Sin is a professional kinbakushi resident in Germany. He regularly demonstrates the deeply erotic kan’nonawa style of kinbaku on the international underground scene and provides sessions for clients with total discretion. He does not wish to be seen as an authority and avoids teaching and imagery. Sin is the author of "Year of The Bakushi", a detailed account of the human elements of kinbaku BDSM sexual bondage, and is the technical consultant to 天つ縄 AMATSUNAWA.
Kinbaku Today was founded in 2014 to promote kinbaku, the art of Japanese erotic rope bondage, to the Western-speaking world.
Since its inception, Zetsu has served as the founding editor for the site, publishing contributions from authors in the US, Europe, Australia, and Japan.
The goal of the site is to provide a forum where people can read announcements about events, books, and video releases, read interviews with Japanese bakushi and models, study tutorials, view galleries of both Western and Japanese rope artists, and learn more about the history of the art of kinbaku.
