Nagano Prefecture/KawanakajimaRelax and rejuvenate at the Onsen associated with Takeda Shingen, and enjoy unique baths.
Suburbs of Nagano City. A traditional Japanese-style Onsen Ryokan surrounded by greenery. Located at the foot of Mount Chausu, where Shingen Takeda built a castle during the Battle of Kawanakajima, this area is home to Nakaoyama Onsen, historically known as a healing spot for Takeda's warriors. We own the hot spring source, allowing you to enjoy 100% natural spring water. Famous for its unique baths, such as the "Omiai Bath," a distinctive open-air bath with a shrine at its boundary, and private karaoke baths. With excellent access to Nagano City's tourist attractions like Zenkoji Temple, it is a convenient base for your stay. Please visit this nostalgic and healing space.

Introduction of the Accommodation

The renowned Onsen Nakaozan, where even Sengoku warlords relaxed.
Located near the historic Kawanakajima battlefield, where Takeda Shingen and Uesugi Kenshin fought, it is said that the Takeda army healed their wounds at Nakaoyama Onsen. While the Onsen boasts a long history, the Onsen Facility officially opened in 1933 (Showa 8) and has been cherished as a therapeutic bath. The spring quality is a simple sulfur cold mineral spring, which warms the body to the core and provides excellent health benefits. It is also highly praised for its skin-smoothing properties, offering outstanding beauty effects. Guests can enjoy a variety of baths, including an open-air bath, a large public bath, a waterfall bath, a jacuzzi bath, and a low-temperature far-infrared sauna.

Enjoy seasonal flavors throughout the year.
Our head chef, having completed training in Kyoto, prepares dishes with a creative touch using seasonal ingredients. Therefore, the menu changes with the seasons.
