Zao Onsen (蔵王温泉) is a popular hot spring resort located in the northeastern part of Yamagata and Miyagi prefectures, Japan. It is situated at the foot of Mount Zao, an active volcano that has a beautiful natural landscape and is known for its famous “snow monsters” or “juhyo” that form during the winter season.
The hot springs in Zao Onsen are known for their healing properties and have been a popular destination for travelers for centuries. The area boasts various types of hot springs, including sulfur, acid, simple, and hydrogen carbonate springs. There are many traditional Japanese inns or “ryokans,” as well as hotels, that offer hot spring baths, traditional Japanese meals, and a relaxing atmosphere for visitors.
In addition to the hot springs, there are many outdoor activities to enjoy in Zao Onsen, including skiing and snowboarding during the winter season and hiking and nature walks during the warmer months. The Zao Ropeway, a cable car that takes visitors up to the peak of Mount Zao, offers stunning views of the surrounding landscape and is a popular attraction year-round.
