Located in the middle of Hanamaki Minami Onsenkyo, Yama no Kami Onsen is named after the "Yamatsumi Shrine" that enshrines the mountain deity in this area. Yukaen, a Yama no Kami Onsen inn crafted by shrine carpenters, features lattice-patterned ceilings and intricate craftsmanship throughout the building, allowing you to fully enjoy a relaxing time surrounded by the warmth of wood.

A keyaki-wood Onsen Ryokan—beloved by Kenji Miyazawa and Torahiko Tamiya—crafted entirely from zelkova, a style that can no longer be recreated today. The historic Namari Onsen, first opened around 600 years ago, offers exceptionally high-quality waters recognized by selections such as “New Japan’s 100 Famous Hot Springs,” “Japan’s 100 Famous Hot Springs,” and “Japan’s Onsen Heritage.” Unusually even among well-known hot spring areas, the property has five source springs, and all four baths on site are luxurious 100% free-flowing natural spring water (kakenagashi). It is also known as “Namari-no-Yu,” featured in Kenji Miyazawa’s masterpiece *The Bears of Nametoko Mountain*, making this a special Accommodation where the story’s world and a historic Onsen come together. In 2025, the main building—of outstanding historical value—was designated a National Registered Tangible Cultural Property, allowing you to fully enjoy the beauty of traditional Japanese architecture as well. In particular, we highly recommend the 100% natural self-springing rock bath “Hakuen-no-Yu,” said to be Japan’s deepest—a superb bath that warms you through to your core.
