[2] Nanki-Katsuura Onsen is located within Yoshino-Kumano National Park and Nanki-Kumano Geopark.
The area surrounding Nanki-Katsuura Onsen has a very long history, and many of the temples nearby are protected as the Sacred Sites and Pilgrimage Routes in the Kii Mountain Range.
The onsen town itself, which dates back to the Edo Period, has more than one hundred springs overlooking the Pacific Ocean.
[3] These springs are scattered among the rugged terrain, including a peninsula known as Urashima (浦島) and an island known as Nakanoshima (中ノ島).
[5] Nanki-Katsuura Onsen can be reached via Japan National Route 42 by road, or through Kii-Katsuura Station on the Kisei Main Line.
