Kimiko Matsuzaka

Kimiko Matsuzaka (松坂 季実子, Matsuzaka Kimiko) is a Japanese AV idol who was prominent during the late-1980s and early-1990s noted for her large breasts. Authorities on the AV point to Matsuzaka's career as the beginning of the "Big Bust Boom" in Japan.

Kimiko Matsuzaka made her last AV, Sexual Game, in October of 1990. AV director Toru Muranishi called her departure from the industry one of the worst news items affecting the AV industry in 1990. A year and eight months after her debut, she had starred in 21 AVs, helping to build Muranishi's company, Diamond Image, into the largest AV company in Japan. Within a year after Matsuzaka's departure, Diamond Image would declare bankruptcy. After retirement from AV appearances, she appeared with Kaoru Kuroki at the Akasaka club, "Mirukuhooru" ("Milk Hall"). She ceased all public appearances in the spring of 1991, citing personal problems. It was later reported that she had taken up work as a commuting office lady.
