literature, especially on the literature from the Muromachi period and on scholars and poets in the Edo period, including Matsuo Bashō, the very greatest of all haiku poets. Even in modern Japanese, the term is mostly synonymous with Du Fu. Until the 13th century, the Japanese preferred Bai Juyi above all poets and there were few references to Du Fu, although his influence can be seen in some kanshi ("Chinese poetry made by Japanese poets") anthologies such as Bunka Shūreishū in the 9th century. The first notable Japanese appreciator of Du Fu's poetry was Kokan Shiren (1278–1346), a Rinzai Zen patriarch and one of the most prominent authors of the literature of the Five Mountains; he highly praised Du Fu and made a commentary on some poems of Du Fu from the perspective of a Zen priest in Vol. 11 of Saihokushū. His student Chūgan Engetsu composed many kanshi which were clearly stated to be "influenced by Du Fu" in their prefaces. Chūgan's student Gidō Shūshin had close connection with the Court and Ashikaga Shogunate and propagated Du Fu's poetry in the mundane world; one day Nijō Yoshimoto, the Kampaku regent of the Court and the highest authority of renga poetry, asked Gidō, "Should I learn the poetry of Du Fu and Li Bai?" Gidō dared to reply, "Yes if you do have enough capability. No if do not." Since then, there had been many seminars on Du Fu's poetry both in Zen temples and in the aristocratic society, and as a result his poetry was often cited in Japanese literature in the Muromachi period, e.g., Taiheiki, a historical epic in the late 14th century, and some noh plays such as Hyakuman, Bashō, and Shunkan. During the Kan'ei era of the Edo period (1624–1643), Shào Chuán () of the Ming Dynasty's was imported into Japan, and it gained explosive popularity in Confucian scholars and chōnin (townspeople) class. The commentary established Du Fu's fame as the highest of all poets; for instance, Hayashi Shunsai, a notable Confucian scholar, commented in Vol. 37 of Gahō Bunshū that Zǐměi [Du Fu] was the very best poet in history and praised Shào Chuán's commentary for its simplicity and readability, while he criticised old commentaries during the Yuan Dynasty as too unfathomable. Matsuo Bashō, the greatest haiku poet, was also strongly influenced by Du Fu; in Oku no Hosomichi, his masterpiece, he cites the first
