Nanpo Jōmyō 南浦紹明 (1235–1308) — Kamakura-period Japanese Rinzai-Zen master, posthumous imperial titles Entsū Daiō Kokushi 圓通大應國師 (“National Master Universal-Penetrating Great-Response”) and Daiō Kokushi 大應國師.
Born 1235 in Suruga Province. Ordained at Kenchō-ji in Kamakura under 道隆 Lánxī Dàolóng (Rankei Dōryū). Travelled to Song-dynasty China in 1259; received Línjì-school transmission from Xūtáng Zhìyú 虛堂智愚 (1185–1269) at Jìngshānsì 徑山寺 — the Xūtáng line of Línjì Zen, which through Nanpo’s transmission became the principal Japanese Rinzai-Zen lineage of the medieval Gozan system. Returned to Japan in 1267. Founded Kōtoku-ji 興德寺 in Hakata; later resided at Kenchō-ji in Kamakura. Died 1308 at age 74.
His Recorded Sayings — Entsū Daiō Kokushi goroku 圓通大應國師語錄 (KR6t0254, T80n2548) — two fascicles, were compiled by his disciple Soshō 祖照 (and others). The Xūtáng-Nanpo line through his disciple Shūhō Myōchō 宗峰妙超 (Daitō Kokushi, 1282–1338) — founder of Daitoku-ji — and Shūhō’s disciple Kanzan Egen 關山慧玄 (1277–1360) — founder of Myōshin-ji — produced the Ō-tō-kan 應燈關 (“the Daiō, Daitō, Kanzan triple-lineage”) which became the principal medieval and modern Japanese Rinzai-Zen lineage.
