Raiyu ［頼瑜］ (1226–1304): A priest who developed the doctrinal basis of the New Doctrine (Shingi) branch of the True Word (Shingon) school in Japan, and the restorer of Daidembō-in temple, also known as Negoro-ji temple. After becoming a priest of Daidembō-in at Mount Kōya, Raiyu engaged in the doctrinal study of Esoteric Buddhism. Beginning around 1249, he visited Tōdai-ji, Kōfuku-ji, Ninna-ji, and other temples to further his studies not only in Esoteric Buddhism but also in other doctrines. In 1266 he became chief instructor of Daidembō-in and later founded a school of esoteric practice named the Chūshō-in school after his lodging temple. In 1288 Raiyu moved Daidembō-in from Mount Kōya to Mount Negoro. Kakuban (1095–1143), the founder of Daidembō-in at Mount Kōya, had once resided at Mount Negoro in his later years. The moving of Daidembō-in to Mount Negoro effectively put an end to a 150-year dispute between that temple and Kongōbu-ji on Mount Kōya.
