Etymology

The name of Mount Yonaha in the Japanese language is formed from three kanji, 与, 那, and 覇. The kanji are ateji, or kanji used phonetically to represent native or borrowed words.

Geography

Mount Yonaha is located approximately 80 km (50 mi) north of the capital of Okinawa Prefecture, Naha,[2] and approximately 4.5 km (3 mi) east of the Okuma district (奥間集落, Okuma shūraku) of Kunigami. Mount Yonaha is formed from schist, phyllite, and sandstone, and dates from the Tertiary period to the mid-Mesozoic era.[3] Mount Yonaha appears to be a gentle slope, but its summit is surrounded by a series of complex valleys.[1] It is the highest mountain on the island and the second highest in the prefecture after Mount Omoto 525.5 m (1,724 ft) in Ishigaki, Okinawa.[3] Mount Yonaha is part of the Okinawa Kaigan Quasi-National Park, and is the highest mountain in the park. A paved mountain road extends from the village of Kunigami at the base of Mount Yonaha to the mountain summit.[3] Mount Yonaha is also home to the largest waterfall on Okinawa Island, the Hiji Waterfall (26 m (85 ft)).[2] Mounta Yonaha, due to the effect of the Kuroshio Current, is almost always covered in fog.[2]

Yanbaru forest

Mount Yonaha is at the center of the Yanbaru forest that spans the villages of Higashi, Kunigami, and Ōgimi. Yanbaru contains some of the last large surviving tracts of subtropical rainforest in Asia, and the mountain is lush with evergreens forests. While Mount Yonaha is an important natural habitat to numerous species of plants, birds, and animals, the ecology of the mountain has been negatively affected by agricultural development at the base of the mountain, and lumbering and the subsequent establishment of second-growth forest.[3]

Military installation

The summit of Mount Yonaha is approximately 2 km (1 mi) west of the border of Camp Gonsalves, a jungle warfare training center of the United States Marine Corps.
