Sonaichizaki, Desert island in Yonaguni, Japan.
Sonaichizaki is an uninhabited island that extends from the Yaeyama Islands chain, featuring natural rock formations along its untouched shoreline. The island displays the rough, unaltered landscape typical of many smaller islands in this southwestern Japanese region.
This island is part of Japan's extensive network of smaller islands and has remained largely unchanged for centuries. It retained its role as a geographic point in the maritime waters of the Yaeyama region, though it was never permanently settled.
Sonaichizaki maintains its original Japanese name 祖納地崎, reflecting the geographical naming traditions of the Yaeyama archipelago in the East China Sea.
Access requires careful planning and coordination with local boat operators from the main Yonaguni settlement, as no facilities exist on the island. Visitors should expect rough weather conditions and limited access depending on the season and sea state.
The area is an important refuge for diverse marine ecology, where coral reefs and marine species thrive without human disturbance. This untouched state makes the island valuable for marine researchers collecting unaltered data about natural ecosystems.
