石斧型垂飾 (sekifu-gata suishoku): 'stone-axe-shaped pendant'

Urahoro's Heiwa site contributes a whole small corpus to the perforated-slat question: the modern comparative table lists a thick ten-centimetre fragment with a sawn-through hole, slats of 6.8, 6.0 and 4.5 centimetres, some with unfinished drilling — mostly logged as rhyolite, one flagged as possibly Hidaka jade, all under the perforated stone axe label. It was one of these that reached the newspapers in 2000 as a 'soft jade' ornament, before geologists pointed out how often Hokkaido's look-alike greenstones fool the eye. One site, one horizon, repeated thin end-holed blades in graded sizes: the pattern of a local tradition of suspended slat objects, whatever those objects did.

Object
石斧型垂飾; 短冊形の垂飾; 軟玉製装飾品; 有孔石斧. Specimens/count: one newspaper-illustrated top-holed slat plus multiple Heiwa perforated-axe/slat fragments in Esashi comparative table. Material: mostly rhyolite in Esashi table; one row marked possible Hidaka jade; newspaper reports Hidaka nephrite/soft jade with geology caution. Dimensions: Esashi table Heiwa rows include (10.0) x (4.2) x (2.2) cm fragment with rubbed-cut hole; 6.8 x 2.4 x 0.9 cm; 6.0 x 1.8 x 0.6 cm possible Hidaka jade; 4.5 x 1.4 x 0.3 cm. Perforation: newspaper image shows small upper hole; Esashi table row 16 has rubbed-cut hole, rows 26/28/29/34/35 have rubbed-cut traces or unfinished perforation evidence. Context: Heiwa site; Esashi table attributes rows to Urahoro town education reports 1960 and 1971 and Shimokorobe-type Early Jomon context. Date: Initial Jōmon (早期), shell-impressed-pottery horizon; the perforated-axe class bracket is c. 7050–5950 BC in the Esashi 2020 chronology.
Function
