Dr Robert Schoch believes that Yonaguni is a naturally-occurring phenomenon and has argued that if the city was manmade, it would have been before the Ice Age.While Kimura has claimed to have identified ruins of a castle, arched entrances, five temples, at least one large stadium, and narrow passageways, Dr Schoch argues that the 'steps' of the pyramid are simply the result of erosion.
