A Japanese national identity is generally thought to have originated in the 17th century, with the advent of the Kokugaku movement. I will argue that there is earlier evidence for the existence of a Japanese national identity in the Kumano Nachi mandalas of the Kamakura and Muromachi periods. These mandalas employ the Nachi waterfall as a symbol of the strength and power of the Japanese land, counterbalancing Chinese Buddhist visual motifs. In this paper, I further assert that these mandalas are an early example of an artistic tradition of painting specific landscape features as symbols of a Japanese national identity, and that this tradition continues into the modern period.
