The main temple of the Rinzai sect, known as Daitoku-ji, is located on Mount Ryuhō. It was founded in the fourth year of the Shōwa era (1315) during the late Kamakura period, with the support of Akamatsu Enshin, the governor of Banshu, by the great monk Daitō Kokushi Sōhō Myōchō. Later, it received the deep devotion of Emperors Hanazono and Go-Daigo, becoming a temple of imperial prayer for both the Northern and Southern dynasties. During the Muromachi period, the temple fell into decay due to the Ōnin War, but it was revitalized by the monk Ikkyū. In the Momoyama period, Toyotomi Hideyoshi held the funeral for Oda Nobunaga here and established Sōkin-in to honor Nobunaga’s memory, along with donating temple lands. This led to a surge in the establishment of sub-temples by warlords, resulting in great prosperity for Daitoku-ji.
