O Yun-gyeom was the leader selected by the Gwanghaegun of Joseon to head a mission to Japan in 1617.[2] The diplomatic mission functioned to the advantage of both the Japanese and the Koreans as a channel for developing a political foundation for trade.[3]
This delegation was explicitly identified by the Joseon court as a "Reply and Prisoner Repatriation Envoy" (회답겸쇄환사; 回答兼刷還使). The mission was not understood to signify that relations were "normalized."[4]
The Joseon monarch's ambassador and retinue traveled only as far as Kyoto, where the delegation was received by ShōgunHidetada at Fushimi Castle.[5]
