Mt. Kuromata
MegalithicAsia
The 'Pyramid of Japan' — a near-perfect pyramidal hill in Akita Prefecture, close to the Ōyu Stone Circles. Locals consider it sacred. Alt-archaeology research suggests artificial construction or modification; mainstream geology argues natural erosion. Ground-penetrating radar has revealed unusual internal structure.
Look Closer — this site carries open questions: stones heavier than the period's tools could lift; geometry beyond period explanation.
