Tekubi 手首
Japanese for wrist; in kinbaku vocabulary tekubi marks where the rope sits and appears in tie names such as ryō tekubi shibari, a binding of both wrists together.
Tekubi (手首) is the ordinary Japanese word for wrist (Jisho), written with the characters for hand and neck. SMpedia files it among the words that name where rope is placed and calls it nearly synonymous with kote, which Shibari Study glosses as the forearm, the word heard in takate kote. Shibari Study lists tekubi in its anatomy vocabulary, Shibari Mallorca glosses it as wrist, and it appears in tie names: Shibari Study gives ryō tekubi shibari (両手首縛り) and Andrea Ropes ryo-tekubi for tying the two wrists together, and Andrea Ropes describes koutoubu ryō tekubi shibari, with the bound wrists placed at the back of the neck.
