Sanninudai & Gunkan-iwa
サンニヌ台
Sea-cliff viewpoint on the southeast coast of Yonaguni, where layered sandstone ledges and the sea stack “Gunkan-iwa” (Battleship Rock) form a dramatic coastline. The rock formations resemble underwater ruins.
Sanninudai is a cliff lookout on Yonaguni's southeast coast. Waves have carved the sandstone into successive terraces and steps that closely resemble underwater ruins, making it a good place to consider the “natural formation” theory. Below the viewpoint, a battleship-shaped rock stands in the sea, called “Gunkan-iwa” (Battleship Rock), and the scene is vast and wild. From the parking lot, the walk to the cliff edge takes about 10 minutes. Some rock ledges have no railings, so stay well back from the edge and avoid approaching it on windy days. Admission is free. It lies between Tachigami-iwa and Higashizaki.
