In this serene bathing tradition, individuals gather to unwind and rejuvenate in a communal setting. The tranquil atmosphere is characterized by warm, soothing waters that promote relaxation and camaraderie.

The focus is on serenity, social etiquette, and a deep connection with nature and oneself.
Insider tip — Oji Onsen sits in Beppu's geothermally active basin in Oita, where silica-rich water produces the famously smooth 'bijin-yu' skin effect sought by beauty-conscious bathers. The silica coats the skin in a fine mineral veil, locking in moisture long after you towel off. Beppu's extraordinary variety of spring types means each neighbourhood bathhouse carries a subtly different mineral signature. An early morning visit before the city wakes is a meditative, steam-shrouded experience.
