Below, we delve into the history and meaning of bandai, tomeoke, okayu, sansuke, zakuroguchi, nakabukuro, tenugui, furoshiki.

What Is Sento Nukabukuro

Nukabukuro (f) is a body scrubbing tool, with a similar purpose of a today’s loofah sponge. It is really a ‘bukuro‘ or a bag filled with rice bran and it has exfoliating properties. In the past it was mostly used by women in the sento. Nukabukuro are being sold even today, of course with some new designs.


What Is Sento Sansuke

Sansuke (d) is a male bathhouse assistant to both male and female customers in charge of preparing buckets of rinsing water, scrubbing customers’ backs and taking care of the waiting list. 

Sansuke replaced ‘yuna’ girls who originally had this job, but after some time they also started giving sexual services. The inappropriate act of having sex in a Japanese bath prompted the authorities to ban them. 

Sansuke were paid well and had a high position in the sento. Previously they had to go through responsibilities such as maintaining bath temperature. Today there are no sansuke in the sento

What Is Sento Tenugui

Tenugui is a narrow and long Japanese cotton cloth mainly used as a towel, washcloth, or dishcloth, It can also be used as a decoration, as wrapping, and a headband. Tenugui always have some kind of design or pattern and new designs keep coming out. Often designs feature pop culture elements. Recently, there has been a revival of buying and selling tenugui, as they also make very good souvenirs and gifts.


What Is Sento Zakurochi

Zakuroguchi (e), meaning “pomegranate entrance”, is an entrance to the bath area at a typical Edo style sento. Actually, what many Japanese people know as sento today is slightly different from traditional sento in the Meiji period. 

This entrance was very low in order to leave the least open space possible. This was to keep the heat steam from escaping. 

In the Meiji period the bath became open, the walls and ceilings became high and there were even windows to let the steam escape. As a result, the zakuroguchi disappeared.

What Is Sento Tomeoke

Tomeoke (b) can have two meanings. Firstly a private oval oke bucket that you use to pour water on yourself in the sento. That water is for rinsing yourself after scrubbing your body.

Secondly, in the past, oke were buckets that richer families would pay extra money to keep them for their private use.

What Is Sento Okayu

Okayu (c) is the clean water used to rinse yourself after scrubbing, scooped up by the oke bucket. This was the last step before you could enter the sento bath.


What Is Sento Bandai

Bandai (a) is the space dividing the male and female bath. A person would overlook the male and female bath area from a high chair in between. This person also works as a receptionist and cashier. In the past all sentos had a bandai person. However, now it has been replaced by a simple reception desk at the entrance of the sentos. Even today, small sentos with a bandai person remain, although they’re extremely rare.

What is Sento Furoshiki

Furoshiki (h) is versatile cloth that can transform into many things. It has been a convenient item in the life of every Japanese person since the Nara period. It has several sizes, ranging from small to extra large. In addition, it can be made of various fabrics like silk, cotton, and polyester. 

Depending on how you tie it, it can become a great gift wrap, a sturdy bag, a backpack, a bento bag, or a bottle carrier. You can even transport a whole watermelon in a neatly tied furoshiki! But the ‘furo’ in ‘furoshiki’ stuck because one of its uses is carrying all your bathing supplies. Furoshiki have many designs. In fact, you can even wear them as accessories or use them as decoration. 

Because it is reusable and renders plastic bags unnecessary, this magical, shape-shifting cloth is also eco-friendly
