Mixed Onsen in Japan

23 Mixed Onsens in Japan (For Couples and Families!) [2022]

Looking for a mixed onsen in Japan?

Mixed baths in Japan, konyoku (混浴) are mixed gender or communal coed hot springs where all guests can enjoy soaking together with their companions in one onsen.

Have you always wanted to enjoy hot springs as a couple or family, but accommodation with en-suite private onsen are beyond your budget?

You may want to consider going for a Japan mixed onsen experience, at more affordable prices!

Some even boast large, open-air outdoor hot springs (rotenburou, 露天風呂) with scenic views, reminding us of the best onsen in Hokkaido.

It ia an amazing experience at lower prices, but to be naked in an onsen with strangers… of the opposite gender?! I understand.

Luckily for us, there’s this nifty invention: wearable towel with straps!

In Japan, mixed onsens will usually provide these towels for the comfort, convenience and privacy of guests enjoying the hot springs.

Onsen enthusiast Wen  is going to share all the best mixed gender onsens throughout all regions in Japan, so we can steam ourselves like happy dumplings!

If you’re still disappointed there’s no mixed bath onsen in Kyoto, let the beautiful outdoor onsen facing Ohto River in Wakayama at Sansuikan Kawayu Midoriya cheer you right up. 

There’s a large mixed onsen with a view of the Ohto River and an outdoor onsen on the riverbank surrounded by the nature of Kumano, another natural river hot spring.

The Kawayu Onsen winter specialty “Sennin Furo” (1000-person bath) is about a 7-minute walk away. 

The water source of about 65°C springs from the bottom of the Oto River, and the temperature adjusts to about 40°C from December to the end of February. A natural wonder of river hot springs.

FAQ 

Are There Mixed Onsen In Japan?

Yes, there are mixed onsen in Japan – known as konyoku in Japanese. Konyoku describes a mixed onsen (hot spring) in Japan and while they are still around, hot spring expert Kyoko Kitade said mixed onsen was practiced at only about 500 hot spring inns and communal baths across Japan in 2021, down from 1,200 or so in 1993.

Do You Have To Be Naked In Mixed Onsen?

Yes, everyone (male/female) is naked in mixed onsen while in the water but in Japan, onsens for mixed gender will provide wearable towels with straps (known as yugi, 湯着) for your comfort and privacy. Although uncommon, a few places also allow or even provide rental swimsuits for guests.

How Do Mixed Baths Work In Japan?

In Japan, onsen mixed baths work in such a way that the women have their own bath but can join the men on their side if they are so inclined. Most baths provide gender-segregated changing rooms and towels for everyone to cover up before entering the mixed baths. Towels can be optional when the water is milky and opaque.

Mixed Onsen Etiquette: Differences?

Regular onsen etiquetteMixed onsen etiquette
Au naturale, no towels allowedWearable towels or swimsuit allowed
Avoid staring; accidental glances OKAbsolutely NO staring or straying glances
Keep chatting to a minimum, low volumeRefrain from chatting up naked strangers

And of course, remember to always shower and wash yourself clean before entering the onsen – for hygiene and courtesy. 

Ladies (and gentlemen) with fabulous hair past your shoulders, keep your tresses up and out of the water with a stylish, comfortable hair band or hair towel. For safety, dry properly in the bath area before leaving.
