 Nanzan was granted similar commercial status shortly afterwards, along with Hokuzan, but was restricted to sending only one ship per tribute mission.Over roughly the next thirty years, nineteen tribute missions were sent from Nanzan to China; Hokuzan sent nine and Chūzan sent fifty-two.Though these missions were meant to be limited to formal trade between the governments of Okinawa and China, it was not unknown for Nanzan officials, like those from the other two kingdoms, to engage in private trade and smuggling.
