The onsen is basically a Japanese public bath (sento) that uses natural hot spring water. Its history and etiquette are closely related to the sento.

The sento plays an important role in Japanese culture, and provides socially institutionalised relief from the pressures and stress of contemporary work and life-style. Over and above the physical wellbeing, bathing in an onsen also gives individuals a natural possibility to break down the hierarchical social barriers through mutual nakedness.

Managers’ understanding and commitments are enhanced, and new insights into the company and its environment are strengthened through the process of shared experience with other corporate members.
