Hokusai was a Japanese master artist and printmaker active in the 19th century who is considered one of the most prominent figures in ukiyo-e art. He produced thousands of paintings, sketches, and woodblock prints over his long career, including his famous series "Thirty-Six Views of Mount Fuji" published between 1826-1833. Hokusai had a restless nature and was constantly striving to improve his art, believing he made his greatest progress after age 90. He embodied the essence of the Ukiyo-e school during its development and has been a major influence on Western art since the 19th century.
