ONSEN VS. SENTO: FIND YOUR PERFECT BATH EXPERIENCE

Feb 15, 2025

BY Chisato Takahashi

In Japan, I took a bath every day at my parents’ house. It warmed my cold body in winter, and it washed away the sweat and refreshed me in summer. I believe that every Japanese person loves taking baths. Also, rehydrating with chilled milk or beer afterward used to be my favorite part.

Recently, many tourists have been looking forward to experiencing the Japanese hot springs. However, some might be concerned about whether they can enter the onsen because of their tattoos.

If so, no worries. Here, we will explore Japanese hot springs and public baths together.

What is Onsen and Sento?

In general, there are two types of baths called Onsen and Sento.

Onsen is a hot spring that naturally gushes up from underground and has been cherished by the Japanese since ancient times. The reason why Japanese people love Onsen is due to its amazing healing power for various illnesses and injuries. For more detailed information about the types and benefits of Onsen, you can check out this blog.

In addition, Sento is a public bathhouse that retains a nostalgic charm. It became popular among common people during the Edo Period when most households did not have private baths. Therefore, Sento was essential for daily life. However, after the 1970s, private baths became common, and the number of Sentos decreased from about 18,000 to around 1,800.

The main difference between Onsen and Sento lies in the water quality. For instance, Onsen must meet strict legal standards regarding mineral content and temperature, using natural spring water. In contrast, Sento typically uses heated tap water. Simply put, the difference is whether the water is natural or artificial.

Also, the price of Onsen depends on location, while Sento fees are regulated and standardized within each prefecture. This regulation allows Sento to receive subsidy aid from local governments, such as a discount on water.

Interestingly, some Sentos use natural hot spring water but charge the same fees as regular ones. So, you can choose between an Onsen or Sento based on your preferences and purposes.

Personally, my mother and I are Onsen lovers, but my brother is a Sento enthusiast. He finds the retro atmosphere of Sento fascinating not only because it is affordable but also because it attracts locals, giving a unique insight into the community’s vibes.

Unfortunately, most Onsen in Japan do not allow tattoos. However, many Sento, such as Takarayu in Kita-Senju, Tokyo, are tattoo-friendly. So, people with many tattoos might find Sento a great option.

However, some Onsen, especially Tokyo, sell cover-up stickers that allow entry if the tattoos are invisible, so please make sure to check the websites of your preferred Onsen policies!

As you can see in this blog, each hot spring offers various benefits, such as treating skin inflammations, menstrual pain, and muscle pain. Therefore, if you are concerned about your health or seeking relaxation, find an onsen that suits your needs and give it a try!!

When it comes to Sento, there are a few items that many Japanese people immediately think of when they think of public baths, which are the Kerorin bucket and the rubber duck. Just having these items can make you feel like a Japanese person who loves Sento culture, and I highly recommend them. In fact, I also have them!!

Furthermore, the etiquette and manners for using the bath are the same for both Sento and Onsen. You can prepare for it by checking the tips in this blog. Please note that it is a good idea to bring your own toiletries, such as shampoo, conditioner, and cosmetics, even if some places offer rentals or sell these items.

I hope you found the perfect bath experience that suits your needs.

Onsen

Kusatsu Onsen, Gunma: “Onsen heal everything but lovesickness”

The hot springs of Kusatsu Onsen are known for their strong sterilizing power, which is effective for neuralgia, cuts, fatigue, and even for skin beauty. Moreover, there are numerous hot spring facilities such as Otaki no Yu, Goza no Yu, and West Riverside open-air bath, but my top recommendation is the last one.

West Riverside open-air bath features a magnificent outdoor bath like a pond surrounded by forests, offering incredible views. However, you cannot wash your body with shampoo or other products, so be sure to rinse off your body with hot water before entering.

Additionally, every Friday evening, the male bath changes to a mixed-gender one. Therefore, it’s recommended for those who prefer not to enter naked, are a couple, or families. Why not enjoy this hot spring experience, which is overflowing with a sense of spaciousness in Gunma?

Gero Onsen, Gifu: “Experience the tatami baths”

Gero Onsen is known for its soft, alkaline, simple hot springs located in Gifu Prefecture. It is one of the most famous hot springs in Japan. Among their options, I highly recommend Ogawa ya, a long-established ryokan.

Ogawa ya not only offers accommodations but also day trips to the hot springs. One unique point of this place is its incorporation of tatami culture. By utilizing tatami, which is a flooring material loved by the Japanese for a long time, Onsen created a comfortably authentic traditional atmosphere. The combination of soft tatami and hot springs allows guests to immerse themselves in Japanese culture and also relieve the stresses of daily life.

Moreover, the women’s outdoor Onsen has a white ion bath and is perfect for those seeking baby-soft skin. In addition, the men’s bath boasts warm sunlight in the morning and a mystical illumination at night, creating a truly special time for bathing.

When you visit Gifu, be sure to check out this hot spring map and treat your tired body!!

Dogo Onsen, Ehime: “The oldest hot springs in Japan”

Next, let me introduce Dogo Onsen, where you can enjoy three different hot springs.

Firstly, Dogo Onsen’s Main Building is a historical bath facility of approximately 3,000 years old and designated as an Important Cultural Property located in Matsuyama City, Ehime Prefecture. Also, the elegant wooden architecture is the official model of “Spirited Away” from Ghibli. The mild, alkaline, and simple spring water is definitely perfect for those with dry or sensitive skin.

Second is Tsubaki no Yu, which is loved by locals. The high ceilings and huge bathing areas come at a more affordable price compared to other hot springs.

Third, there’s Asuka no Yu. It is an art-style hot spring with a concept inspired by Ehime’s traditional crafts. You can enjoy the hot springs for healing the skin, the nice temperature and aroma, and also admire Ehime’s crafts visually. This makes it a great choice for those with limited time for sightseeing.

Sento

Togoshi Ginza Onsen: “Beauty Bath”

This place is a Tokyo Sento that reminds me of a nostalgic Japan while also being modern and user-friendly. The hot spring water is popular among women for its skincare effects. Additionally, the baths for men and women are different, but they change places daily, allowing guests to experience both.

Kaisei Yu: “Carp and black hot spring”

In addition to its retro interior, this bathhouse has a fantastic aquarium with carp in the wall. Moreover, it has carbonated black hot spring baths. These exceptionally rich black and white hot springs are the pride of Kaiseiyu.

After bathing, your skin texture will be smooth and silky. So, after a day of exploring Tokyo, I recommend you stop by here for a refreshing experience.
