Although the site is on the sea floor, the continuous shapes of the formations look as if they were cut and shaped from stone, leading some to believe that it is difficult to believe that the formations were formed by nature alone.

Another evidence is the wedge-shaped pit found on the rock face.

The natural landform theory holds that the bedrock has a direction (nodule) that tends to break easily, and that erosion caused by waves and currents over the years has formed landforms that appear stair-like or straight.

Furthermore, the entire topography is tilted approximately 10-15 degrees to the southeast, which is consistent with the tilt of fault zones in the Yaeyama area, and is one of the reasons why it is considered to be due to natural geological structures.

It has been pointed out that even the areas that appear to be pits may have been created by erosion or biological activity, and the fact that man-made-looking shapes are not necessarily the result of human handiwork adds to the mystique of this submarine topography.
