By 1980, Nami Matsukawa was a sex worker named "Emi" at the SM club Blue Chateau in Akasaka, Tokyo.
[1] Matsukawa made her Nikkatsu debut with Masaru Konuma's 1982 Slave Contract (奴隷契約書), to be later promoted as the fourth "SM Queen" (SMの女王, SM no joō) following Naomi Tani, Junko Mabuki, and Izumi Shima.
She also performed as a bondage model for nawashi Hiroshi Urado in the SM Fairy Nami Matsukawa (SMの妖精・松川ナミ) series of Nikkatsu Video in 1982.
Her girl-next door quality made her popular with audiences, but SM-author Oniroku Dan complained that, unlike the buxom Naomi Tani, Matsukawa was not fleshy enough to be an appealing bondage subject in his films.
[2] Rope and Breasts of Konuma was Matsukawa's farewell appearance as the Nikkatsu SM Queen[3] and she was replaced by Miki Takakura after a brief "reign".
