High-energy coastal zones often display rocky outcrops because fine sediments are rapidly transported away.
Sediment transport in the waters off Yonaguni is driven by strong currents and seasonal storms. These processes remove loose material from around exposed bedrock. Continuous scouring prevents significant sediment accumulation at the monument’s base. This clearing effect enhances the visibility of vertical walls and terraces. Geological models demonstrate that sediment-starved environments preserve relief more effectively than depositional zones. The monument’s dramatic exposure is therefore partly a product of ongoing sediment export. Its clarity underwater is maintained by relentless hydrodynamic cleansing.

The paradox is striking: constant motion preserves structure by stripping away obscuring debris. Rather than burying the monument, currents reveal it more sharply. The result is a formation that appears intentionally maintained. This dynamic equilibrium between erosion and exposure sustains its architectural illusion.
Sediment transport studies emphasize how coastal morphology depends on energy balance. Yonaguni occupies a high-energy regime where removal exceeds deposition. Such environments amplify geological forms into stark relief. The monument thus owes part of its mystique to oceanographic forces operating continuously across centuries.
