Influences on art and culture

Hokusai had achievements in various fields as an artist. He made designs for book illustrations and woodblock prints, sketches, and painting for over 70 years. Hokusai was an early experimenter with western linear perspective among Japanese artists. Hokusai himself was influenced by Sesshū Tōyō and other styles of Chinese painting. His influences stretched across the globe to his western contemporaries in nineteenth-century Europe with Japonism, which started with a craze for collecting Japanese art, particularly ukiyo-e. Some of the first samples were to be seen in Paris, when in about 1856, the French printmaker, designer and colleague of many Impressionsist artists such as Édouard Manet, Félix Bracquemond first came across a copy of a Hokusai sketchbook at the workshop of August Dalatre, his printer.

With the sketchbook as his influence Bracquemond designed the "Rousseau Service", an elegant set of dinnerware, on behalf of Francois-Eugene Rousseau, the owner of a glass and ceramics shop. Exhibited at the Universal Exposition in Paris in 1867, the Rousseau Service was a success both critically and commercially and was reissued in several editions over the years. The Rousseau Service featured images of birds and fish copied from the Japanese book illustrations and placed asymmetrically against a white background for a look that would have been very modern at that time.

Hokusai also influenced the Impressionism movement, with themes echoing his work appearing in the work of Claude Monet and Pierre-Auguste Renoir, as well as Art Nouveau, or Jugendstil in Germany. His woodcuts were collected by many European artists, including Degas, Gauguin, Klimt, Franz Marc, August Macke, Édouard Manet, and van Gogh. Degas said of him, "Hokusai is not just one artist among others in the Floating World. He is an island, a continent, a whole world in himself". Hermann Obrist 's whiplash motif, or Peitschenhieb, which came to exemplify the new movement, is visibly influenced by Hokusai's work.

The French composer Claude Debussy 's tone poem La Mer, which debuted in 1905, is believed to have been inspired by Hokusai's print The Great Wave. The composer had an impression of it hanging in his living room and specifically requested that it be used on the cover of the published score, which was widely distributed, and the music itself incorporated Japanese-inflected harmonies.

Even after his death, exhibitions of his artworks continue to grow. In 2005, Tokyo National Museum held a Hokusai exhibition which had the largest number of visitors of any exhibit there that year. Several paintings from the Tokyo exhibition were also exhibited in the United Kingdom. The British Museum held the first exhibition of Hokusai's later year artworks including 'The Great Wave' in 2017.

Hokusai inspired the Hugo Award –winning short story by science fiction author Roger Zelazny, " 24 Views of Mt. Fuji, by Hokusai ", in which the protagonist tours the area surrounding Mount Fuji, stopping at locations painted by Hokusai. A 2011 book on mindfulness closes with the poem "Hokusai Says" by Roger Keyes, preceded with the explanation that "ometimes poetry captures the soul of an idea better than anything else".

In the 1985 Encyclopædia Britannica, Richard Lane characterizes Hokusai as "since the later 19th century impressed Western artists, critics and art lovers alike, more, possibly, than any other single Asian artist".

'Store Selling Picture Books and Ukiyo-e' by Hokusai shows how ukiyo-e during the time was actually sold; it shows how these prints were sold at local shops, and ordinary people could buy ukiyo-e. Unusually in this image, Hokusai used a hand-colored approach instead of using several separated woodblocks.

His youngest daughter Ei has her own manga and film called Miss Hokusai.

A biographical film about the painter was released in Japan on May 28, 2021. It was premiered at the 33rd Tokyo International Film Festival.
