Japan's public bath culture, centered around onsen (natural hot springs) and sento (public bathhouses), is a deeply rooted tradition. For many visitors, the idea of bathing nude with strangers can be daunting. However, this practice is a normal part of daily life in Japan, offering relaxation, health benefits, and a unique cultural experience.
Key Takeaways
- Onsen are natural hot springs, while sento are public bathhouses with heated water.
- Nudity is required in most Japanese public baths and is considered normal.
- Specific etiquette rules apply, including thorough washing before entering the baths.
- Many facilities are becoming more accommodating to visitors with tattoos.
- The experience offers relaxation and a sense of freedom from body insecurities.
The History and Significance of Japanese Baths
Onsen have a long history in Japan, dating back to the 8th century. They are mentioned in the Kojiki, one of Japan's oldest texts. These baths use geothermally heated, mineral-rich water. Historically, onsen were sacred places used for purification rituals and by the upper classes. During the Edo period (1603-1868), they evolved into social gathering spots, similar to ancient Roman baths.
Today, Japan has more than 3,000 onsen locations, according to the Ministry of Environment. These range from small local baths to large resorts. Operators must follow strict laws regarding water temperature, which typically ranges from 34 to 42 degrees Celsius (93 to 107 degrees Fahrenheit). The temperature must not fall below 25 degrees Celsius (77 degrees Fahrenheit).

Onsen vs. Sento: Key Differences
While often confused, onsen and sento have a main difference. Onsen use naturally heated spring water. Sento, found mostly in urban areas, use water that is heated artificially. Sento historically provided bathing facilities for locals who did not have bathrooms in their homes. Both types of baths are typically divided into separate areas for men and women.
Overcoming Initial Hesitation for First-Time Visitors
Many international visitors feel nervous about the nudity required in Japanese public baths. This initial hesitation is common. Stephanie Crohin, a bathhouse expert originally from France, shared her experience. "At first, I was a bit shy, not only because I was undressing in front of a friend, but also among total strangers," she said.
However, Crohin quickly realized that she was the only one focused on the nudity. "Everyone else was just scrubbing, chatting, or soaking — so I relaxed," she recalled. Years later, she developed a deep appreciation for sento, finding them to be places where people can truly forget about body insecurities. She works with the Sento Association to make bathhouses more accessible to foreign visitors.

The Social Aspect
Japanese public baths are not just about hygiene; they are also important social hubs. People gather with friends and family to relax, talk, and unwind. The mineral-rich water is believed to offer health benefits, including relieving muscle tension, improving circulation, and supporting skin health.
Navigating Bathhouse Etiquette
Beyond nudity, the specific rules of onsen and sento can also make international travelers anxious. Researching these rules before a visit can help reduce stress. One widely known rule has historically been the prohibition of tattoos.
Chanel Cai, a representative for Hoshino Resorts, explained that this rule is historically linked to associations of tattoos with organized crime. Visitors with tattoos often had to cover their ink with sleeves or bandages.
Changing Policies on Tattoos
The situation for tattooed bathers is evolving. In June, Hoshino Resorts announced a significant policy change, now permitting tattoos. The company stated its commitment to "respecting diverse cultures." Other onsen have followed suit. Additionally, many sento facilities already allow bathers with tattoos without issue.
Modern Adaptations
Some Japanese onsen and sento are adapting their policies to welcome a wider range of visitors, including those with tattoos, reflecting a growing global tourism market.
General Rules of Conduct
General etiquette in public baths focuses on consideration for others. Cai emphasized the importance of being mindful in communal areas. This includes keeping shared items clean, tidying up any fallen hair, maintaining a quiet atmosphere, and refraining from swimming or splashing in the baths. Loud talking is also discouraged.
- Wash thoroughly: Always wash your body at the shower station before entering the main baths.
- Rinse off soap: Ensure all soap is rinsed off before soaking.
- Keep towel out of water: Never let your small towel touch the bathwater.
- Tie up long hair: If you have long hair, tie it up to keep it out of the water.
- Dry before changing: Dry yourself off as much as possible before returning to the changing room.
A Step-by-Step Guide to the Bathhouse Experience
For those unsure about the process, observing others or following simple steps can make the experience smoother. Stephanie Crohin provides a clear guide:
- Remove shoes: Take off your shoes at the entrance and place them in a locker.
- Pay fee: Pay the entrance fee at the counter. (Sauna access may cost extra.)
- Undress: Enter the changing room, undress completely, and store your clothes in a locker. Bring only a small towel into the bath area.
- Wash body: Thoroughly wash your body while seated at a shower station.
- Rinse soap: Rinse off all soap before entering the baths.
- Enter baths: Enjoy the hot spring pools. Remember not to put your towel into the water. Tie up long hair.
- Sauna use: If using the sauna, rinse again before re-entering the main baths.
- Dry off: Dry yourself before returning to the changing room.
Many bathhouses provide essential items like shampoo, soap, and towel rentals, so arriving empty-handed is usually not a problem. Crohin encourages visitors to engage with locals. "Don't hesitate to chat. Even with basic Japanese or gestures, people are kind," she advises.
The Reward: Relaxation and Acceptance
The initial discomfort of public nudity often fades quickly. Many visitors find a sense of freedom and acceptance that is rare in appearance-focused societies. Hoshino Resorts, a company that started as a small family-run ryokan (traditional Japanese inn) in 1914, shares this view.
"For Western visitors to Japan who are feeling nervous about their first visit to a public bath or unsure about the etiquette, our primary advice is: don’t worry!" said Chanel Cai. She emphasized that Japanese people are not observing others' bodies in public baths; it is simply a part of daily life. Once immersed in the hot spring waters, bathers enter their own world. "There’s no need to feel self-conscious," Cai added.
The experience can be profoundly calming. Sitting in the warm water under the open sky, perhaps with snowflakes falling, allows for quiet reflection or relaxed conversation. This peaceful atmosphere often leaves a lasting impression, making future hot spring visits a desired activity for many travelers in Japan.
A Cultural Journey
Visiting an onsen or sento is more than just bathing; it is an immersion into a significant aspect of Japanese culture. Approaching it with an open mind can transform a potentially uncomfortable situation into a memorable and enriching travel experience.
