This work is one of the representative works of Katsushika Hokusai, a Japanese ukiyo-e artist. It depicts a Kappa, a legendary water creature known for its distinctive appearance and mischievous personality. The Kappa in this painting has large eyes, a wide mouth, and a turtle shell-like back. The background of the painting is a sepia tone, resembling old paper or cloth, which adds to the antiquity and mystery of the work. Hokusai was one of the most famous ukiyo-e artists of the Edo period, and his works had a profound impact on posterity.
