Guide
Nasu Onsen is a collection of charming hot spring villages located around Nasu Town, Nasu District, at the southern foot of Mt. Nasu within Nikko National Park. With a history spanning centuries, the area is famous for the "Nasu Twelve Springs" and "Nasi Seven Springs," each offering unique mineral properties and distinct atmospheres. Whether you are visiting traditional public baths, secluded mountain springs, or nostalgic inns, every visit offers a new discovery. The combination of rich natural scenery and therapeutic waters provides a deeply relaxing experience for both body and mind.
The history of Nasu Onsen is incredibly ancient. According to legend, the hot spring was discovered in 630 AD (the Asuka period) when a hunter named Saburo Kano observed a deer healing its wounds in the hot water. During the Edo period, the area was managed by the Kurobane Clan, and the famous poet Matsuo Basho is recorded to have stayed here during his travels in "Oku no Hosomichi." The area also holds a high-class reputation; for instance, the military leader Nogi Maresuke and his wife visited the area. Some local inns even display historical photographs and medals from the pre-war era, offering a glimpse into Japan's modern history.
The Nasu Onsen area consists of several distinct hot spring zones. The most historic, Nasu Yumoto Onsen, features the iconic Shika-no-yu, a public bath known for its unique hydrogen sulfide spring water. Kita Onsen is another highlight, famous as a filming location for the movie "Thermae Romae," featuring a massive outdoor bath called "Oyogi-ba" and a nostalgic atmosphere decorated with traditional masks. Other notable spots include the high-altitude Daimaru Onsen and the secluded Toppokoya Onsen, which can only be reached by hiking, offering a truly remote and tranquil experience.
Nasu Onsen reveals a different face in every season. The area is particularly stunning during the seasons of fresh greenery in spring and vibrant autumn foliage. Bathing while overlooking the changing colors of the Nikko National Park landscape is a sublime experience. In winter, the outdoor baths (rotenburo) create a magical, dreamlike atmosphere amidst the falling snow. We recommend enjoying a stroll through the hot spring streets during the day and soaking in the quietude of the springs at night to achieve deep relaxation.
The true essence of Nasu Onsen lies in "Yunomeguri" (hot spring hopping). You can experience different physical sensations by visiting facilities with various water types, such as simple springs, iron-rich springs, or sulfate-hydrogen sulfide springs. Staying at a retro-style inn like those in Kita Onsen feels like stepping back into the Showa era. For those seeking total isolation from modern life, the mountain springs like Toppokoya Onsen offer a profound sense of silence and peace.
As part of Nikko National Park, the area is surrounded by many attractions. Nearby, you can visit the mysterious Sesso-ishi (Killing Stone) area, tied to the legend of the Nine-Tailed Fox, or explore sites related to the Imperial Family, such as the Nasu Imperial Villa. The Nasu Ropeway also provides easy access to Mt. Chausu for hiking and nature observation, making it easy to combine a hot spring retreat with outdoor adventures.
