Obara-juku Honjin on the Koshu Dochu stood in the residence of the Shimizu family, who served as nanushi (village headman) and toiya (post-town official). The city records it as the only surviving one of the 26 honjin in the prefecture. Though the roof is now sheet metal, the kabuto-style roof remains on the east side, showing features that reflect sericulture in the Tsukui area.

  • 4-tier kabuto-style roof

The Ishii Family Residence in Midori Ward was designated a national Important Cultural Property in 1971. An ink inscription of Hoei 4 (1707) on a beam above the earthen floor of the main house fixes its date of construction. The city writes that its floor plan differs from the prefecture's mainstream and seems influenced by the Gunnai region of Yamanashi Prefecture to the west.

The Sagamino Baseline was measured in 1882 (Meiji 15) and adopted in May 1883 as a reference line for modern surveying. Its north end point, a city-designated historic site, is in Asamizodai, Minami Ward, and the south end point is in Zama City. The city notes it is also said to be the birthplace of modern maps in Japan.
