The theme of clamming is often depicted in ukiyo-e. This work is well drawn to the end, and the mountains in the distance are casually eye-catching. Katsushika Hokusai (1760-1849) painted the mountains on the right side of the picture in the style of an ink painting. The mountains on the left, however, are painted in a Western-style. The sticky sky is also reminiscent of Western-style paintings in Japan at that time. In other words, this work uses Japanese, Chinese, and European paintings. It is hard to say whether it is a whim or a deliberate intention, but there is no doubt that this is a masterpiece that conveys a part of Hokusai’s extraordinary study of painting techniques.
