A property where you can enjoy creative kaiseki cuisine and pristine onsen at a traditional hearth.
I gave this as a Mother’s Day and Father’s Day gift for my parents. They were very pleased, saying they were satisfied with everything—the meals, service, Onsen, and Room—and that it was a wonderful Accommodation. The bus stop to the ropeway for Senjojiki Cirque is right in front of the Accommodation, and on our way home they noticed my father had forgotten his phone charger and staff kindly returned it to him. Thank you very much for your thoughtful hospitality. Thanks to you, my parents had a great trip, and I’m truly grateful.
Sea glass 6/2/2026We stayed during the cherry blossom season in full bloom. The view from the Room was absolutely stunning, and we were able to relax and enjoy a truly luxurious time. The food was also excellent—we thoroughly enjoyed the irori hearth-cooked cuisine and were impressed by how delicious the local ingredients were. The hospitality was wonderful as well, and we felt healed at this comfortable Accommodation. When we left something behind, we truly appreciated your thoughtful care. Thank you very much. We will definitely stay again!

Introduction of the Accommodation

Our concept is "Creating a property that embodies the charm of Shinshu and relaxation," and we strive diligently every day to achieve this. You can immerse yourself in the natural beauty of Mount Komagatake in the Central Alps and the rustic atmosphere, enjoying a relaxing and extraordinary space. Another aspect we take pride in is offering original cuisine made with local ingredients. Enjoy kaiseki meals around a traditional hearth and savor the nostalgia of the good old days.

From luxurious Rooms with hinoki baths to standard Japanese-style Rooms. We offer four distinct types of Rooms, preserving the essence of Japanese aesthetics. Relax your body in the Onsen and lie down on the tatami... Enjoy the luxurious moments unique to a Ryokan.

At our facility, we offer "Nii Nii's Onsen" and "Nee Nee's Onsen" sourced from the Sōtarō Onsen. After bathing, enjoy natural water from the melted snow of the Alps.

In modern times, the traditional irori hearth has become a rarity. At Yamaga-an Irorin-tei, you can enjoy the seasonal flavors of Shinshu Komagane, which change monthly, around the irori.
