Ito Onsen is regarded as one of Japan's top three hot spring destinations, alongside Beppu Onsen in Ōita Prefecture and Yufuin Onsen in Ōita Prefecture. It is also renowned as one of the leading Onsen resorts in Japan, particularly famous for having the largest volume of hot spring water in Shizuoka Prefecture At Ito Kowakien, we offer a unique amenity in Ito City - drinkable hot spring water available at our 'Insen-dokoro' service station.

5 Kyes to Thoroughly Enjoy Ito Onsen A Well-Known Hot Spring5 Points

#1
Enjoy the Historical Ito Hot Spring to the Fullest

The hot spring of Ito Kowakien is pH 8.4, slightly alkaline simple hot spring. The alkaline water is effective to remove the dirt and the old skin cells from the skin due to its high perspiration effect and known as a “skin conditioning hot spring”. Relaxing in our natural hot spring water bath, you can relieve daily stress and experience effects to get fit. In our open-air bath, you can feel totally refreshed physically and mentally by feeling the essence of every season in the middle of natural wind.

#2
In the large bathroom, the alternate bathing of “very hot bath” and “warm bath” is a must-try recommendation.

We have a large bathroom and an open-air bath for each gender, which switch at 2:00 a.m. so that you can enjoy the different baths on your check-in day and the following morning.
In both bathrooms, we have a “very hot bath” and “warm bath” that you can choose one you feel comfortable with or you can try the alternate bathing to improve your metabolism. Children usually don’t like very hot water for bathing, but in Ito Kowakien, we have a “warm bath” where all the children can enjoy with their parent without any worry.

【Very hot bath】
The setting temperature of this bath is 42℃, which is known as a temperature with an effect to give you “energy” by stimulating your sympathetic nerve and giving tension and stimulation to your body.

【Warm bath】
The setting temperature of this bath is from 39 to 40℃, which can give you a “relaxation” effect by stimulating your parasympathetic nerve system to calm your mind down.
For your information, in Ito Kowakien, we drain the water from the bathtubs and pour the new hot spring water every day, which allows you to enjoy very fresh “direct supply hot spring” every day.
