Tasuki (sash)

It is a sash made from either cloth or cord that loops over each shoulder and crosses over the wearer's back.

The bottom of the kimono sleeves can then be tucked into the loop, holding them back for convenience and functionality.

Terracotta Haniwa dating to the Kofun period that were excavated in Gunma Prefecture depict Shinto miko wearing tasuki.

[1] During the Edo period (1603–1867), tasuki were worn by manual laborers for the mobility they would have had if they were not wearing kimono.

Bōsōzoku motorcycle gang members wear tasuki for aesthetic reasons, as a part of their special attack clothing (特攻服, Tokkō-fuku),[3] an attempt to imitate World War II kamikaze pilots.
