fabric shaku; textile shaku
Obsolete unit of length used for measuring cloth, approximately 36.4 cm. Slightly longer than the standard shaku (approx. 30.3 cm).
In Edo-period kimono shops, they measured fabric using the gofukujaku.
Compound of 呉服 (gofuku, 'kimono fabric') and 尺 (shaku, a traditional unit of length). The exact historical derivation is uncertain, but the term reflects its specialized use in the textile trade.
