Fudarakusan-ji (補陀洛山寺, Fudarakusan-ji) is a Tendai Buddhist temple in Higashimuro District, Wakayama Prefecture, and one of the sacred sites linked to the Kii Mountain pilgrimage network. Its name refers to Mount Potalaka, the legendary home of Kannon, and the temple is traditionally said to have been founded by the Indian monk Ragyō Shōnin. The temple is known for its religious role in Kannon worship and its association with Japanese pilgrimage culture. In 2004, it was inscribed on the UNESCO World Heritage list as part of Sacred Sites and Pilgrimage Routes in the Kii Mountain Range. The site is a modest temple rather than a large complex, but its significance lies in its history and religious associations. Its UNESCO status places it within one of Japan’s best-known sacred landscape routes.
