A Beginner’s Guide to Sento



A Beginner’s Guide to Sento


by guest writer Stephanie Crohin (sento journalis)

Sento or public bathhouses are an attractive part of the history of Tokyo, and fortunately there are many still in operation in the city. With architecture resembling that of temples or shrines, large murals of Mt. Fuji, noren curtains, and attendant booths, sento carry the “good old times” of Tokyo into the present. Indeed, they remain a part of everyday life for many residents of the city, and are a source of fascination for both foreign tourists and foreign nationals living abroad. This is particularly true for Stephanie Crohin. Born in France, she now works as “sento journalist.” In this article, she explains basic sento knowledge as well as how to use a sento.

About bathing in Japan

Myojin-yu sento
Myojin-yu, a sento that has been loved by the locals for more than sixty years.

With a history spanning hundreds of years, sento once occupied a central role in the lives of Japanese. In 1968 there were over 17,000 sento in operation in Japan, but now that number has dropped to approximately 2,600. The culture of bathing first appeared in Japan in the 6th century as a teaching of Buddhism. Though the bathing practices in Japan have taken various forms throughout the different periods of history, eventually evolving into the sento of today, bathing remains an integral and beloved part of Japanese culture. 

What is the difference between a sento and an onsen?

Those not from Japan might wonder about the difference between a sento and an onsen. To put it simply, an onsen or natural hot springs refers to a natural source of hot or mineral water which has a specific mineral or chemical composition. In contrast, a sento is simply a facility established for bathing, and most use regular water drawn from pipes or a well. However, there are some sento that use water from hot springs. It’s not a well-known fact, but there are quite a few sento that draw their water from natural hot springs in Tokyo. 

Good manners for entering sento

To start, here’s a piece of information that will likely make many readers from different countries very happy. While there are many onsen that ask that visitors with tattoos not use their facilities, public sento generally do not have such rules. Out of the 600 plus sento that I have visited, only two or three of them had rules against tattoos. (Note: facilities designated as “super sento” often prohibit guests with tattoos from using their facilities, so please check prior to visiting.) 
Shoe lockers at sento
Depending on the kind of locker, the keys may be made of metal or wood. 

1) There are lockers for your shoes at the entrance of the sento. You cannot wear your shoes inside the facility, so please take them off in the entryway and put them in an open locker. Be sure not to loose the key!

2) You’ll see that there’s a place to pay the fee for using the facilities near the entrance. Like the picture above, many facilities have this kind of desk called a bandai. You can also purchase or rent items such as towels, soap, or shampoo here.

3) Head to the dressing room, take off your clothes, and put them in an available locker. Note: you will need to dry off before re-entering the dressing room after bathing, so please bring a small towel with you into the bathing area. 
Arai-yu Sento
The red faucet is for hot water and the blue one for cold. You can mix the water in your bucket to get the perfect temperature. 

4) When you enter the bathing area, take a bucket called an oke and a stool and head to an empty karan, or place with a faucet. You can tell if a spot is open or not by checking to see if there is already a bucket, stool, or personal items like shampoo there. If there is something already there, choose a different spot. 

5) When you finish bathing, return your stool and bucket, dry off with your towel, and head back into the dressing room. Be sure to dry off as best as you can before heading back into the dressing room so as not to get the floor wet and inconvenience other guests.

Good manners for inside the bathing area
・Don’t enter the bath without washing off first.
・Please be courteous of other bathers when washing up
・Please rinse any soap, shampoo, or conditioner from the floor
・Even if a handheld showerhead is provided, please sit down to wash up.
 (Note: some sento will only have faucets rather than showeheads.)
・Individuals with long hair should pull their hair back with a hair elastic or clip before entering the bathtub to avoid getting hair in the water.
・Please do not bring towels into the bathtub even if they are clean.
・Should you use the sauna, please be sure to wash off again before entering the bathtub. Do not enter the tub sweaty.
・Do not dive or swim in the bathtub. 

As you can see, the rules and manners for sento aren’t particularly hard. Probably the most important thing to keep in mind is to be considerate of others. If you are, then you shouldn’t have any problem enjoying your sento experience. 

Things that are good to bring

Ichi No Yu Sento

Recently, a number of sento have towels, shampoo, body wash, and so on that you can borrow or purchase, meaning you can go to a sento tebura, literally empty handed. However, it is a good idea to bring with you your personal skin or hair care items if you have preferences about the kind of products you use. Bringing them in a small pouch is a convenient way to carry them. 

Great things about sento

Health and beauty benefits
Shinsei-yu Sento

First up on the list of the many benefits of sento are those relating to health and beauty. Bathing at sento is very beneficial for the skin, especially in terms of moisturization. Don’t be surprised if you see many regular patrons of the sento who are upwards of eighty-years-old but still have fantastic skin. Bathing in sento also increases the efficacy of skin care products. I am a fan of organic skin care products and I find that they work even better thanks to the improved quality of my skin from the sento. 

Furthermore, bathing in a sento is a great way to warm up your body and stay healthy. I haven’t had a cold in the winter since I started bathing regularly at sento. Stretching in the bath (provided you don’t bump into other bathers!) is also highly recommended as your body limbers up quickly in the hot water. My stiff shoulders have greatly improved thanks to my bathing habits!

A sense of community
Why Japanese put towels on their heads in the sento or onsen
You'll often see Japanese people relaxing in the sento with a small, damp towel on their heads. This is to keep from overheating and having the blood rush to their heads. 

Sento can give you insight into what the local community is like. These places attract all sorts of people. There are bathers who bring their children for both quality time and the opportunity to teach them good manners. For the elderly, sento are essential for keeping people connected to each other. Young couples might enjoy a trip to a sento on a date while Japan’s suited “salarymen” might stop by to refresh and relax on their way home from work-- and to enjoy an icy cold beer after getting out of the bath! When I go traveling, I like to do some “intelligence gathering” at the local onsen! Because the regulars as well as the owners are local residents, they know the best places to go in the area. The information you get here will very likely come in handy.

About sento and art

Takara yu garden and engawa
The Japanese-style garden and engawa porch is a must-see point at Takara Yu located in Kitasenju, Adachi Ward.

While you may not think that sento and art would have much in common, sento actually have many artistic touches. First, there is the architecture of the building itself; many were built using the same traditional styles used for shrines. Then there are the works of art inside the bathing areas where you might see a beautiful painting of Mt. Fuji or an image created from mosaic tiles on the wall. There are also sento that have distinctly Japanese design elements such as an engawa or veranda attached to the dressing room or even a Japanese-style garden. Recently there are even so-called “designer sento” that use modern art forms such as projection mapping.

About murals in sento
Arai-yu mural

You can often see large murals painted on the walls of the bathing area of sento. These are commonly called penki-e (literally “paint picture”) in Japanese. One of the most popular subjects for these murals is Mt. Fuji. It’s said that these murals of Mt. Fuji first appeared in 1912 at a sento called Kikaiyu in Tokyo’s Kanda Sarugaku-cho area. It was supposedly painted for the amusement of children. Of course, there are now also many different subjects used for sento murals based on the request of the owner. 
Unsuisen penki e

There are currently only three painters in all of Japan who continue to paint this style of mural for sento. They are Mr. Kiyoto Maruyama (aged 81), Mr. Morio Nakajima (aged 71), and Ms. Mizuki Tanaka (aged 33).
