Ukete 受け手
"Receiving hand": a neutral, gender-free Japanese term for the person being tied, the counterpart of shibarite.
Ukete is an ordinary Japanese word for a receiver or the receiving side (Jisho). Kinbakuwiki, drawing on the teacher Harukumo, describes it as the most neutral name for the person in rope: it carries no commercial, professional or hierarchical meaning and no gender, and teachers including Harukumo and Osada Steve prefer it. The same source says that in Japan ukete, M-jō and moderu are the usual words, and that rope bunny is not used there. Kinbakuwiki writes the word 受けて; the dictionary form is 受け手.
