Mugaku Sogen (1226–1286), a Song-Chinese Rinzai monk born in Mingzhou (Ningbo), is famous for the episode where, when Yuan soldiers pressed blades against him during the Mongol invasion of Southern Song, he remained utterly calm and said ‘Makubonno’ (Do not be troubled). This story reached the eighth Kamakura regent Hojo Tokimune, who invited Mugaku to Japan in 1279 to be his Zen master during the existential crisis of the two Mongol invasions (1274 and 1281). After the second invasion was repelled, Tokimune in 1282 founded Engakuji in Kamakura not only for the Japanese war dead but also for the souls of the Mongol and Koryo fallen — a profound expression of universal Buddhist compassion guided by Mugaku. Mugaku served as founding abbot until his death in 1286, receiving the posthumous title ‘Bukko Kokushi.’ Visit Engakuji in Kita-Kamakura to experience this history.
