Nachi-Katsuura is a town on the southeastern coast of the Kii Peninsula, best known for its onsen (hot springs) and its fishing industry.
It is near by the Kumano Nachi Taisha; one of the three Kumano shrines, situated a few kilometers inland from the coastal hot spring resort of Katsuura. The shrine is part of a large complex of neighboring religious sites that exemplify the fusion of Buddhist and Shinto influences that is particular to the Kumano region. The site also boasts the tallest waterfall in Japan.
