In a traditional onsen, bathers follow a serene and respectful bathing tradition. Guests typically begin by washing themselves in a designated area before entering the hot spring bath. A sense of tranquility and modesty is observed, with a focus on relaxation and self-purification. Bathing naked is customary, and guests often separate by sex. The experience is meant to promote inner peace and a connection to nature, fostering a sense of community and calm among those who partake in this ancient and revered ritual.
Insider tip — 'Momiji Onsen' (maple leaf spring) at the Ayagawa-cho Social Welfare Center — a municipal facility offering hot spring bathing in Ayagawa town, central Kagawa. The combination of community welfare centre and natural hot spring is a distinctly Japanese institution, open to all residents.
