In Japan, a revered bathing tradition involves immersing oneself in natural hot springs, known as an onsen, as a means of relaxation and rejuvenation. This serene experience typically begins with a ritualistic cleansing, followed by a tranquil soak in the warm, mineral-rich waters. As a symbol of respect and community, bathers often follow strict rules of etiquette, separating the bathing area from living quarters. This holistic tradition emphasizes harmony with nature and the importance of cleansing the body and spirit.
Insider tip — Beni Tsubaki no Yu, the red camellia spring, is part of the Oku Yumura inner hot spring village, the highest and most deeply sourced of the Yumura district springs. The camellia imagery evokes nobility and constancy, and the deeper source produces water of greater mineral concentration than the lower-altitude springs nearby.
