Hotaru Hazuki

In recent years Hazuki has appeared in mainstream films such as Man Walking on Snow, which screened in the Un Certain Regard section at the 2001 Cannes Film Festival. The cast listing gives her name as Sayoko Ishii.

She became closely associated with the work of Toshiki Satō, starring in some of his highest-regarded films, including the Pink Grand Prix Best Film-winners Blissful Genuine Sex: Penetration! (1995) and Adultery Diary: One More Time While I'm Still Wet (1996). Hazuki was given the Best Actress award for her work in both films. Her work in Satō's Apartment Wife: Midday Adultery (1997), Ueno's The Lustful Sister-in-Law 2: Erotic Games (1999) and pink film actor-director Yutaka Ikejima's Obscene Stalker: It Holds in Darkness! (2002) won her the Best Actress Silver Prize in three more of the annual ceremonies.

Hazuki made her screen debut in director Takahisa Zeze's 1993 film Modern Story About Bandits aka The Legend of the Thief. Her role in Toshiya Ueno's Keep on Masturbating: Non-Stop Pleasure (1994) won her the Best New Actress, 2nd Place at the Pink Grand Prix. To pink film audiences she is known less for her beauty than for her strong stage presence and unique vocal performance. Anglophone pink film critic Jasper Sharp notes her "aloof, composed and slightly melancholic figure."

Hotaru Hazuki was born in Fukushima Prefecture in 1970 as Sayoko Ishii (石井佐代子 , Ishii Sayoko) . She joined the Suizokukan Gekijō (Aquarium Theater) theatrical group while in university. Besides performing in the groups' productions, she works as co-organizer. She uses her birth name in her stage career.
