Mount Yonaha (与那覇岳) is the highest mountain on Okinawa Island, located in Okinawa Prefecture and notable for its subtropical forest environment. It serves as the island’s principal high point and is an established destination for local hikers and naturalists.

Trails through humid, biodiverse forest lead toward the summit area; hiking is typically non-technical and can be completed as a day trip. The mountain supports subtropical flora and fauna distinct from Japan’s temperate mainland ranges.

The peak is a natural highland feature rather than a constructed site; it has long-standing local significance as the island’s summit and is managed for conservation and recreational use. There are no major historical constructions on the summit.

Geographically it sits on Okinawa Island amid rolling forested hills and karst-influenced terrain, forming the island’s highest ground and reachable from nearby coastal towns by road and short inland approaches.
