You’ve seen it. A monster wave that curves like a Coney Island ride, swooping high, blue and white, its lacy crest like a hundred hands reaching toward shore. The Great Wave Off Kanagawa, a woodblock print, is the second most downloaded image from the Metropolitan Museum of Art’s online database. It’s also the most famous work made by Katsushika Hokusai, who during his long life, 1760 to 1849, produced thousands of other masterful and witty works. This exhibition presents 110 Hokusais from the British Museum’s collection together with masterpieces from collections in Japan. —Laura Jacobs
