Nasu Onsen
10 min di letturaOverview & Charm
Nasu Onsen is a collection of charming hot spring areas located around Nasu Town in Nasu District, Tochig, at the southern foot of Mt. Nasu within Nikko National Park. With a history dating back centuries, the area is famous for the "Nasu Twelve Springs" and "Nasu Seven Springs," each offering unique mineral compositions and distinct atmospheres. From historic public baths to secluded mountain retreats and retro-style inns, every visit offers a new discovery. Immerse yourself in a luxurious time of deep relaxation amidst breathtaking natural scenery.
History & Cultural Background
The history of Nasu Onsen is incredibly ancient. According to legend, the hot springs were discovered in 630 AD (the Asuka period) when a man named Kano Saburo Yukihiro observed a deer healing its wounds in the thermal waters. During the Edo period, the area was managed by the Kurobane Clan, and the famous poet Matsuo Basho recorded staying in this land during his travels in "Oku no Hosomichi." The area also holds prestige as a high-class medicinal bath site; for instance, the military leader Nogi Maresuke and his wife visited during the Meiji era. Many local inns still display photos and decorations from the pre-war era, allowing visitors to feel the cultural depth of Japan's modern history.

Main Attractions
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 where you can enjoy unique sulfurous hydrogen springs. Another famous spot is "Kita Onsen," known as a filming location for the movie 'Thermae Romae.' It is characterized by its large outdoor bath called the "Oyogi-ba" and a unique atmosphere adorned with Tengu masks. Additionally, you can experience different environments such as the high-altitude "Daimaru Onsen" or the extremely secluded "Mitsutogoya Onsen," which is only accessible by hiking.
Seasonal Recommendations
Nasu Onsen offers different faces throughout the seasons, but the best times to visit are during the fresh greenery of spring and the vibrant foliage of autumn. Enjoying a soak while watching the seasonal changes of the lush Nikko National Park—such as the blooming azaleas near Hachiman Onsen—is a special experience. In winter, the outdoor baths amidst a snowy landscape create a magical, dreamlike atmosphere. We recommend strolling through the hot spring streets during the day and soaking in the silence of the springs at night to achieve deep relaxation.

Experiences & Activities
The true essence of Nasu Onsen is the "Yunomeguri" (hot spring hopping). By visiting different facilities, you can experience various mineral-rich waters such as simple springs, iron springs, or sulfate-hydrogen sulfide springs, each providing different physical sensations. Staying in a retro building like those in Kita Onsen feels like stepping back into the Showa era. For those seeking absolute solitude, the mountain-hidden Mitsutogoya Onsen offers a chance to escape the noise of modern life entirely.
Surrounding Areas
As part of Nikko National Park, the area is surrounded by many attractions. Nearby, you can visit the area of the "Sessho-seki" (Killing Stone) and the legends 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, making it easy to combine your hot spring stay with hiking and nature observation. The hot spring village serves as a perfect base for a journey combining nature and history.
