After reading a poem composed by a Palhae envoy in 815, a renowned Japanese poet said that he could hardly take his hand off the poem and was happy to recite it. Miyakono Yoshika, who boasted of being a good writer in Japan, lavished his praises on Yang Song Gyu, a Palhae envoy, after reading his writings in 872.

Various collections of prose and poetry and individual libraries which remain still in Japan reflect the conceits of Palhae envoys and laudation over them.

During the Imjin Patriotic War against Japan, the invaders kidnapped many Korean ceramists to Japan.

In the period of Ri Dynasty Korean messenger parties dispatched to Japan included many talented persons who were versed into calligraphy, painting and other cultural and artistic fields.
