Best Private Hot Springs Across Japan
For me, one of the most relaxing and unforgettable experiences in Japan has always been soaking in an onsen. But while traditional hot springs are usually shared, there’s something extra special about having one all to yourself. A private onsen lets you enjoy the soothing mineral-rich waters in total peace — whether it’s a bath attached to your ryokan room, a secluded outdoor tub overlooking mountains or the sea, or a hidden retreat deep in nature. These private hot springs are perfect for couples, families, or anyone who wants the full onsen experience with comfort and privacy. From Hakone’s luxury ryokans to Hokkaido’s snowy retreats and seaside baths in Izu, here are some of the best private hot springs in Japan that combine relaxation, stunning scenery, and a touch of traditional Japanese hospitality.
Onsen Sanso Daikon no Hana (Miyagi)
One of the highlights of staying at Onsen Sansō Daikon no Hana is the chance to soak in your very own private hot spring bath. Some guest rooms come with open-air rotenburo, where you can slip into steaming mineral water while gazing out at the forest — cherry blossoms in spring, lush greenery in summer, fiery leaves in autumn, or soft blankets of snow in winter. The ryokan’s waters come not only from the famous Tōgatta Onsen but also from its own natural hot spring source, ensuring an abundant flow of healing, mineral-rich water. With the sound of rustling leaves and the scent of the seasons around you, bathing here feels deeply personal and restorative, like nature itself is wrapping you in warmth.

Bettei Senjyuan (Minakami, Gunma)
At Bettei Senjyuan, every guest room comes with its own private open-air hot spring bath, making it one of the most exclusive onsen experiences in Japan. Surrounded by the dramatic mountains of Minakami and the clear waters of the Tone River, the baths are perfectly positioned to let you enjoy the changing beauty of the seasons — cherry blossoms in spring, lush greenery in summer, fiery foliage in autumn, and a snowy wonderland in winter. The water is drawn directly from a natural source, rich in minerals that soothe both body and mind. Soaking here, with nothing but the sound of the river and the sight of the mountains around you, feels like a private retreat into nature itself — a moment of pure luxury and serenity.
