About 100 original prints of The Great Wave off Kanagawa are estimated to survive today.
Hokusai’s image was not a unique painting but a mass-produced ukiyo-e woodblock print. Thousands of impressions could be pulled from the carved blocks, yet repeated printing wore down the blocks and produced differences in line sharpness and color among surviving copies.
The exact total is not fixed. Research cited for the work identifies roughly 113 surviving first-edition impressions as of 2022, so “about 100” is the appropriate rounded quiz answer. Copies are held by major institutions including the British Museum, the Metropolitan Museum of Art, the Tokyo National Museum, and the Rijksmuseum.
That survival count refers to original Edo-period impressions, not modern posters, reproductions, or digital images. The print’s extraordinary fame has made it one of the most reproduced images in art, but modern copies do not increase the number of surviving originals.
