Upon the death of Shunshō in 1793, Hokusai began exploring other styles of art, including European styles he was exposed to through French and Dutch copper engravings he was able to acquire. He was soon expelled from the Katsukawa school by Shunkō, the chief disciple of Shunshō, possibly due to his studies at the rival Kanō school. This event was, in his own words, inspirational: "What really motivated the development of my artistic style was the embarrassment I suffered at Shunkō's hands."
