丹沢山地
Atsugi is located in the hilly center of Kanagawa Prefecture, approximately 45 kilometers from central Tokyo or 30 kilometers from central Yokohama. It is located at the northern end of the Sagami Plain created by the Sagami River, which originates from Lake Yamanaka, and straddles the Tanzawa Mountains in the west and the plain on the west bank of the Sagami River to the southeast. The Nakatsu River and Koayu River, which originate from the Higashitanzawa Mountains, join the Sagami River, which forms the border with Ebina, Zama, and Sagamihara. Parts of the western portion of the city are within the Tanzawa-Ōyama Quasi-National Park and include Mount Ōyama.
