Further to my post regarding 'Hojōjutsu' (捕縄術 - "Restraining Rope Technique"), including accompanying pictures from Draeger (1974). I should add that the 1987 version of the 'Keisatsu Taiho-jutsu Kyōkasho' (translated into English), shows the suspect having the rope applied around the waist, as opposed to the neck / throat.
