What to Bring to an Onsen: Hot Springs Packing List

Ever wondered what to bring to an onsen? I used to ask myself the same thing before my first visit. The truth is, not much at all.

Onsen are meant to be simple, and your packing should be too. Over time, I’ve worked out the few essentials that make the whole experience more comfortable without weighing you down.

If you’re putting together your own onsen packing list, here’s exactly what I recommend so you can just relax and enjoy the soak.

Onsen packing list

Over time I’ve cut it down to a small list that works whether I’m at a ryokan or a day-use onsen (higaeri onsen). I use this same list in big onsen resorts like Beppu and in smaller local bathhouses too. These are the things I never skip:

• A small towel: Use it for modesty on the way to the onsen baths and for drying afterward. Just remember it never goes in the water.
• Hair ties: If you’ve got long hair, tie it up to keep the bath water clean.
• Coins for the locker: Most places have lockers, and many still take 100 yen coins. I always carry a spare.
• A bottle of water: You’ll feel thirsty after a soak, and having water ready makes a big difference.
• A plastic or zip bag: Perfect for carrying a damp towel so the rest of your things stay dry.
• Some cash: Day-use onsen often ask for payment in cash, and vending machines inside usually do too.
• A large towel (optional): Some onsen resorts rent them, but if not, it’s worth bringing your own.
• Moisturizer and skincare: Onsen water leaves your skin feeling soft, but I always like to follow up with a little lotion and a basic skincare routine so my skin doesn’t dry out afterward.
• Hairbrush or comb (optional): Many bathhouses provide hairdryers but not brushes. I like having my own.
• Change of clothes (optional): Slipping into something fresh after your soak feels amazing, especially if you’ve been traveling all day.
• Tattoo cover (if needed): Some public onsen are strict about tattoos. A small patch or cover-up can make things easier if you’re not visiting a tattoo-friendly onsen. Always check ahead though!

That’s it. A short, simple onsen packing list that works every time.

What you can skip at an onsen ryokan

If you’re staying at an onsen ryokan, you can pack even lighter. Ryokan almost always provide yukata, slippers, towels, and bath toiletries. Some even add skincare or hair dryers.

The only thing I still bring is my own small towel, just because I like it. Everything else is waiting for you, so your Japanese onsen experience feel very easy.

What to bring to an onsen if you travel with kids

Onsen with kids can be a lot of fun, but a little preparation goes a long way. Here’s what I’ve found useful:

• Extra small towels, because kids splash more.
• A quick-dry towel or poncho to warm them up fast.
• Drinks and snacks for after the soak.
• Plastic bags for wet towels or accidents.
• A small toy if the onsen is family-friendly and allows it.

I also keep soaks short with little ones. Ten minutes is usually enough, and it keeps the visit enjoyable for everyone.

Seasonal onsen packing tips

What you bring changes a little with the seasons, and this guide wouldn’t be complete without a few seasonal tips.

In winter, a warm hat or wrap makes sitting in a snow onsen so much more comfortable. In autumn, an extra towel helps when the air feels cool after your soak.

Spring is warmer, but I like to pack a change of clothes so I feel fresh afterward. For summer, I suggest going in the morning or evening and bringing extra water to stay hydrated.

On rainy days, I always carry a compact umbrella, since paths can get slippery.

What not to bring to an onsen

It’s just as important to know what not to bring. These things only get in the way:

• Phones and cameras: Onsen are no-photo zones.
• Swimwear: Unless the sign says otherwise, everyone bathes nude.
• Soaps and shampoos: You wash at the shower stations, never in the bath.
• Valuables: Keep them at home or in the lockers.
• Big bags: Changing rooms are small, so keep it light.

Before you go

Before you finish packing, it’s worth knowing a little more about onsens and ryokan experience.

If you’re comparing accommodation, my post on Ryokan vs hotel will help you decide what’s right for your trip.

Not sure how long to book? How long to stay in a ryokan explains whether one night is enough or if a slower pace is worth it.

And since food is a highlight, don’t miss Ryokan meals for a peek at the kaiseki dinners and seasonal breakfasts you can expect. Finally, if you’re curious about the cultural side, my post on Omotenashi will give you insight into the hospitality that makes ryokan stays feel so special.
