Onsen
温泉
An onsen is a public bath with natural hot spring water, and its history and etiquette are closely related to the sento (communal bath house) . The essential difference between an onsen and a sento is that the water in an onsen must be volcanic spring in origin, even if reheated, whereas a sento may use ordinary heated water. The onsen plays an important role in Japanese culture, providing socially institutionalised relief from the pressures of the contemporary Japanese twelve-hour work ethic and a chance for Japanese to break down the hierarchal nature of society through the mutual nakedness of skinship. Essentially, the onsen should be the diametric opposite of everything in normal, hectic day-to-day Japanese life.

Ideally, they should be outdoors, use naturally hot water directly extracted from a natural volcanic spring, and they are often embellished with (or, in the cheaper varieties, replaced by) a wide variety of extravagant spa baths, artificial waterfalls and saunas. Onsen water is often thought to have healing powers according to its mineral properties and onsen often have several different baths, each augmented by the addition of different minerals or the composition of the tub.
In the mountains of Nagano, groups of wild Japanese monkeys are living in Jigokudani Yaen-koen. They are Snow Monkeys and have learned how good having a bath is.

“Mmmm, I start getting dirty”
Even though the monkeys seem friendly, it’s important to follow these rules when you find them.
- Observe the monkeys from the distance.
- Do not stare them in the eyes.
- Do not put your hands out or try to touch them.
- Do not show or give food to monkeys.
