Ryukyu Historiography Sources

From Maritime Ryukyu, 1050–1650, by Gregory Smits (University of Hawaii Press, 2018), Kindle pp. 13-15:

This book is an interdisciplinary, revisionist history of the Ryukyu islands between approximately 1050 and 1650 with occasional excursions into later years. The year 1050 marks the approximate beginning of the “Gusuku [castle walls] Period” in the Ryukyu islands, a time when power centers emerged. In 1650, Shō Shōken (1617–1675) published Reflections on Chūzan (Chūzan seikan), Ryukyu’s first official history. For reasons that will become clear, this event is a fitting end point for this study....

During most of the period covered in this book, Ryukyuans produced few domestic written documents. Chinese residing near the port of Naha handled the documentation connected with tribute trade, and Buddhist priests from Japan were available to assist with diplomatic correspondence. However, there is no evidence of the use of written documents to conduct government administration before the sixteenth century. Even as late as 1606, Xià Zǐyáng, a Chinese investiture envoy residing in Ryukyu, concluded that “literary culture is not widespread” even among the priests of the royal temple of Enkakuji, who were deeply respected as Ryukyu’s learned elite. Shō Shōken was among the first generation of Ryukyuan officials who could engage Chinese or Japanese literate society in a sophisticated manner.

What, therefore, were the sources Shō Shōken and later writers of official histories used? According to the introduction in Reflections, he interviewed elderly officials. Chinese records and written accounts by Japanese or Korean visitors provided some information, but for the most part, the details of early Ryukyu in the official histories are based on lore of unverifiable provenance. To some extent for sixteenth-century material, and more so from the seventeenth century onward, it is possible to corroborate accounts in the official histories using other sources. For material before the sixteenth century, however, such corroboration is rarely possible.

Ryukyu’s official histories share an ideological perspective. Steeped in Confucian historiography, they assume that a morally attuned universe guides the trajectory of human societies. Morally upright rulers bring tranquility, prosperity, dynastic longevity, and other desirable social characteristics. Strife, disorder, succession disputes, and dynastic turnover, by contrast, are evidence of rulers’ moral shortcomings. Founders of a ruling line were always virtuous. Conversely, the last ruler of a line could only have been morally deficient, not a victim of forces beyond his control. In addition, the official histories functioned to project an image of Ryukyu for outside consumption. In this context, they exaggerated the antiquity of a unified Okinawan state, positing its origins around 1200, approximately three centuries too early.

The official histories have created the dominant framework for early Ryukyuan history to this day. This book is an attempt to write a history of early Ryukyu from outside that framework. Instead of assuming that the official histories are probably accurate unless proven otherwise, I took the working hypothesis that material in the official histories before the sixteenth century is likely to be unreliable unless corroborated by other sources or evidence. Implicit in distancing myself from the official histories is the argument that it is possible to write a more nuanced and accurate history of early Ryukyu by looking elsewhere.

One important alternative source is Omoro sōshi, a collection of songs composed between approximately the twelfth and early seventeenth centuries. Other than diplomatic and trade documents and a few monument inscriptions, it contains the only native Ryukyuan source material predating the sixteenth century. Using Omoro sōshi as a historical source is not new. Iha Fuyū (1876–1947) did so, and in 1987 Mitsugu Sakihara published A Brief History of Early Okinawa Based on the Omoro Sōshi. Sakihara sought to combine “the traditional official records and histories” with the Omoro songs to create “a more accurate and vivid reconstruction.” In 2006 Yoshinari Naoki and Fuku Hiromi published a revisionist history of early Ryukyu based on a close reading of Omoro sōshi songs. They have expanded this initial effort in subsequent single- and dual-authored books.

To use Omoro sōshi effectively it is necessary to map the cultural geography reflected in its songs. While later chapters of this book rely on a mix of sources more typical of historical research, the early chapters are interdisciplinary. In them, I rely on published research in the fields of cultural anthropology and archaeology and supplement this material with conventional historical sources such as official Chinese and Korean records. Throughout the analysis, I engage Ryukyu’s official histories when appropriate, but I rarely rely on them. Moreover, I often arrive at different conclusions.
