Utamaro's Ase o fuku onna ("Woman wiping sweat"), an example of bijinga (literally, "pictures of beautiful people"), a central theme of the ukiyo-e genre of Japanese art. Nearly all ukiyo-e artists produced bijinga, but a few, including Utamaro, Suzuki Harunobu, Toyohara Chikanobu, and Torii Kiyonaga, are widely regarded as the greatest innovators and masters of the form.
