Handling the Small Towel

Distinguishing Between the Big and Small

In a Japanese Onsen, you are typically provided with two types of towels: a large bath towel and a small face towel. It is important to know that these have different “active zones” within the facility.

The Small Towel (Face Towel): This is the only one you should bring into the bathing area. It is a multi-tool used for washing your body, covering up for modesty while walking, balancing on your head, and wiping yourself down before exiting.

The Large Towel (Bath Towel): This stays in your locker or on the shelves in the dressing room. It is never taken into the wet bathing area. Its sole purpose is for the final, thorough drying once you have finished your bath and returned to the locker room.

Bringing a large, heavy towel into the bathing area is considered a faux pas, as it takes up too much space and is likely to get soaked or accidentally touch the bathwater. Remembering the simple rule—“Small for the bath, Large for the dressing room”—will make you look like an Onsen pro from the moment you arrive.

The “Modesty Towel” Concept

In Japanese Onsen and public baths, you are required to be completely naked—no swimsuits or large bath towels are allowed in the water. However, this doesn’t mean there is no sense of modesty. The small “face towel” you bring into the bathing area serves as an essential tool for “Modesty Etiquette” during your transition between stations.

While walking from the locker room to the washing area, or from the showers to the bath, it is standard practice to hold this small towel in front of your body. It isn’t a strict legal requirement, but rather a characteristically Japanese way of showing consideration for others, ensuring that everyone feels comfortable in a shared, vulnerable space.

Once you are submerged in the water, you no longer need to cover up. However, whenever you stand up to move, briefly covering your front with the towel is a mark of a respectful and cultured visitor. In this context, the towel is more than just a piece of fabric for drying; it is a “sign of respect” for the community sharing the oasis with you.

No Towels in the Water

One of the most essential rules in a Japanese Onsen is: “Never let your towel touch the bathwater.” Even if your towel is brand new or has just been thoroughly rinsed, it must stay strictly outside the tub.

There are two primary reasons for this. The first is hygiene. Towel fibers can carry invisible dust, bacteria, or traces of soap, and keeping them out ensures the communal water remains clean. The second reason is the collective responsibility to preserve shared resources. In Japan, maintaining the purity of the bathwater is seen as a sign of respect for the other guests sharing the facility.

If you accidentally drop your towel into the water, quickly pick it up and wring it out at the washing station. Keeping a clear boundary between your towel and the water is the best way to ensure a harmonious experience for everyone.

Where to Put the Towel While Soaking

Since the towel must stay out of the water, you might wonder where to put it while you are relaxing in the bath. There are three common and respectful options:

1.On your head: This is the most iconic Onsen style. It keeps your hands free and ensures the towel doesn’t accidentally slide into the water.

2.On the edge of the bath: You can fold your towel and place it on a nearby rock or tile ledge. Just be careful it doesn’t slip in.

3.Back at the washing station: You can also choose to leave your towel on your stool at the washing area and only retrieve it when you are finished soaking.

The only place you should never put your towel is inside the tub itself. Choosing one of these designated spots shows that you are a mindful guest who values the cleanliness of the shared bath.

Why Put a Towel on Your Head?

In a Japanese Onsen, you will often see bathers with a folded towel balanced on top of their heads. While it may look like a quirky fashion choice, it is actually a practical “health hack” designed to prevent dizziness and overheating (known as “Nobose” in Japanese).

Soaking in hot water for a long period can cause blood to rush to your head, potentially leading to lightheadedness. By placing a towel wrung out with cool water on your head, you can help regulate your brain’s temperature and stabilize blood flow.

Conversely, in an outdoor bath (Rotenburo) during winter, bathers often use a warm towel to prevent the exposed part of their head from getting too cold, which can cause a sudden spike in blood pressure. Placing a towel on your head is more than just a classic Onsen aesthetic—it’s a smart way to manage your body’s “cooling system” and ensure a safe, relaxing soak.

The “Wringing” Etiquette

When your towel becomes heavy with water, you will naturally want to wring it out. However, the most important rule here is: never wring your towel over the bathtub. Allowing the water from your towel to drip back into the communal bath is considered unhygienic and a breach of etiquette.

If you need to wring out your towel, step out of the tub and move to the “Arai-ba” (washing station) or an area with a floor drain. If you want to re-soak your towel in cold water to cool your head, do so at a faucet and wring it out low to the ground to prevent splashing others.

The guiding principle is simple: “Do not return anything from your towel back into the shared water.” By keeping this in mind, your actions will naturally align with Japanese bathing standards. This small act of mindfulness is what helps maintain the serene and pristine environment that makes the Onsen experience so special.

Wiping Before Returning to the Locker

When you finish your bath and prepare to head back to the locker room, there is one crucial step: don’t walk through the curtain while dripping wet. In Japan, it is standard etiquette to wring out your small towel and use it to lightly wipe the excess water off your body before leaving the bathing area.

Why is this necessary? The primary reason is to keep the locker room floor dry. Since everyone walks barefoot in the dressing area, a wet floor is not only uncomfortable for others but also a safety hazard that can cause someone to slip.

You don’t need to be bone-dry; simply wiping enough so that water isn’t dripping onto the floor is perfect. Once you reach your locker, you can use your large bath towel to dry off completely. This small “pre-dry” ritual before crossing the boundary back into the locker room is a quintessential Japanese gesture of consideration for the next person.
