Hiromi Toshikawa (利川 裕美 Toshikawa Hiromi), born 1976 in Tokyo, better known as Hiromix (ヒロミックス, Hiromikkusu), is a Japanese photographer and artist.

Born in 1976, Hiromix rose to fame in Japan after winning the 11th New Cosmos of Photography (写真新世紀, Shashin Shin-seiki) award, hosted by the photographic manufacturer Canon, in March 1995. Hiromix was nominated by Nobuyoshi Araki, one of Japan’s best known photographers, for a series of photographs called Seventeen Girl Days. Through her provocative photographs depicting the life from a teenager’s perspective, Hiromix became a media sensation and pop cultural icon in Japan.

Hiromix spearheaded a movement that redefined Japanese photography. By turning her lens on herself, her friends, and the messy beauty of the everyday, she legitimized the “photo diary” style. Her work inspired a generation of young women to pick up point-and-shoot cameras and document their own lives, proving that art didn’t need to be polished—it just had to be real.
