Overview
Zao Onsen is one of Japan's oldest hot spring areas, said to have been discovered in 110 AD. Situated at an altitude of 880 meters, it has long flourished as a therapeutic spa destination.
Its most prominent feature is the "Juhyo" (Snow Monsters) seen in winter. This natural art, created by the unique weather conditions of the Zao mountain range, attracts tourists from all over the world. The onsen town has also developed into a major ski resort, making it a mountain retreat enjoyable throughout the year.
Spring Quality and Indications
The water at Zao Onsen is a strongly acidic sulfur spring, one of the most potent in Japan. Characterized by its milky-white appearance and distinct sulfur aroma, its high bactericidal effect helps to smooth the skin, earning it the nicknames "Princess's Spring" and "Spring of Beauty."

Water Characteristics and Best Season
The source temperature is high, ranging from 45-66°C (113-151°F), with an abundant flow. Many facilities offer free-flowing hot spring baths directly from the source. Due to its strong acidity, it can tarnish precious metals, and individuals with sensitive skin should be mindful of over-bathing.
Winter (December to February) is the best season for skiing and viewing the Snow Monsters. From summer to autumn (June to October), visitors can enjoy hiking amidst fresh greenery or autumn foliage and see the emerald-green Okama Crater Lake.
