01 / Todoroki Aqueduct
Matsubase-ware pipes first carried the water;about 100 years later, Makado stone replaced them.

The water in Uto town was unfit to drink, so in Kanbun 3 (1663) Hosokawa Yukitaka, the first lord of Uto Domain, had water brought from the Todoroki spring to the town in Matsubase-ware (松橋焼) pipes. About 100 years later, the fifth lord, Hosokawa Okinori, replaced them with pipes hollowed out of Makado stone. The spring was chosen as one of Japan's 100 Famous Waters in 1985.
