When Ryukyu Became a State

From Maritime Ryukyu, 1050–1650, by Gregory Smits (University of Hawaii Press, 2018), Kindle pp. 130-133:

Ryukyu became a formal state in the East Asian international order because of Ming policy to tame the region’s wakō and the related Maritime Prohibitions. When Yáng Zài traveled to Naha in 1372, Okinawa was an island governed by dozens of local lords. Although many or all of them engaged in private trade, none of them would have been capable of conducting formal tribute trade on their own. The lord of Urasoe became “king” for tribute purposes. Satto, the kings who followed him, and the kings associated with the northern and southern principalities, profited from the situation. Ryukyuan ships began sailing to Southeast Asia, typically via Fuzhou, but they did so in Chinese-made ships with Chinese captains guided by Chinese pilots and supported by Chinese interpreters. Similarly, as we have seen, Ryukyuan ships sailing to Korea were typically Japanese vessels commanded and piloted by Japanese or by mariners of mixed Korean and Japanese origins. Ships sailed to destinations in China, Southeast Asia, and Korea under the auspices of a Ryukyuan king, and Naha served as an international port. Ryukyuans were actively involved in this maritime activity, but the common image of Ryukyuan mariners independently sailing to a variety of far-flung kingdoms requires some modification. In many respects, during the late fourteenth century and well into the fifteenth, “Ryukyu” functioned much like a shipping company. Its two largest clients were the Ming court supported by Chinese living in Naha and the Ashikaga shoguns aided by Sakai [Osaka] merchants.

Citing research by Akamine Seiki demonstrating that Ryukyu did not conduct independent trade with Southeast Asia, a hypothesis by Ōta Ryōhaku that Chinese merchants in Naha constituted a shadow government that held the real power in early Ryukyu, and the relatively inferior quality of native Ryukyuan ships, Irei Takashi lamented that the image of Ryukyu’s “golden age” as a prosperous, independent maritime kingdom appears to be an illusion. In light of Ryukyu’s early modern and modern history of having been controlled by outside powers, Irei concludes, “That the ‘golden age’ was a falsehood is indeed a gloomy matter, but thinking about the storms of outside pressure that have scoured this cluster of islands, it is something we must accept.” Irei’s essay addresses the emotive impact for many contemporary people of the idealized image of early Ryukyu.

Early Ryukyu was not an illusion, but its history was more complex than ... the official histories, or many modern accounts acknowledge. One point to underscore is that although early Ryukyu was never formally part of any other country, it was not a de facto country itself until well into the reign of Shō Shin. Early Ryukyu was a frontier region within the East China Sea network generally and Japan in particular. Until the sixteenth century, there was no Okinawa-wide or Ryukyu-wide government, little or no literary culture outside of a few Buddhist temples, and there was a high level of internecine violence. Ryukyu did eventually become a centralized state and a far-flung empire. Moreover, from roughly 1510 to 1550, this Ryukyu empire enjoyed significant power and wealth. We could reasonably call this period a “golden” age, although it was fairly short and was more golden for some Ryukyuans than for others.
