Katsushika Hokusai (1760 — 1849) was an Edo period Japanese artist, painter, woodblock printmaker and ukiyo-e maker. Born in Edo (now Tokyo), Hokusai is best-known as author of the woodblock print series Thirty-six Views of Mount Fuji (c. 1831).

Through his painter life, Hokusai switched his pseudonoms thirty times. Among them, Hokusai (used 1805-1810) is today preferably used to address him.
