Radiometric dating methods measure isotopic decay within minerals to determine geological age.
Radiometric dating determines the age of rock formation but not necessarily when surfaces were modified. The Yonaguni Monument’s sandstone can be dated to the Miocene epoch, yet surface alteration lacks clear datable material. Underwater conditions further complicate sampling. Without organic residues or tool marks containing datable elements, precise chronology remains elusive. This limitation sustains uncertainty regarding potential human modification. Geological age alone does not resolve archaeological questions. The monument therefore occupies a methodological gray zone.

The inability to directly date surface shaping intensifies debate. In terrestrial archaeology, charcoal or organic remains anchor timelines. At Yonaguni, such materials are absent or inaccessible. The structure’s scale contrasts sharply with the scarcity of definitive chronological evidence.
This dating dilemma reflects broader challenges in underwater archaeology. Many submerged landscapes lack clear stratigraphy or recoverable artifacts. Yonaguni exemplifies how technical constraints can prolong controversy. Until new dating techniques emerge, its timeline will remain partly indeterminate.
