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

Twin oblique scars, raked to almost 45 degrees, are worn into both faces of this serpentinite blade around its suspension hole — the signature it shares with four other oversized pendants from the Kanto and Gunma hills. That wear is what invites the bullroarer comparison; the archaeologist who studied the group read it otherwise, as a cord held taut with the blade pressed against the body, marking a waist ornament worn day to day and cut from green stone carried in from afar, probably a personal badge. Alone among the five, the Yokohama piece was never laid in a pit.

Particulars

Object
A large serpentinite blade, over 10 cm long, pierced once near the top; around the hole, both faces are worn in a slant of nearly 45 degrees. Late Early to initial Middle Jōmon.
Function
Published as a hera-shaped pendant within the five-object Kanto/Gunma cluster; carries the same bilateral oblique wear, without the secure pit context of its four companions.
