The Kaitei Iseki were discovered by chance in 1985 by marine explorer Aratake Kihachirō. Some claim that these ruins, which look like giant blocks or steps of a sunken pyramid, are the remains of a Pacific Atlantis, although there are equally compelling arguments that they are just the random result of geological processes.

One Yonaguni dive shop with English-speaking guides is Sou Wes , who also offers glass-bottomed boat tours over the ruins for nondivers. When the visibility is poor due to choppy water, passengers can watch a DVD about the ruins on board. Mosura no Tamago also offers glass-bottomed boat tours
