有孔石斧 (yūkō sekifu): 'perforated stone axe'
Five perforated polished 'axes' from northern Tōhoku and southern Hokkaido — Nakano B, Shimotashiro and Uriba — appear together in an Aomori research bulletin. The materials disagree agreeably: tuff at 8.2 centimetres, serpentinite at 5.1 and 4.9, and green tuff in a fragment — the same top-holed thin-blade format repeated in different stones, two of them rubbed smooth at the hole as if by a cord. The perforated-axe label covers them all; what it does not explain is why an 'axe' should hang from a cord by its head.
Particulars
- Object
- Five perforated polished stone blades of the Initial Jōmon, from Nakano B, Shimotashiro and Uriba. The three Nakano B pieces are 8.2 cm of tuff (15.9 g), 5.1 cm of serpentinite (21.4 g) and 4.9 cm of serpentinite (25.7 g), each bored with a single hole at the head or upper corner, two of them worn smooth around the bore; the Shimotashiro piece is a green-tuff head fragment with one perforation, 4.7 × 4.3 × 2.3 cm as preserved and 37 g. The fifth blade, from Uriba, remains unresolved. Nakano B was occupied c. 5550–5050 BC, and the perforated-axe class as a whole spans roughly 8,500 to 6,000 years ago.
- Function
- Published as perforated polished stone axes (有孔石斧) in an Aomori study comparing end-holed blades from Nakano B, Shimotashiro and Uriba; ancient use is unresolved.
