Su origen sigue discutido y conviene reflejarlo con honestidad: el geólogo marino Masaaki Kimura, de la Universidad de las Ryukyu, defiende tras dos décadas de estudio que fue tallada cuando la zona estaba emergida, hace unos 10.000 años. Otros especialistas, como Robert Schoch y Patrick D. Nunn, sostienen que es enteramente natural: la arenisca está atravesada por juntas paralelas verticales que fracturan la roca en bloques rectangulares, y Yonaguni está en una región sísmica. Hay formaciones escalonadas semejantes en tierra, en Sanninudai.
