Buddhism in the Ryukyus

From Maritime Ryukyu, 1050–1650, by Gregory Smits (University of Hawaii Press, 2018), Kindle pp. 326-328:

Ryukyu’s temples were either Shingon or Rinzai Zen. Until approximately the sixteenth century, all or most of their abbots and priests came from Japan. During Shō Shin’s reign, native Ryukyuan priests became increasingly common, although the leadership posts in large temples typically remained in the hands of priests from Japan. As part of their training, Ryukyuan priests often resided in Japan. Therefore, Buddhist temples constituted an important network linking Ryukyu with Japan. Geographically, the most important of these priest-mediated connections to locations in Japan were Kagoshima, Suō Province in western Honshu (the domain of the Ōuchi), and especially the Kyoto Gozan temples.

Buddhist priests served as Ryukyu’s diplomats to powers in Japan, and they typically drafted and transmitted diplomatic correspondence. Because well-trained Buddhist priests could write classical Chinese, they were also in a position to facilitate trade and diplomacy with China. When in 1525 Ryukyu intervened to reduce tensions between Japan and China, priests served as the envoys. During the sixteenth century, priests performed many of the functions that resident Chinese had performed in the previous century. Recall that the population of Kumemura declined significantly during the sixteenth century.

Priests with diplomatic experience sometimes served as foreign-policy or general political advisers. For example, it is likely that the Ryukyuan Rinzai priest Kakuō (dates unknown) of Tenkaiji served as a political adviser to Shō Sei circa the 1530s. We have seen that the Satsuma Rinzai priest Nanpo Bunshi was an influential political adviser and diplomat during the years leading up to the 1609 war. When that war broke out, the king called on the Ryukyuan priest Kikuin (d. 1620) to serve as lead negotiator, in part because he had lived in Satsuma and was on good terms with Bunshi and several leaders of the invading force. Trusted by both Satsuma and the king, Kikuin served as Ryukyu’s prime minster (kokusō) until 1616.

Buddhist temples functioned as academic centers that could provide knowledge and know-how to Ryukyuan rulers. Priests were involved in culture, scholarship, and essential functions of state. Their activities included inscribing Shō Taikyū’s bells, creating the Omoro sōshi by writing down the songs, inscribing many of the monuments of Shō Shin and his successors, and drafting letters from the king to send to powers in Japan. During the sixteenth century, Buddhist priests served as tutors to elite Ryukyuans, Kaiin being the outstanding example (chapter 8). Moreover, we have seen that Enkakuji played a role in the education of the sons of elite families in Amami-Ōshima, and it likely functioned similarly vis-à-vis other islands.

Although Buddhism, Chinese thought, and native religion often occupied separate textual, rhetorical, and ritual realms, Shō Shin and his successors combined all three into a potent synthesis to enhance royal authority and defend the state. Some priests undoubtedly pursued Buddhist enlightenment through their own study and practice. Nevertheless, Buddhism in Ryukyu functioned mainly as a public state institution, not as a private spiritual path.
