Though Ryûkyû often sent diplomatic messages in the official ''zi'' (咨) format used by [[Ming Dynasty]] China, Joseon preferred the "private letter" format known as ''[[shokei]]'' in Japanese (書契, K: ''sogye'').

A [[kango boeki|tally]]-like system in which a half-cut [[seals|seal]] was used was introduced at the recommendation of [[Hakata]] merchant [[Taira no Nobushige]] in [[1471]], and used for a time from then on in Korea-Ryûkyû relations.

Ryukyuan relations with Korea were typified by the use of Japanese merchants or monks as leaders of missions to Korea, and by the not infrequent occurrence of imposter envoys from Hakata, especially in the 1470s-90s, and declining significantly after that. Nobushige himself is believed to have been an imposter envoy, as documents from the previous year (1470) indicate a [[Taira no Yoshishige]] being designated the official envoy.

After 1527, direct relations with Korea came to an end, and until 1638, relations with Korea were handled only indirectly, via Beijing. From 1638 to 1891, Ryûkyû's relations with Korea were largely limited to the exchange of castaways.<ref>Schottenhammer, Angela.
