Sannō-Gakoi Site

The Sannō-Gakoi Site stands on a river terrace along the north bank of the Nakasaki River, containing remains from the late Jōmon to Yayoi periods.

The excavations in 1965 by Tohoku University uncovered large quantities of nuts, animal bones, over 400 pottery pieces, and more than one thousand stone tools.

The site reveals settlement patterns through multiple archaeological layers, featuring preserved fragments of knitted cloth, early lacquerware, combs, and vermilion-painted hairpins.

Visitors can reach the Sanno Historic Park Ayame Garden by taking a 20-minute car ride from JR East Tohoku Shinkansen Kurikoma-Kōgen Station.

A three-meter thick peat layer at the site preserved organic materials, providing direct evidence of daily life during the Jōmon period in northern Japan.
