Kawanabe Kyōsai(河鍋 暁斎?, May 18, 1831 – April 26, 1889) was a Japanese artist, in the words of a critic, "an individualist and an independent, perhaps the last virtuoso in traditional Japanese painting".
Living through the Edo period to the Meiji period, Kyōsai witnessed Japan transform itself from a feudal country into a modern state. Born at Koga, he was the son of a samurai. His first aesthetic shock was at the age of nine when he picked up a human head apart from a corpse in the Kanda river. After working for a short time as a boy with Utagawa Kuniyoshi, he received his artistic training in the Kanō school, but soon abandoned the formal traditions for the greater freedom of the popular school. During the political ferment which produced and followed the revolution of 1867, Kyōsai attained a reputation as a caricaturist. His very long painting on makimono "The battle of the farts" may be seen as a caricature of this ferment. He was arrested three times and imprisoned by the authorities of the shogunate. Soon after the assumption of effective power by the Emperor, a great congress of painters and men of letters was held at which Kyōsai was present. He again expressed his opinion of the new movement in a caricature, which had a great popular success, but also brought him into the hands of the police this time of the opposite party.
Kyōsai is considered by many to be the greatest successor of Hokusai (of whom, however, he was not a pupil), as well as the first political caricaturist of Japan. His work mirrored his life in its wild and undisciplined nature, and occasionally reflected his love of drink. Although he did not possess Hokusai's dignity, power or reticence, he compensated with a fantastic exuberance, which always lent interest to his technically excellent draughtsmanship.
