Kaifūsō 懷風藻 from the Nara period is the oldest surviving collection of Japanese kanshi 漢詩. Its poems were in a formative stage, imitating the poetry of the Six Dynasties and early Tang periods. However, after the middle and later Heian period, distinctly Japanese forms of kanshi such as the seven-character regulated verse and kudaishi句題詩 began to emerge amidst the popularity of Bai Juyi’s poetry. During the Kamakura period, the practitioners of kanshi starkly shifted from aristocrats to Zen monks, marking the beginning of what is called gozan bungaku 五山文學, which continued into the Muromachi period. During this time, the literature of the Song and Yuan dynasties—especially Su Shi and Huang Tingjian’s poetry from the Northern Song—was held in high regard, as well as the poetry of Du Fu, who greatly influenced them. Influenced by these three figures, Zen monks of the Muromachi period not only composed kanshi, but also gave lectures on their poetry and preserved their teachings in shōmono. These shōmono hold unique significance in the history of Japanese kanshi studies as the first interpretive works. This paper outlines the reception of Du Fu’s poetry up until the early era of Gozan Bungaku and then introduces four shōmono on Du Fu’s poetry from the middle period and beyond.
