There is an elephant on Mukuchi Island, approximately two kilometers south of Port Shimotsui-upon learning this, KJ editing staff chartered a boat to the island and successfully recorded the elephant on film! Which is actually not an achievement at all, for the elephant we refer to here is a rare stone named "Zo-iwa (Elephant Stone)" naturally shaped like an elephant and designated as natural treasure. Its appearance, in any case, is nothing but an elephant. Incidentally, the Inland Sea was land during the Old Stone Age, populated by various creatures. It is now known that among the creatures were Naumann elephants. Is there, by chance, any connection between the Zo-iwa and the Naumanns?
