Cultural Diversity Makes Okinawan Way

There are many studies on the history before the Ryukyu Kingdom was born in 1429, but the history of the Ryukyu Kingdom, which had a 450-year history as an independent country until it became Okinawa in 1879, unraveled the uniqueness of Okinawa. Through the trade relationships with China, Japan, Korea, and other Southeast Asian countries during the Ryukyu Kingdom era, Okinawa welcomed cultural exchanges, learned from them, maturing together. Those are the backbone that made Okinawa's culture unique and declared a UNESCO World Heritage Site.

The Ryukyu Kingdom prospered mainly around the southern part of Okinawa Main Island for 450 years from 1429 to 1879. Shō Hashi united the leaders from each region and became the first king of the Ryukyu Kingdom in 1429. Shurijo Castle (caution: before dawn on October 31, 2019, at least seven buildings, including the Seiden, an Okinawa landmark, burned down due to a fire) was the center of the kingdom, and as a maritime nation, the Ryukyu Kingdom deepened cultural exchanges and relationships with China, Japan, and other Asian countries. It is said that the port of Naha at that time was full of imported goods and foreigners and flourished as a base for East Asian trade. That was a time called the Great Trade Era and a Portuguese Tome Pires mentioned Ryukyu as “Lequio” in his book “The Suma Oriental,” and described how it rejoiced its prosperity.


In 1609, shortly after Japan started the Edo Shogunate, the Ryukyu Kingdom was invaded by the Satsuma Domain (present-day Kagoshima Prefecture) and the influence of Japan became stronger since then and it made Okinawa even foster its distinctive culture. Furthermore, when the Edo Shogunate was over and Japan opened the country and entered the Meiji era, the 450-year-old kingdom of Ryukyu also disappeared and became Okinawa Prefecture.

Okinawa has such a historical background, The “Gusuku Sites and Related Properties of the Kingdom of Ryukyu” is the icon of the culture of the Ryukyu and the UNESCO made a statement below:


Criterion (ii): For several centuries the Ryukyu islands served as a centre of economic and cultural interchange between south-east Asia, China, Korea, and Japan, and this is vividly demonstrated by the surviving monuments.


Criterion (iii): The culture of the Ryukyuan Kingdom evolved and flourished in a special political and economic environment, which gave its culture a unique quality.

Criterion (vi): The Ryukyu sacred sites constitute an exceptional example of an indigenous form of nature and ancestor worship that has survived intact into the modern age alongside other established world religions.


As Japan moved quickly to become a modern nation by fighting with the Western nations, Okinawa was involved and was tossed by international politics. In March 1945, when the Pacific War was about to end, the U.S. troops landed on Okinawa. A fierce ground battle, called the “Iron Storm,” took place, and the number of people who died reached about 240,000, including about 100,000 Okinawans. After the war, Okinawa was under the U.S. administration for 27 years and during that time, the military base was built, expanded, and still exists even Okinawa returned to Japan on May 15th, 1972.
