ヘラ状垂飾 (hera-jō suishoku): 'spatula-shaped pendant'

Read the wear and the blade gives itself up. Around the hole of this hand-length slat of imported serpentinite, the cord-groove bites at a stubborn forty-five degrees across both faces — not the straight overhead rub a dangling pendant leaves, but the mark of something held taut and pressed to the body, day after day. Excavators lifted it from a pit at Yamaguchidai in Kawasaki, one of five such large Jōmon ornaments, and read it not as a whirled voice on a cord but as a personal emblem: precious foreign stone worn at the hip to mark who you were.
