Soft On Demand
In September 1999 at the age of thirty-one, Kawana entered the adult video (AV) industry with her release, "34 Year Old Mother Mariko" from Soft On Demand (SOD), one of the largest porn conglomerates in Japan. Her age made her one of the earliest AV actresses in the "mature woman" or "madame" (熟女 or jukujo) category of performers, whose popularity in Japanese porn began in the mid-1990s. She appeared in two early videos for Kuki Inc., one in the bukkake genre ("Mrs. Shower No. 1") and the other ("Lesbian Heaven Finger Love Vol.11"), was part of a lesbian series. In the softcore field, she starred in the pink film with Yōko Satomi which was released to theatres in March 2001.
