Onsen is a term that refers to the phenomenon or place where hot water (hot spring) springs from the ground, and the hot water itself. Bathing facilities using these hot springs and areas where they gather (hot spring towns and hot spring villages) are generally called hot springs. Sometimes referred to as "natural hot springs" in contrast to artificial hot springs.
