Bijin-ga (美人画, "beautiful person picture") is a generic term for pictures of beautiful women. Nearly all ukiyo-e artists produced bijin-ga, it being one of the central themes of the genre. However, a few, including Utamaro, Suzuki Harunobu, Itō Shinsui, Toyohara Chikanobu, Uemura Shōen and Torii Kiyonaga, have been described as the greatest innovators and masters of the form.
