Experience this Japanese tradition before it slips away.

The Japanese have perfected the art of onsen, or hot spring baths, for centuries. Traditionally, men and women would bathe together in the same facility, but these days the baths are segregated by gender.

Today, konyoku (mixed-gender onsen) are hard to find, with places like Tokyo having bans on such establishments. Experiencing this one-of-a-kind Japanese tradition before they disappear completely is highly recommended. Use this quick guide to find mixed-gender onsen in the central Kanto region. All of these make for a great weekend getaway from Tokyo.

Motomachi Hama Hot Spring


Also known as Hama-no-yu, this outdoor mixed onsen is one of the most popular on the Izu Islands, which are technically part of Tokyo. Swimsuits are mandatory here—good news for those apprehensive about going full commando in front of the opposite sex. This is the perfect destination for less seasoned onsen goers. You’ll have to take a boat from Tokyo to get here, but the expansive view of the ocean makes it more than worth it.

Ashitsuki Onsen


Situated right next to the sea, Ashitsuki is truly a one-of-a-kind experience. This onsen is open 24 hours a day and offers a view of the sea and nearby harbor. Bathing suits are also required here, which makes it another great introductory hot spring for those who may be a bit shy.

Miyako Ryokan (Arakawamura)


Located in Tokyo’s neighboring prefecture of Saitama, Miyako Ryokan is a fantastic place to escape the city’s busy streets and neon lights. This intimate mixed bath has a lower temperature than most onsen, clocking in at about 16°C (about 60°F). This makes it great for soaking with friends for hours on end.

Before you let your hair down and get ready to jump in the onsen, you better learn the do’s and don’ts of mixed-gender bathing.
