Mixed onsen in Japan
A unique experience of well-being and tradition
Onsen (natural hot springs) are a veritable institution in Japan, symbolizing relaxation, culture and communion with nature. While most onsen are segregated by gender, some establishments offer mixed baths(konyoku), an ancient tradition now less common but still imbued with a unique charm.
What is a mixed onsen?
A mixed onsen, or konyoku onsen (混浴温泉), is a hot spring where men and women bathe together in the same pool. Unlike conventional gender-segregated onsen, these establishments allow for more social or family interaction, and often in an exceptional natural setting.
However, with changing mores and the westernization of Japanese society, mixed-gender onsen have become rarer. Today, they mainly attract lovers of ancient traditions and visitors curious to discover a different facet of Japanese culture.
A cultural heritage in decline
Historically, mixed onsen were the norm. Inhabitants of the same village came to wash and relax after a day's work, with no separation between the sexes. This way of life reflected a collective and natural vision of nudity, where the human body was simply considered in its primary function.
However, the influence of Western culture in the Meiji era (1868-1912) led to greater modesty in social practices, resulting in the gradual separation of baths. Today, mixed onsens are rarer and often located in rural or mountainous areas, far from the big cities.
Rules to observe in a mixed onsen
Bathing in a mixed onsen can be intimidating for the uninitiated, but following certain rules will ensure a pleasant experience for all:
- Wash before entering the bath: As in any onsen, it's imperative to shower to cleanse yourself before plunging into the thermal water.
- Wear a towel: Unlike separate onsens, most mixed onsens allow (or require) you to wear a small towel or light swimsuit for privacy.
- Respect the peace and quiet of others: Discretion is key, so avoid loud voices or inappropriate behavior.
- Accept local traditions: Each establishment may have its own specific rules, so it's always a good idea to find out before you visit.

Why choose a mixed onsen?
- Immersion in nature: Mixed onsen are often located in the open air(rotenburo), offering breathtaking views of mountain landscapes, forests or rivers.
- A unique social experience: They enable couples, friends or families to enjoy the thermal bath together, which is not possible in separate baths.
- An immersion in Japanese tradition: These establishments preserve a part of Japanese history and culture that few tourists have the opportunity to discover.
