Japanese onsens are more than just hot springs—they’re a slice of local life. It’s a place to unwind and a uniquely Japanese experience with healing powers.

KAI Yufuin (Yufuin Onsen, Oita Prefecture)
Go All In—Swimsuits Aren’t Allowed
Let’s start with this: Japanese onsen culture is a “go nude or go home” deal. Onsens are always gender-segregated, and you’ll spot a red curtain for the women’s side and a blue one for the men’s. It might feel strange at first, but everyone’s doing it, and no one’s watching. You’ll be relaxed in no time.
Shower Before You Soak
Once you’ve undressed in the locker area, head to the washing area before you hit the tub. Here, you’ll find a small stool, a handheld shower, and soap. Just take a seat, wash up thoroughly, and rinse off completely. This pre-soak scrub is a key part of onsen etiquette, and it’s all about keeping the water clean and pleasant for everyone.
Bring a Small Towel (But Keep It Out of the Water)
Most people bring a little towel, which is handy for dabbing off after the bath—but it’s a big no-no to let it touch the water. To keep the bath pristine, some people fold their towels and leave them on the side. Others go for the classic Japanese look by placing it on their heads. Choose your style!
Keep Your Hair Out of the Water
If your hair is long, tie it up. It’s not just good etiquette—it’s easier for you to relax when you’re not fussing with stray strands.
Try the Cold Towel Trick to Avoid Overheating
Onsen water is usually hot, and while that’s part of the charm, it’s easy to feel a bit overheated. Here’s a pro tip: soak your towel in cold water and place it on your head. Locals swear by this to keep cool, and it’s a great way to avoid that lightheaded feeling.
Soak Up the Onsen’s Health Benefits
Minerals in onsen water aren’t just for show—they’re famous for soothing skin, relieving muscle tension, and improving blood circulation. Take a deep breath, let yourself float a little, and enjoy the rejuvenation.
Pat Dry Before Heading Out
Before you leave the bathing area, use your small towel to lightly pat down and avoid dripping water on your way back to the locker area. Once you get to your locker, you can fully dry off using a larger towel and change.
Finish Your Experience with a Bottle of Cold Milk
After a hot soak, many Japanese people finish the ritual with a cold glass of milk, sometimes right from the vending machine. Whether you pick plain, strawberry, or coffee flavored milk, this post-onsen drink tradition is one worth trying.It’s the perfect way to cool off and end your experience.
Here’s a bit of extra advice for the smoothest onsen experience:
An onsen isn’t just a bath; it’s a ritual that allows you to reset and create lasting memories. Let go, relax, and allow the experience to recharge you. With these tips, you’re ready to embrace the full onsen experience—a journey that’s warm, welcoming, and truly unforgettable.
