About Yonaguni Monument in brief
Yonaguni Monument is a submerged rock formation off the coast of Yonaguni, the southernmost of the Ryukyu Islands, in Japan. Marine geologist Masaaki Kimura claims that the formations are man-made stepped monoliths. Geologist Robert Schoch believes that it is most likely natural. Neither the Japanese Agency for Cultural Affairs nor the government of Okinawa Prefecture recognise the features as important cultural artifacts. Neither government agency has carried out research or preservation work on the site. The formations are located below Arakawabana cliff which is the southern tip of YonAGuni island, with its main face oriented south-southeast.
It is composed of medium to very fine sandstones and mudstones of the Lower Miocene Yaeyama Group believed to have been deposited about 20 million years ago. It has become a popular diving location during the winter months because of its large population of hammerhead sharks. The formation has since become a relatively popular attraction for divers despite strong currents.
