This particular woodblock is one of the most recognized works of Japanese art in the world. It depicts an enormous wave threatening boats near the Japanese prefecture of Kanagawa.
While sometimes assumed to be a tsunami, the wave is, as the picture's title notes, more likely to be a large okinami – literally "wave of the open sea." As in all the prints in the series, it depicts the area around Mount Fuji under particular conditions, and the mountain itself appears in the background.
