01 / Umankashira waterworks
The channel runs beneath the Matsuura River's bed,lifting water by the siphon principle, with no power.

Water drawn from a weir upstream on the Matsuura River is led under the riverbed in a siphon channel. Naridomi Hyogo Shigeyasu, called a god of water management, is said to have devised it and completed it in 1611 (Keicho 16). The pipe's shape resembles a horse's head, so it is thought to be named "Umankashira" (馬ノ頭).
- Said to have been completed in 1611 (city site)
- The conduit pipe changed from wooden tubs to concrete pipes (same source)
- Selected as a Civil Engineering Heritage site in fiscal 2012 (the Japan Society of Civil Engineers writes "馬の頭")
