Iwajuku Site, Archaeological site in Midori, Japan
The Iwajuku Site occupies a small hill near Mount Akagi, with excavation areas divided into northern and southern sections along the Watarase River.
The site's 1946 discovery by amateur archaeologist Tadahiro Aizawa proved human habitation in Japan during the Paleolithic period, contradicting previous theories.
Archaeological investigations revealed two distinct stone tool cultures from different periods, showing technological evolution between 30,000 and 20,000 years ago.
The Iwajuku Dome museum displays archaeological findings and geological cross-sections, operating from 9:30 to 17:00 with free admission and parking facilities.
Excavations uncovered oval stone axes and harvesting tools in the lower black-brown layer, indicating extensive plant resource utilization 30,000 years ago.
