Visit Mastumoto

Nestled within a birch forest just beyond the hot spring town, this secluded hot spring inn stands in tranquil solitude. Perched deep in the mountains at over 1,400 meters above sea level, it offers an escape from the clamor of daily life, allowing you to feel the breath of nature with your entire being.Soak in the hot springs while gazing at

the birch forest, which reveals its changing seasonal beauty. This renowned hot spring is said to prevent colds for three years if you bathe for three days. Enjoy the gently sulfur-scented, free-flowing spring water in the indoor bath and in one of the few free private open-air baths available at Shirahone Onsen.The semi-open-air bath features layers of calcite, crystallized from the spring's minerals, offering a close-up view of nature's artistry.

Our cuisine features kaiseki-style dishes using Shinshu's seasonal ingredients. We take pride in creative dishes utilizing the drinkable spring water, such as hot spring shabu-shabu featuring Shinshu beef and pork, and hot spring rice porridge. Spend peaceful moments in detached cottages or special rooms, relocated from old Edo-period houses.
