| Yonaguni (与那国町, Yonaguni-chō, Yonaguni: Dunan, older Juni, Yaeyama: Yunoon, Okinawan: Yunaguni) is a town located entirely on Yonaguni Island in Yaeyama District, Okinawa Prefecture, Japan. It is the westernmost municipality in Japan, and is known for billfish fishing and as a diving spot. In 1987, divers discovered the Yonaguni Monument, a rock formation that some believe may be man-made.
It is also home to two Ryūkyūan writing systems, pictographic "kaida-di" (also used on Ishigaki and Taketomi islands where it is called "kaida-ji") and the symbols used to indicate family names, "dāhan" (also used on Ishigaki Island where they are called "yāban"). |
