Bakushi 縛師
Short form of kinbakushi, "kinbaku master"; a name used, like nawashi, for people who perform Japanese rope bondage.
Bakushi is a shortened form of kinbakushi (緊縛師), a word for a master of kinbaku. Wikipedia notes that today’s kinbaku performers are often called either nawashi or bakushi. In at least one lineage the name was also given: Shibari Dojo records that Yukimura Haruki granted bakushi names, along with permission to teach, to only a few of his students.
