Korean envoys were sent on 12 occasions to the Tokugawa administration during the Edo period. Today, They are considered as a model of "good neighborly friendship". However, the written transcripts between these people do not give this image. Hayashi Razan had relations with the first Korean Envoy until the 6th Korean envoy. In this paper, through the transcripts betweem Hayashi Razan and the Korean envoys, I hope to establish what images they had of eadh other before and after their meetings.
