Sanbe Onsen

Springing up at the southern foot of Mount Sanbe in Ota City, Sanbe Onsen is a highland spa cradled in grand nature. It boasts abundant water, and its iron and mineral rich supply turns reddish brown when it meets the air. The clear air of the elevated setting and the ever changing views of Mount Sanbe bring visitors an open, refreshing time.

Highlights

The spring water is clear as it emerges from the source, but the iron content turns it reddish brown on contact with the air. It has long been favored by healing bathers as a spring that warms deeply. Nearby lie trails up Mount Sanbe, campgrounds, and a nature park, and many people pair a hike or nature watching with a soak. The area is also known as the place where an ancient buried forest was discovered.

Enjoying the Seasons

In spring, fresh greenery buds on the mountainside and crisp breezes sweep the highland. Summer makes it a popular retreat from the heat, and a bath in the cool uplands is a special pleasure. Autumn brings splendid foliage on Mount Sanbe, and bath hopping while gazing at the coloring slopes is a joy. In winter, the contrast of the snow covered mountain and the deeply warming water is striking, offering a quiet snow viewing bath.

Access and Basic Information

The onsen sits in Shigaku, Sanbe, Ota City. It lies inland from Odashi Station on the JR Sanin Main Line, reachable by car or bus. Convenient as a base for touring Mount Sanbe, it is surrounded by lodgings and places for nature activities. Some facilities accept day visitors, and many stop by while hiking or driving.

A Quick Tip

Since the reddish brown water can stain towels, it is safer to avoid white ones. Because the highland sees a wide gap between day and night temperatures, bringing an extra layer keeps you comfortable. Enjoy both the grand nature of Mount Sanbe and the warming, celebrated water together.
