ABOUT

About this spot

At an elevation of about 1,800 m, where you can sometimes look down on the clouds, Manza Onsen is one of Japan's finest alpine hot spring resorts, known as the "hot spring closest to the stars." Its greatest feature is a sulfur content said to be the richest in Japan. The milky-white spring water is highly effective for beautifying skin and detoxing, and has long been loved as a place for therapeutic bathing. The area is also rich in seasonal expressions: refreshing highland breezes in summer, autumn leaves coloring the mountains in fall, and in winter, snow-viewing baths in a world of white, offering a luxurious experience unique to this place. In particular, from the open-air baths with their sense of openness, you can gaze up at a night sky overflowing with stars, an overwhelmingly beautiful sight. It is ideal for solo trips and girls' trips seeking to reset mind and body in quiet, and with ski resorts adjacent, also for families and groups of friends enjoying winter sports. Why not spend a special holiday far from the bustle of daily life, wrapped in magnificent nature and superb hot springs?
