35°37′N 139°24′E / 35.617°N 139.400°E / 35.617; 139.400 Tama Hills (多摩丘陵, Tama-kyūryō) is an area of hills stretching across southwest Tokyo^[1] and northeast Kanagawa Prefecture in the Kantō Plain on Honshū, Japan. Its total area is approximately 300 km². The Tama River marks its northeastern boundary. The Tama Hills border the Sagamino plateau.

It straddles the municipalities of Hachiōji, Hino, Tama, Inagi, and Machida cities in Tokyo, and Kawasaki and Yokohama cities in Kanagawa.

The area is dotted with remains of Jōmon period hunter-gatherer settlements.

The area had been developed extensively since the 1950s to support demand for housing around rapidly expanding Tokyo and Yokohama. The hills are now mostly a patchwork of new residential suburbs and low, forested hills and pockets of remaining farmland. Some fairly large areas of forests still exist in places. Most notable among the housing developments are Tama New Town and Kohoku New Town.

The build-up of the area is a key plot element to the Studio Ghibli film Pom Poko.^[2]
