To keep the Tamagawa Aqueduct running, the shogunate posted mizubannin (weir keepers) at four places, including Hamura. At Hamura they patrolled and repaired the weir and sluice gates under the guidance of officials at the magistrate's office. The Sashida family served as keepers, and 226 of their documents are city-designated cultural properties, including papers on aqueduct management, river boats and the Ome Railway.

Aso Shrine, on a bluff above the Tama River, is said by the shrine's own records to have been founded in the 9th year of Empress Suiko (601). Its main hall was rebuilt in 1676 and is a Tokyo-designated tangible cultural property. The shii tree in the grounds is said to be 800 to 1,000 years old, and legend says Fujiwara no Hidesato planted it.
