Uramado 裏窓
Tokyo SM magazine published by Kubo Shoten from 1956 to 1965, founded by Suma Toshiyuki and later edited by Iida Toyoichi (Nureki Chimuo).
Uramado (“Rear Window”) was a monthly magazine from the Tokyo publisher Kubo Shoten, which shared offices and staff with the sexology publisher Amatoria-sha. The National Diet Library holds it under the English subtitle “the Japan’s most remarkable S-M magazine” and dates the run from 1956 to 1965.
It began in 1956 under the title Kappa and took the name Uramado later that year after the publisher Kōbunsha objected to the first title. Japanese Wikipedia’s article on Kubo Shoten says the new name came from the Hitchcock film, a favorite of the founding editor Suma Toshiyuki, who also worked under the names Minomura Kō and Kita Reiko. Suma brought contacts from Kitan Club and Fūzoku Zōshi, and the illustrator Muku Yōji joined the editorial staff in 1963.
Japanese Wikipedia describes it as a popular-fiction magazine at first, and its article on Suma as mystery fare; it then moved steadily toward SM content. Iida Toyoichi, later known as Nureki Chimuo, first wrote for it in 1957; the historian Kawahara Azumi dates his appointment as editor-in-chief to January 1962. Police raids and a campaign against “harmful books” that began in 1963 put pressure on the title, and the last issue under the Uramado name is dated January 1965. Kubo Shoten continued the line with Suspense Magazine.
