1663, during the time of Hosokawa Yukitaka, the first lord of the Uto clan, ceramic Matsubase ware pipes were made and used as pipes for the aqueduct, and drinking water from the Todoroki Water Source was transported all over town in Uto approximately three kilometers away. 100 years later, with damage to the pipes becoming more apparent, fifth-generation Uto clan lord Hosokawa Okinori carried out a complete reparation of the aqueduct system, replacing the pipes with those made with Makado stone, a type of stone locally found in Uto. The Gosen Aqueduct is still in use today in some areas of Uto City.
