This is the highest mountain among the Amami Islands with an elevation of 694.4 meters (2278.21 ft.) above sea level. The mountain has a monument illustrating a legend that tells of two founding gods of the islands that came down from the heavenly sky to this mountain. This valuable mountain has a rich subtropical broad-leaved forest that houses a number of rare animals designated for special protection, including Amami Rabbit, Ryukyu Robin, Ryukyu Spiny Rat, Ryukyu long-tailed giant rat, and Lidth's jay. The area around the peak was designated as a quasi-national park special protection area in 1974. Visitors can access the observatory part at Mt. Yuwan by car, from which a great panoramic view of Yakeuchi Bay can be observed. The peak of the mountain can be reached on foot from the observatory park.
