We sincerely hope you feel refreshed by soaking in a clean bathtub, as well as eagerly hope you get relaxed in fresh natural spring water.
To keep bath water clean, we thoroughly wash all the bathtubs clean every single day.

Remove all hot water from all bathtubs and thoroughly clean

First, after business hours we drain all bathtubs.
And then, we wash every corner and joint of the large bathrooms' floor tiles and every gap between the rocks, using a high-pressure jet cleaner, not brushing by hand.
Minerals of hot spring water easily are apt to stick on bathtub and floor. Unless these minerals are washed away after draining the bathtub, they can immediately crystallize.

After draining and cleaning, we dehydrate bathtubs to kill Legionella prenumophila. The following morning, we fill all the bathtubs with fresh spring water.
As for private baths, we drain, clean and dehydrate the bathtubs right after use. Just before the new guests use it, we fill it with fresh water and issue a token to run spring water into the bathtub.

Cooling hot water using only natural power

Hyotan Onsen's spring water is about 100℃. It is too hot to run into the bathrooms directly and use for bathing.
Adding cold water, however, to cool it down can add impurities and impair the merits of natural hot spring water instantly.
Therefore, we set up yumetake, cooling device made of bamboo, with which boiling water is cooled down to between 45 to 50℃. This system is used to control the spring water temperature, even for the large public bath.
Our experienced staff adjust the water temperature carefully to the circumstances: season, weather and time of day. They do not use any machinery.

It is the strong determination of Hyotan Onsen to enable you to experience the very best of fresh natural hot spring any time you visit.

Using natural hot spring water is making the most use of minerals contained in "the gift from the earth."

But at Hyotan Onsen, we hope you realize the good effects of the minerals in steam form hot spring , adding to just soaking in hot spring water.

Commitment to hot water

Hyotan Onsen originated from a hot spring which the founder dug for the compassion of his wife, Matsu, suffering from rheumatism.

“I want to ease her pain by bathing in onsen,” his consideration for her encouraged him to make a rock bath in a shape of a hyotan, which started everything about Hyotan Onsen.

The founder, Junsaku, traveled around Japan to gather materials, such as crooked logs and rocks, in order to make a hyotan-shaped bath and observatory. He respected Toyotomi Hideyoshi, a16th-century great samurai leader, who allegedly liked hyotan or gourd.

The founder’s omotenashi, hospitality made up of concern, consideration and sense of fun is still alive.
