Kinbaku shashin
Kinbaku photography, the photographic genre of rope bondage that grew from Itō Seiu's era through postwar SM magazines to art photographers such as Araki Nobuyoshi.
Kinbaku shashin means kinbaku photography. The phrase appears in the romanized title of Akita Masami’s 1996 book Nihon Kinbaku Shashin-shi, rendered as “The History of Japanese Bondage Photography”, which a bookseller describes as tracing the genre from the early postwar years of Itō Seiu and Minomura Kō onward. The same listing notes the book’s many examples of bondage photography from SM magazines across the second half of the 20th century.
Wikipedia credits 1950s magazines such as Kitan Club with spreading kinbaku through drawings and photographs. A USC online exhibition by Sui Wang discusses kinbaku in its section on the photographer Araki Nobuyoshi, and the Yokohama Museum of Art holds his 2008 Bondage Forgery A, which, the museum’s record says, extended his existing Bondage series.
