With Japan being a highly volcanic island, the Japanese have harnessed and perfected the art of onsen, or hot springs, for centuries. Traditionally, men and women would bathe together in the same facility, but it wasn’t until the beginning of the Meiji Restoration when onsen began to segregate men and women.
Today, mixed-gender onsen, or konyoku, are hard to find, with places like Tokyo having bans on such establishments. Generally, women are given towels to cover their bodies in the baths while men will bathe fully undressed. However, this dying breed of onsen can be found tucked away in the depths of the countryside or even on remote islands. With numbers dwindling, experiencing this one-of-a-kind Japanese tradition before they disappear is highly recommended.
Here is a quick guide to mixed-gender onsen in the central Kanto region.
1. Takaragawa Onsen

While mixed-gender onsen can be a unique experience, be sure to check reviews of public mixed-gender onsen, particularly admission-free onsen in nature. These baths may be an uncomfortable setting for the unseasoned bather due to lax rules.
