Ōmiyama ruins

Ōmiyama ruins is an archaeological site in Nagano Prefecture containing remains of pit dwellings, shell mounds, and ritual spaces positioned on elevated ground near water. The scattered discoveries across this terrain tell the story of long-term human settlement and daily activities over millennia.

The site documents the Jomon period spanning over 10,000 years, showing how hunter-gatherer societies gradually became settled communities. Archaeological layers reveal how living patterns and building methods changed over this vast stretch of time.

Jade beads and clay figurines discovered here reveal the craftsmanship of Jomon period people and their daily life. These objects hint at the spiritual beliefs and social connections that bound prehistoric communities together.

The site has interpretative displays and informational materials that explain the artifacts and their significance through visual presentations. Visiting during daylight allows you to see the actual excavation areas and read the explanatory plaques positioned throughout the grounds.

Geological study of jade artifacts found here reveals that prehistoric communities maintained trade connections across vast distances. This discovery challenges the idea that early societies were entirely isolated from one another.
