She teamed up with "AV Queen" Hitomi Kobayashi in the February 2001 theatrical release, "Kyōko Aizome vs. Hitomi Kobayashi: Sexual Excitement Competition" (愛染恭子ＶＳ小林ひとみ　発情くらべ). Aizome both starred in and directed the film, which was released by Nikkatsu's post-"Roman porn" distributor of theatrical pornography, Excess films. An adult video starring the two actresses and also directed by Aizome followed in March. Entitled "Lesbian Wives", the video had Aizome and Kobayashi playing the wives of two "yakuza" bosses who become engaged in a lesbian relationship. Two years later, she directed the AV "Lesbian Politicians" (2003), in which she also co-starred with the popular award-winning AV actress Ai Kurosawa. In late 2003, she directed and co-starred with another "mature" AV actress, Eri Kikuchi, in the softcore film "Double G-Spot: Kyôko Aizome vs. Eri Kikuchi".
