What is an Onsen? What is the difference between ‘onsen’ and ‘sento’?

In Japan, hot springs, known as onsen, are a significant part of the country’s culture. Onsen refers to natural hot springs that contain beneficial minerals and meet specific temperature requirements. These mineral-rich hot springs offer a therapeutic and relaxing experience for visitors.

Onsen can be classified as either volcanic or non-volcanic. Volcanic onsen derive their heat and mineral content from volcanic activity, typically found in regions with active volcanoes such as Hokkaido and Kyushu. Non-volcanic onsen, on the other hand, do not have direct volcanic associations.

On the other hand, sento is a public bath that uses heated tap water instead of natural hot springs. While both onsen and sento provide bathing experiences, they differ in terms of water source and overall ambiance.

Super sento establishments offer a more luxurious experience, often featuring various saunas, baths, and additional services. These modern bathhouses are designed to provide a comprehensive relaxation experience beyond traditional onsen or sento.

“When you visit Japan, make sure to try both onsen and sento to fully experience the different bathing cultures and immerse yourself in the Japanese way of relaxation.”

Whether you prefer the unspoiled natural hot springs of an onsen or the communal atmosphere of a public bath like a sento, both options offer a unique opportunity to unwind and rejuvenate in Japan’s healing waters.

How to Spot an Onsen

In Japan, recognizing an onsen is relatively straightforward, thanks to notable visual symbols and distinct entrance features. These key identifiers can help you identify and differentiate onsen from other bathing establishments.

One of the most recognizable features of an onsen is the entrance drapes, known as noren. These fabric dividers typically display traditional patterns, the name of the onsen, or sometimes even scenic landscapes. The noren add a touch of elegance and provide a sense of anticipation as you pass through to enter the onsen.

Additionally, look out for special symbols that indicate the presence of an onsen. One common symbol resembles steam rising from a hot spring (♨), representing the hot, mineral-rich waters that are characteristic of onsen. Another symbol to watch for is the character “湯/ゆ” (yu), meaning “hot water” in Japanese. These symbols can often be found displayed at the entrance of onsen establishments, helping you recognize them easily.

While onsen can be found in major cities, they are more commonly located in rural areas where natural hot springs are abundant. In these idyllic settings, you can truly immerse yourself in the soothing waters and peaceful ambiance.

How to Bathe in an Onsen

Before immersing yourself in the relaxing waters of an onsen, it’s important to understand the bathing process and adhere to proper etiquette. Following these steps will ensure a respectful and enjoyable experience.

1. Changing Rooms and Locker Facilities

Upon arrival at the onsen, locate the changing rooms where you can remove your clothes and store them in lockers provided. Some onsen may also require you to remove your shoes at the entrance, so be sure to follow the instructions.

2. Thoroughly Washing Your Body

Once you’re ready, proceed to the bathing area. Before entering the hot spring, it is customary to wash your body thoroughly. Use the showers provided and be sure to clean every part of your body. This step ensures hygiene and cleanliness for all bathers.

3. Observing Proper Onsen Etiquette

While in the onsen, it’s important to be mindful of proper etiquette to respect the space and comfort of other visitors. Here are some key points to remember:

  • Respectful Behavior: Maintain a calm and quiet atmosphere by keeping conversations low and refraining from rowdy behavior.
  • Tattoos: In some onsen, the presence of tattoos may not be allowed due to cultural associations. If you have visible tattoos, it’s best to check the onsen’s policy beforehand or cover them discreetly.
  • No Splashing: To avoid disturbing others, refrain from splashing or making excessive noise in the water.

4. Paying the Onsen Entrance Fee

Before leaving the onsen, don’t forget to settle the entrance fee. Prices may vary depending on the onsen’s location, facilities, and duration of your visit. Be prepared to pay in cash as some onsen may not accept credit cards.

“A visit to an onsen is more than just a soak in hot water. It’s an opportunity to immerse yourself in Japanese culture and relax the body and mind.”

By following these steps and respecting the onsen’s rules and traditions, you’re sure to have a memorable and rejuvenating experience. Soothe your senses and let the therapeutic hot springs wash away the stress and fatigue of the day.

Onsen Etiquette and Tips

Observing onsen etiquette is essential to ensure a pleasant experience for both yourself and other bathers. By following these tips and guidelines, you can navigate the world of Japanese onsen with ease.

1. Respect the Bathing Space

When entering the onsen, be mindful of others’ personal space. Avoid splashing or swimming in the bath, as it can disturb the tranquility of the experience. Remember, an onsen is a place for relaxation and rejuvenation.

2. Leave Technology Behind

Refrain from using phones or cameras in the bathing area. Onsen bathing is an opportunity to disconnect from the digital world and immerse yourself in the present moment. Focus on enjoying the therapeutic properties of the hot spring.

3. Tie Up Long Hair

If you have long hair, tie it up securely to prevent it from touching the water or getting in the way of other bathers. This helps maintain hygiene and ensures a comfortable experience for everyone.

4. Bring a Small Towel

It is customary to take a small towel with you into the bathing area. This towel is used for wiping off excess water before entering the changing area. In onsen culture, it is generally not used for covering your body.

5. Mind Tattoo Policies

While attitudes towards tattoos are changing in Japan, many traditional onsen still have policies against visible tattoos. If you have tattoos, it is advisable to check the rules of the specific onsen you plan to visit. Some establishments offer private baths for those with tattoos.

6. Follow Onsen Rules

Every onsen has its own set of rules regarding bathing procedures and specific etiquette. Be sure to familiarize yourself with these rules and abide by them during your visit. Signs and guidelines will be posted in the onsen area for reference.

“The onsen experience is a cherished part of Japanese culture. By observing proper etiquette and following these tips, you can fully immerse yourself in the tranquility and relaxation of the hot springs.”

Do Don’t
Respect others’ personal space Splash or swim in the bath
Take a small towel for wiping off excess water Use phones or cameras in the bathing area
Tie up long hair Touch the water with your towel

Types of Baths in Onsen

Onsen, or hot springs, in Japan offer a variety of bathing experiences with their unique bath types and facilities. Let’s explore the different types of baths you can find in onsen:

1. Outdoor Baths (Roten-buro)

Outdoor baths, also known as roten-buro, are a popular choice for onsen enthusiasts. These baths are set in natural surroundings, allowing you to soak in the soothing hot spring waters while enjoying breathtaking views of the surrounding landscapes. Whether it’s nestled among lush greenery or overlooking snow-capped mountains, roten-buro provides a serene and immersive bathing experience.

2. Indoor Baths (Noten-buro)

For those who prefer a more sheltered bathing experience, indoor baths, or noten-buro, are available in most onsen facilities. These baths are housed within the main building or a dedicated bathing area. While they may lack the scenic views of outdoor baths, indoor baths often provide a cozy and private atmosphere, allowing you to relax and rejuvenate in the warm mineral-rich waters.

3. Public Baths (Sento)

In addition to onsen, Japan also has public baths called sento. Unlike onsen, sento use heated tap water instead of natural hot spring water. Sento baths are typically found in urban areas and offer an affordable bathing option for locals and tourists alike. While they may not have the same mineral content as onsen, sento baths provide a relaxing and communal bathing experience.

4. Super-Sento

If you’re looking for a more luxurious bathing experience, consider visiting a super-sento. These establishments offer a wide range of facilities, including multiple baths, saunas, steam rooms, relaxation lounges, and even restaurants. Super-sento provide a comprehensive wellness experience, allowing you to indulge in various spa and recreational activities in addition to bathing.

5. Specialized Baths

Within onsen and sento facilities, you may also find specialized baths that cater to specific preferences. Some examples include:

  • Ashi-yu (Foot Bath): These baths are designed for soaking and massaging the feet. It’s a popular option for tired feet after a day of exploring.
  • Utase-yu (Waterfall-style Bath): Utase-yu features a powerful stream of hot spring water cascading onto bathers, providing a unique and invigorating bathing experience.

No matter the bath type you choose, each offers its own distinct charm and therapeutic benefits. Whether you prefer to soak in the tranquility of an outdoor bath, enjoy the comforts of an indoor bath, or explore the communal atmosphere of a sento, Japan’s onsen culture has something for everyone.

When visiting an onsen in Japan, it is advisable to bring your own toiletries, including shampoo, soap, and hair ties. Most establishments provide amenities, but the quality may vary. It is also recommended to bring two towels: a larger one for drying off after bathing and a smaller one for wiping excess water. In some cases, towels can be rented or purchased on-site. Optional items, such as an akasuri (skin scrub towel) for exfoliation, can enhance your onsen experience.
