onsen (温泉) are natural volcanic hot springs that are enjoyed for relaxation and health. as a volcanically active country, Japan has thuosands of onsen scattered along its length an breadth. onsen were traditionally used as public bathing places, but today play a central role in directing Japanese domestic tourism.
there are many different types of onsen . the major difference is the one you visit may be a natural hot spring (usually found in the mountains or somewhat countryside areas) or an imitation hot spring (which can be found in cities and hotels). traditionally, onsen were located outdoors, although a large number of inns have now built indoor bathing facilities as well.
