Why should small towels stay out of Japanese hot spring baths? Learn the hygiene reasons, how others perceive it, and the proper way to use, place, and handle towels.

In Japanese hot springs, you may bring a small towel into the bathing area, but you should not put it in the tub. You may hold it while soaking, but you should not submerge it or wash your body with it in the bath.
The short answer is that this helps prevent towel lint, soap residue, and dirt from mixing into the shared water, and it also avoids making other bathers feel that the water has been dirtied. Once you understand the reason, the solution is simple: keep the towel outside the bath. In this article, we explain why towels are frowned upon in the water, then cover the proper ways to place and use a small towel, how to handle a large bath towel, and towel etiquette in the sauna, all with one clear focus: don’t put towels in the water. You can also check the full bathing flow in The Basics of Hot Spring Etiquette and How to Bathe.
In Japanese hot springs, the tub is not a place to wash yourself. It is a place to warm up after you are already clean. Even the Ministry of Health, Labour and Welfare’s hygiene guidelines for public bathhouses state that facilities should encourage bathers to wash thoroughly before entering and keep the bathwater clean as a shared standard. Not putting a towel in the water is a natural extension of that idea: do not dirty the bath.
There are roughly three reasons.
| Concern | What happens |
|---|---|
| Lint and fibers | Towel fibers loosen and float into the water as tiny threads |
| Soap or detergent residue | Laundry detergent or body soap can dissolve into the bathwater |
| Dirt from wiping the body | Sweat, oil, and dust on the towel can touch the clean shared water |
One important point: these hygiene concerns are widely discussed, but they are not legally prohibited. The Japan Spa Association also notes that claims about dirty towels or loose fibers are commonly cited explanations, but they do not have a legal basis.
So the bigger reason is how other users feel. In a bath shared by many people, even seeing a towel in the water can make others feel that the bath has become dirty. To protect both actual hygiene and the sense that everyone can relax comfortably, many facilities tell guests not to put towels in the water. This is less a strict rule of etiquette than a shared-space courtesy.
A small towel brought into the bathing area, such as a tenugui or face towel, does not have one single correct placement as long as it stays out of the water. Here are the standard ways to handle it.
| How to use it | Point |
|---|---|
| Place it on your head | The most common method. Fold it and rest it on the crown of your head so it does not hang into the water |
| Put it on the tub edge | Place it on a dry edge or stone where it will not touch the water, and make sure it will not slip in |
| Hold it above the water | Fine for a short time, as long as you keep it above the surface |
Putting the towel on your head also helps prevent overheating. The Kinosaki Onsen Tourism Association recommends this method during bathing, and says a warm towel in winter or a cool towel in summer can make bathing more comfortable. That said, this is for comfort, not a hygiene rule.
Whichever method you choose, the only thing that really matters is not submerging the towel in the bath. You do not need to fold it perfectly or place it in a specific spot. If it stays above the water, you are fine.
Outside the tub, the small towel does its normal job. Use it to wipe your body lightly after rinsing in the washing area, or to dry yourself a bit when leaving the bath. Just because you should not use it in the tub does not mean you cannot use it in the bathing area at all.
If you feel awkward walking around nude, it is common to hold the towel in front of your body while moving between the washing area and the bath. This is a natural gesture in Japanese bathhouses and is perfectly acceptable. However, when entering the tub, make sure the towel does not touch the water: place it on your head or on the edge. Covering yourself and keeping the towel out of the bath can go together. If you are especially shy about nudity, see First-Time Hot Spring Tips for People Who Feel Embarrassed About Being Nude.
If the towel has been used in the washing area, it may contain soap, so wringing it lightly before bringing it near the tub helps prevent drips from bothering anyone.
A single small towel is usually enough to bring into the bathing area. A large bath towel is typically left in the changing room basket or locker. After leaving the bath, you first use the small towel to dry yourself a little near the bath exit, then finish drying with the large towel in the changing room.
This also helps keep the bathhouse floor and changing room as dry as possible. If you think of it as “the changing room is for preparation and finishing, and the bathing area is for bathing,” it becomes easier to decide where each towel belongs. In general, you do not bring a large bath towel into the tub area.
In sauna facilities, it is considered hygienic to sit on a towel or mat rather than directly on the bench. This prevents sweat from soaking into the seat and is another form of consideration for others.
When moving from the sauna to the cold plunge bath or hot spring tub, the same idea applies as in the bathing area: do not submerge a sweat-soaked towel. Place it on your head or on the edge. Rinsing off sweat with a quick shower before entering the cold plunge also helps keep things cleaner. You do not need a separate towel just for the sauna, but the rule remains the same: do not put a sweat-soaked towel in the water.
Some visitors to Japan feel that towel handling is a very strict rule. But what you really need to remember is just one idea: do not put the towel in the water. Instead of searching for the perfect placement, simply keep it out of the bath, and you will be fine.
Even if you accidentally dip it in the water, there is no need to panic. Just take it out and place it on your head or on the edge again. Towel etiquette is not about perfection; it is a small act of courtesy for sharing the same bath.
To avoid lint, soap residue, sweat, oil, and other dirt from mixing into the water. Another major reason is that other bathers may feel the water has become dirty if they see a towel in the tub.
Place it on your head or on a dry edge that does not touch the water. You may also hold it above the surface. It does not need to look neat; the important thing is simply to keep it out of the water.
Yes. Holding the towel in front of your body while walking between the washing area and the bath is a common gesture. When entering the tub, place it on your head or on the edge so it does not touch the water.
Usually not. Keep the large bath towel in the changing room, and bring only a small towel into the bathing area. Use the large towel after you get dressed.
No. Do not submerge a towel that has absorbed sweat. Place it on your head or on the edge instead. The same basic rule applies as with the bath tub.
In Japanese hot springs, towels are kept out of the tub to avoid mixing lint, soap residue, and dirt into the shared water, and to help everyone feel comfortable and safe. This is less a legal ban than a courtesy that has become standard in shared bathing spaces.
The one rule to remember is simple: do not put the towel in the water. A small towel may go on your head or on the edge, and it can also be used to cover the front. Keep the large bath towel in the changing room, and do not put a sweat-soaked sauna towel in the bath either. Instead of worrying about the perfect placement, just keep the towel outside the water, and even first-time visitors will not get confused.
