Alice Japan
However, the pink film industry was in decline due to the rise of the adult video (AV) and Mochizuki decided to join the AV market, starting up his own production company, E-Staff Union (). With the difficulties of surviving in the Japanese film industry of the time, Mochizuki went into the AV business primarily to make some money while directing films and although he expressed some doubts about his choice he has said that if he "wanted to keep making them [films], it was either the sexy stuff or nothing." In 1987, Mochizuki was directing AVs for Alice Japan, a company founded in 1986 as the adult video arm of Japan Home Video. He started the "Flashback" () series for Alice Japan in August 1987 and had produced Volume 30 in the series by December 1990 including one with the 1980s AV Idol Nao Saejima. In April 1990, he directed another early AV Idol, Yumika Hayashi, in the Alice Japan video "The Contrary Soap Heaven 5" and he remained very active with Alice Japan through 1991.
