Hamura, in the western Tokyo Metropolis at the bend of the Tama River where the Yazawa weir channels the river into the Hamura Water Intake facility — one of the key historical infrastructure works of the Meiji period that brought clean water to Tokyo — is a small city of just over 57,000 whose river heritage and traditional Hamura Tanabata Festival create a pleasantly small-town character within the Tokyo metropolitan boundary. Hamura Onsen Tokyo draws on sodium and bicarbonate thermal waters from the geothermal resources of the western Tokyo Tama River zone, providing restorative baths in a riverside community whose Meiji-era water infrastructure heritage, the scenic Tama River Yazawa weir area, and the traditional Tanabata festival decorations create an appealingly modest and human-scale spa setting at the western edge of Tokyo Metropolis. The Hamura Water Intake historic site, the Tama River weir and riverside cycling paths, and the Hamura Tanabata Festival celebrated each August with traditional Edo-period paper decorations create a gently traditional and riverside spa destination at the far western edge of the Tokyo administrative boundary.
