Onsen float

An 'onsen' is the Japanese word for hot springs. The Japanese have a long tradition of enjoying hot springs and mineral baths, particularly popular are those found outdoors. It's used to be a very common way for men in groups to share camaraderie and to make bonds of friendship and loyalty through enjoying activities that involve mutual nudity (or being nearly naked - as in the case of public street and shrine festivals).
