Nasu Onsen-go — relief & relaxation | Compare & book inns

Overview

Nasu Onsen-go is a collective term for the hot spring resorts scattered at the foot of Mt. Nasu in northern Tochigi Prefecture. Its history dates back approximately 1,390 years to 630 AD. Legend has it that a hunter, tracking a wounded deer deep into the mountains, discovered the animal healing its wounds in a hot spring. He named it "Shika-no-yu" (Deer's Spring), marking the origin of Nasu Onsen.

The area was visited by the famous poet Matsuo Basho in the Edo period and developed into one of Japan's premier highland resorts after an Imperial Villa was established here in the Meiji era. Once known as the "Nasu Seven Springs," many more sources have since been discovered, each offering hot springs with different mineral qualities and atmospheres. The great appeal of Nasu is the opportunity to enjoy bathing amid beautiful, changing scenery throughout the four seasons.

Key Spring Types and Health Benefits

Nasu is famous for its cloudy, white sulfur springs, typified by the iconic Shika-no-yu. These waters are said to have high sterilizing effects and may be beneficial for the skin. The area also boasts a variety of other spring types, including simple thermal and acidic springs, allowing visitors to experience a range of therapeutic effects by 'onsen-hopping'.

Water Characteristics and Best Season to Visit

Shika-no-yu features several baths with temperatures ranging from a hot 41°C to 48°C. A traditional bathing method involves first soaking up to your waist (hanshin-yoku), then repeatedly pouring hot water over your head with a ladle (kaburi-yu) about 200 times before fully immersing your body. Many facilities offer free-flowing spring water straight from the source.

The Nasu Highlands are a charming resort destination throughout the year: fresh green in spring, a cool retreat in summer, autumn foliage, and snow-viewing baths in winter. The area is particularly popular from early to mid-October when the autumn colors on Mt. Nasu are at their peak, drawing many tourists for the stunning views and hot springs.
