Guide
Itashiro Onsen is located at the western edge of the Nasu mountain range, near the headwaters of the Nakagawa River in Nasushiobara City, Tochigi Prefecture. With a history spanning over 1,000 years, it has long been celebrated as the 'Medicinal Hot Spring of Shimotsuke.' In 1971, it was designated as a National Wellness Resort and continues to be a premier destination for relaxation and rejuvenation. Situated within the scenic Nikko National Park, the area offers not only soothing hot springs but also a variety of activities that leverage the breathtaking natural environment.
The history of this region dates back to the Heian period (1059). It is said that the local lord of Nasu, Nasu Muneshige, discovered the hot springs while hunting. Following this discovery, the local people of Itashiro began operating inns, establishing the area as a formal hot spring destination. During the early modern period, it became one of the famous 'Seven Hot Springs of Nasu,' attracting many visitors seeking medicinal healing. The area is even nicknamed the 'Spring of No Need for a Cane,' referring to the tradition where people left their walking sticks behind after their health was restored by the waters. This profound heritage continues to preserve the traditional 'Toji' (hot spring healing) culture today.
Itashiro Onsen is home to several unique cultural and natural landmarks. A standout feature is the 'Tsuna-no-yu' (Rope Bathing). This traditional method involves holding onto a rope tied to the beams of a bathhouse while soaking in water deeper than the waist, utilizing water pressure for a unique therapeutic experience. The area also features sacred sites such as Itashiro Onsen Shrine, Kamo Iwafuji Shrine, and Kinomata Jizo, where visitors have long prayed for healing. For nature lovers, the area offers stunning views of Otome Falls and the Numappara Wetlands, where you can experience the rich biodiversity of Nikko National Park up close.
Itashiro Onsen reveals a different face in every season. From May to October, it is an ideal time for trekking through the Numappara Wetlands to observe alpine plants like Nikko Kisuge (daylilies) and Eriocaon. During the summer, the riverbanks near Otome Falls are popular spots for cooling off. In winter, the area is often covered in snow, making it a perfect time for a peaceful retreat in a warm hot spring. Additionally, the annual 'Itashiro Onsen Dondo-yaki' festival held in January offers a wonderful opportunity to experience deep-rooted local traditions.
Beyond soaking in the hot springs, the surrounding area serves as an expansive field for outdoor-based activities. It is a popular base for mountaineering toward the Nasu mountains and offers various trekking routes. In the Numappara Wetlands, well-maintained boardwalks allow for easy observation of alpine flora and local wildlife. Furthermore, the area is embracing modern trends like 'Modern Toji Workations,' inviting travelers to combine remote work with the healing power of the hot springs for a new way of living and working.
The area surrounding the hot spring town is rich with natural attractions. Otome Falls is a favorite spot for visitors to enjoy the refreshing atmosphere in the summer. Nearby, the Miyama Dam and its reservoir offer scenic views of the rugged, mountainous landscape. The Numappara Wetlands also serves as a vital starting point for trekkers heading toward the Nasu mountain range, acting as a hub for nature observation and exploration.
