Yonaguni Monument
MegalithicAsia
Submerged rock formation off Japan with apparent terraces, right angles, and carved features. Debated: natural geology or a 10,000-year-old man-made structure lost to rising seas.
Look Closer — this site carries open questions: stones heavier than the period's tools could lift; stones fitted without mortar, almost no gap; geometry beyond period explanation.
