An 11-room culinary Ryokan, founded as “Unagiya,” featuring guest rooms with private Onsen baths, a time-honored secret family recipe, and a refined Japanese-modern space.
Located about a 5-minute taxi ride from JR Tendo Station, "Tendoso" has been in operation for over 100 years since its founding as an eel restaurant in the early Meiji era. This small-scale accommodation features only 11 rooms, focusing on providing personalized hospitality to each guest. All guest rooms offer the enjoyment of Onsen. The property includes unique spaces such as "Rijin-kyo," a detached single-story building with traditional Sukiya-style architecture, and "Azumatei," a suite blending modern functionality with the aesthetic charm of Japanese-Western design. At Tendoso, it’s not just about relieving travel fatigue but also cherishing the joy of doing nothing. Spend blissful moments in a space where tradition and sophistication come alive, allowing your heart to unwind completely.
From the beautifully maintained greenery at the entrance, we immediately felt a wonderful atmosphere and looked forward to our stay. Just as expected, the hospitality, cuisine, Onsen, and Room were all excellent. The meals were beautifully presented with lovely tableware and staging, and the dishes made with many local ingredients were truly delicious. We also appreciated the complimentary sake for my birthday. The attendant who took care of us was kind and warm-hearted, which made us feel very comfortable. This stay reminded us once again how wonderful Yamagata Prefecture is.
ぶーるぶらん 9/5/2026I couldn’t forget how wonderful the food was, so this was our second visit.Both dinner and breakfast were outstanding and exceeded our expectations—we truly had a blissful time.Even vegetables I usually avoid were so delicious that I found myself thinking, “I didn’t know they could taste like this.”And of course, the eel was exceptional!!We also have a family member with limited mobility, and thanks to the minimal steps in the Room, as well as the handrails at the open-air bath in the guest room and even a bath chair provided for us, we were able to stay very comfortably.We sincerely appreciate your thoughtful attention to detail.We would love to visit again in another season!

Each bite quietly evokes the seasonal scenery around you.
