Submarine Ruins (Yonaguni Island)

These are the mysterious structures called “Submarine Ruins” that lie submerged just 100 meters off the cape of Arakawabana on the south coast of Yonaguni Island. It is still shrouded in mystery whether they are artificially made historical ruins or a product of nature. It is a mysterious world on the reef where you can see stairs and terrace-like things. It is also possible to see the Submarine Ruins by diving or by glass bottom boat.
