Atamadai Shell Mound


Atamadai Shell Mound

Atamadai Shell Mound was first excavated by Tokyo Imperial University (present-day University of Tokyo) in 1894. Since then, there have been numerous excavations that have uncovered many earthenware, stoneware, and shell bracelets. The earthenware in this mound was representative of the early Middle Jōmon sub-period (2500 BC – 1500 BC) earthenware found throughout eastern Kanto. As such, this style of earthenware was named Atamadai pottery and this shell mound became known throughout the nation as the type site for Atamadai pottery. In 1968, Atamadai Shell Mound was nationally designated as a historic site.

The plum trees and daffodils planted here produce beautiful flowers in the spring. There are 600 plum trees, representing about 30 different species, which bloom from mid-January to late February.
