If you’re a foreigner who lives in Japan or came to Japan as a tourist, many of you may have heard of Japanese sento, public baths. If you have been before what did you think? Don’t you agree it’s a convenient place to relax and heal yourself?

What are sento? Are you ready to know all about Japanese public baths?

Sento are public baths that can be enjoyed by paying customers. They are somewhat similar to onsen (hot springs) but onsen are heated naturally and sento are man-made.

Here in Japan, sento are very popular, and this article will show you the history and the reason why Japanese people love sento.

1. When did sento first appear in Japan?

Japanese people first created sento to make a living. A sento is a public bath where people can take a bath by paying an entrance fee, which we call “Bandai.”

It is said that sento were already popular among locals in the age of the Heian Period in Kyoto, according to the Japanese oldest collection of stories.
In the age of Edo Period (1603-1868), people enjoyed visiting sento daily.
By the year 1810, the total of sento businesses came to about 523!

There were two types of Sento at that time, which were:

1. Steam Bath Style
Enjoying hot steam, like a sauna
2. Soaking Bath Style
Enjoying a bath in hot water

Since people preferred the hot water soaking style, the steam bath style gradually declined.

2. From mixed bathing to gender-separate

In the Edo Period (1787-), there were both mixed bathing, and gender divided.
The mixed bathing style was more prevalent in Kansai than Edo at that time. For the sento managers, a mixed bath can save the cost since then there is no need to construct two types of rooms.

However, by the year of 1877 Meiji Period, western people criticized Japanese people for a mixed bathing style, so people stopped this bathing style and unified in creating separate baths for men and women.
The current style was created: gender-separate bathing rooms connected to the changing room.
Japanese people improved this to make a more relaxed Sento for everyone.

3. Do you prefer to bathe at home or the sento?

Even though Japanese people love Sento, sadly, sento numbers declined considerably due to the widespread of baths in regular homes.
Now, we have about 4,000 Sento in Japan, but it’s only a quarter of the number we had during the peak of Sento’s popularity.
However, Japanese people still enjoy the open relationships made with people from sharing sento together, even naked with strangers.

Owners continued to make efforts in improving sento to those with stylish designs, and this continuously attracts people even if they have a bath of their own at home.

4. The latest innovation for sento

What attracts people tosSento these days?
When they first started to appear, locals paid an entrance fee and simply took a bath; they were happy with the arrangement.

But now some features have been added to sento:

1. Open-air bath


The owners of sento needed to create something unique that people can’t usually experience at home to continue bringing customers back.
So Japanese people made an open-air bath and sauna at Sento. By bathing in the open air, you can feel as though you’re taking a dip in an onsen (hot spring), and you can sweat in the sauna. These additional new features attract Japanese people a considerable amount.

2. Sauna

What’s so good about saunas?

1. It improves blood flow and helps reduce shoulder pain.
2. It promotes recovery from exhaustion by sweating the substances produced by fatigue from your body.
3. It eliminates your stress by improving stable nerve function and helps recovery from insomnia.

2.  Nothing is as good as drinking beer after taking a bath


At most recent sento, you can drink beer, coffee-flavored milk, and soft drinks after taking a bath.
There are usually vending machines right outside selling these drinks.
If you go to Sento by car, of course, you can’t drink alcohol. If it’s by train or walking, however, you can enjoy the taste and feeling of having a beer and feeling refreshed as well.
