In a traditional Japanese onsen, visitors immerse themselves in a serene atmosphere, where relaxation and rejuvenation are paramount. Guests typically disrobe and store their belongings in a designated area before entering the baths. The onsen is a communal space where people from all walks of life come together to unwind and socialize. Respect for others and adherence to traditional etiquette are essential, as guests strive to create a tranquil environment for all.

Insider tip — Kannon Yu at Kusayama Onsen serves the ancient castle town of Tambasasayama whose preserved Edo-period merchant streetscape in the Nishimachi district constitutes one of Japan most complete samurai city heritage zones. Tambasasayama is the heart of the Tanba highland region whose volcanic upland soil and cool mountain climate produce the premium black soybeans (kuromame) and matsutake mushrooms that define Tanba cuisine — the kuromame of Tanba commanding prices of 10,000 yen per kilogram at Kyoto markets during the New Year season.
