Ryukyuan sources indicate that ''ayabune'' were sent twice during the reign of King [[Sho Sei|Shô Sei]], three times during the reign of King [[Sho Ei|Shô Ei]] (r. [[1573]]-[[1589]]), and four times during the reign of King [[Sho Nei|Shô Nei]] (r. [[1589]]-[[1621]]). However, while such missions were sent on a variety of ceremonial occasions, they were typically not dispatched in recognition or celebration of Shimazu succession.<ref name=kuro/>

Shimazu documents emphasize that the ''ayabune'' stopped coming for a time in the late 16th century. [[Shimazu Takahisa]] died in [[1566]] and was succeeded as head of the family by [[Shimazu Yoshihisa]]; but according to Shimazu accounts, when the Shimazu informed Ryûkyû of this development in [[1570]], there was no response, and furthermore, when missions did resume in [[1573]], the [[Sanshikan]] are said to have showed contempt, or insulted, the members of the embassy. This was termed the "''ayabune'' failure of courtesy incident" (''ayabune ketsurei jiken''), and was cited among the pretexts for the Shimazu invasion of Ryûkyû in 1609.

Another mission was dispatched only three years later, but, even so, Ryûkyû is said to have become hesitant to send missions around this time, feeling that the threat of [[wako|piracy]] had grown stronger.<ref>Kuroshima, 23.</ref> When missions did resume in [[1573]], the [[Sanshikan]] are said to have showed contempt, or insulted, the members of the embassy.

Ships which brought [[tribute]] from Ryûkyû to Satsuma after the 1609 invasion were called ''[[kaisen]]''.
