Zama Onsen is a practical hot spring facility in Zama city, a compact urban municipality in central Kanagawa Prefecture best known for housing Camp Zama, the headquarters of the United States Army's Japan operations — a presence that has given the city a distinctive bicultural character over seven decades. The bicarbonate mineral waters provide gentle warmth and skin-softening benefits, offering accessible thermal relaxation for the city's mixed residential community. The surrounding Sagami River valley and Kanagawa countryside visible from the city's hillsides provide a pleasant natural backdrop to what is essentially a convenient urban onsen serving the daily wellness needs of a suburban Kanto community.
