Want to try “Hako-mushi-buro (box steam bath) ?

箱蒸し風呂 熊本 泉屋

If you like Japanese hot springs called “onsen” and sauna, you really have to try the “box steam bath” called Hako-Mushi-buro.

It is great to get silky skin by sweating a lot of “good” sweat.

Even if you are not good with sauna, it is much easier to sit and wait till you sweat. You can breathe fresh air because your head is not in a “box steam” like a sauna.

Here’s what I experienced for the first time. Even Japanese, not so many people know about this kind of hot springs.

What is Hako Mushi Buro (box steam bath)?


Hako Mushi Buro is literally just a person who is in a box gets steamed like hot steamed vegetables.

The box is placed on the place where hot steam from hot springs comes out, so the steam goes into the box and get a person steamed. The top of the box has doors so you do not need to put your head in the box.

It is like a “personal sauna without a head”.


From the bottom of the box, the steam comes in. I’ve traveled all of the prefectures in Western Japan, but I have never seen this type of hot springs before.

I have tried mist sauna, and it was tiring, but since I can put my head out of the box, it was easy to stay in the box. It is like an open-air bath (“Roten buro”).

This steam bath can get your whole body nice natural steam, and your pores can absorb the hot springs great effects. It is said that this Hako Mushi Buro (steam box bath) is good for your skin and health, so people used to use this steam box bath when they had a cold.

What a good system!

Of course I can’t show what is inside like, but without a person, it is like this below.


You just pour the hot water from the hot spring and sit on this chair. Then you close the both doors.

Then gradually, the steam comes from the bottom, and you can feel “you are being steamed!”

It is hilarious to see a person whose head is only seen, trust me.

But after all, I really liked it! Being in a sauna without my head is so easy.

At this hotel, this box steam is available only on the certain days because they rotate this hot spring with another one which was for men on the day I visited day by day.

The other one is like a cave, and in this steam bath, you have to get your whole body in the “steam cave”.

There’s also another steam where you can lie and enjoy steam

If you visit Tsuetate Onsen, make sure you visit Izumiya

If the hot spring contains some bad chemicals, they can’t have this steam bath thing. So this is kind of Tsuetate Onsen exclusive onsen.

If you are interested in beauty, or you like sauna, or just looking for somewhere to relax, you definately should visit there.

This special hot spring is available for 500 yen, while the hot springs in the city costs like doubled and are inferior quality.

Izumiya is Ryokan(Japanese style hotel), so you can stay there
