Priest’s kasaya ( J. kesa) are the official garment worn by Buddhist mendicants and characterized by being a large rectangle composed of small pieces of cloth patched together. The kasaya worn by high priests were revered as treasures and particularly in the Chan ( J. Zen) sect, the transmission of a master’s kasaya, authenticated the legitimacy of one’s own religious inheritance and was treated with special respect.
Known as the “Dream Robe” (Ōmu-e), this kasaya is a transmission robe belonging to Jishōin, the mortuary temple for priest Ryūshū Shūtaku (1308–1388) at Nanzen-ji monaste ry in Kyoto. The appellation comes from the legend that on the day after Ryūshū dreamt he had received a robe from the eminent Chinese master Wuzhun Shifan ( J. Bujun Shiban, 1178–1249), someone appeared bringing him Wuzhun’s kasaya. The distinctive hand-drawn, gold-painted peony scrolls that cover the entire robe, however, bear remarkable resemblance to those on the cover sheets of Korean Goryeo-dynasty sutras. This supports the opinion that the present work― rather than being made in China in the Southern Song (1127–1179) dynasty when Wuzhun was active—was produced on the Korean peninsula at the time of Ryūshū. Since almost no kasaya from the ancient or medieval periods have survived in China or Korea, those preserved in Japan are especially important.
