This video was released in August of 2014 and is part of the Yukimura Ryuu series. In these videos, Yukimura demonstrates how to use basic ties in the context of homes. Other videos focus on tying to tables or chairs. This video focuses on the kamoi (鴨居) which is the upper rail of the door in Japanese homes. This point serves as a hard point for Japanese rope bondage suspensions.
In this video, Yukimura works with six different models, demonstrating both his classic style of tying as well as how to incorporate the kamoi in to partial suspensions.
