Nakayamadaira Onsen (中山平温泉): The Serene “Eel Water” Sanctuary
Among the 5 onsen towns in Naruko Onsen area, Nakayamadaira Onsen stands out as the most serene and “untouched” corner. The town is famously known as the home of Unagi-yu (Eel Water). Unlike more developed resort towns, it retains a quiet, rustic atmosphere where the focus remains entirely on the raw quality of the earth’s gift. Its waters are legendary for their high alkalinity and syrupy, “torotoro” texture, which acts as a natural beauty serum, enveloping the skin in a silky veil that leaves it remarkably smooth long after you have dried off.
What makes the town truly special is how it harmonizes this therapeutic water with the dramatic cycles of the Japanese seasons. It serves as the quiet gateway to the Naruko Gorge, allowing travelers to retreat from the busy autumn crowds into a landscape of vibrant crimsons and silent winter snowscapes. Whether you are soaking in 100% pure volcanic minerals at a local public bath or watching the steam rise against a backdrop of ancient mountains, Nakayamadaira offers a pure, unhurried experience for those who wish to heal both body and soul in the heart of nature.

Musubiya (むすびや): Rice Balls Made With Love Using Rice From Naruko
Situated just a two-minute drive from the iconic Naruko Gorge, Musubiya is an essential stop for travelers looking to experience the region’s agricultural heritage. The shop is housed in a traditional, lone-standing building that overlooks the peaceful satoyama (rural landscape), serving as the primary showcase for the Naruko Rice Project (鳴子の米プロジェクト). Founded in 2006 to revitalize local farming, this project developed the premium Yuki-musubi (ゆきむすび) rice variety specifically to thrive in Naruko’s cool climate. Today, the shop is a community hub where local women hand-press onigiri to order, offering a direct taste of the area’s resilience and culinary innovation.
Every ingredient is sourced through personal relationships with local producers to ensure the highest quality. While the shop has shifted primarily to takeout and bento boxes, the experience remains artisanal. Each onigiri is shaped only after you order, arriving warm and substantial in size.
The store also sells locally grown vegetables that are pesticide-free and chemical-fertilizer-free.
Yuki-musubi: Delicious Rice Even When Cold
The shop’s signature is its 100% Yuki-musubi rice. Categorized as a “low-amylose” grain, it sits texturally between standard white rice and sticky mochi rice. This gives it a distinctively chewy, sweet profile and a rare ability to stay soft and flavorful even when cold, a trait that has made it a favorite among rice connoisseurs across Japan.
The Menu at Musubiya
Musubiya’s menu features seven permanent staples along with rotating seasonal and weekend specials.
- The Fan Favorite: Kōi Nanban Miso (麹なんばん味噌): A perfect harmony of spicy fermented koji and savory miso that balances the natural sweetness of the rice.
