In a traditional Japanese onsen, bathers immerse themselves in a serene and tranquil environment, seeking relaxation and rejuvenation. The bathing tradition emphasizes communal respect, cleanliness, and modesty. Guests typically wash and clean themselves before entering the hot spring bath, and separate bathing areas are often provided for men and women. A soothing atmosphere and tranquil surroundings foster a sense of calm and well-being, allowing bathers to unwind and disconnect from the stresses of daily life.
Insider tip — Shinmei, the divine name of the Shinto spirit, consecrates this Kai spring in the Yumura district, a cluster of hot spring facilities at the western edge of Kofu. The water is celebrated for its smooth texture, and the nearby Shingen-ko Festival each spring brings Kai's samurai heritage to life with armoured processions.
