Okinawa is Japan's southernmost prefecture, an archipelago of over 160 islands scattered across the East China Sea with a subtropical climate and unique Ryukyuan cultural heritage. Known for its crystal-clear turquoise waters, white sand beaches, and ancient castle ruins, Okinawa offers a distinctly different experience from mainland Japan. The islands are also celebrated worldwide for the extraordinary longevity of their residents and a laid-back lifestyle shaped by centuries of trade and cultural exchange.
Historical timeline
Key moments that shaped Okinawa.
-
1
Sanzan (Three Mountains) era
The Ryukyu Islands were divided among three rival kingdoms — Hokuzan (north), Chuzan (center), and Nanzan (south) — each building gusuku stone fortresses as seats of power and competing for control of maritime trade routes.
-
2
Unification of the Ryukyu Kingdom
Sho Hashi, king of Chuzan, conquered Hokuzan and Nanzan to unify the Ryukyu Islands under the First Sho Dynasty, establishing Shuri Castle as the royal capital and beginning the kingdom's golden age of maritime trade.
-
3
Ryukyu Kingdom maritime trade era
The unified kingdom became a major East Asian trading hub, conducting tributary trade with Ming and Qing China while trading silk, porcelain, and spices with Japan, Korea, and Southeast Asia. Ryukyuan performing arts, lacquerware, and textile crafts flourished under royal patronage.
-
4
Satsuma Domain conquers the Ryukyu Kingdom
Roughly 3,000 soldiers from Japan's Satsuma Domain (present-day Kagoshima Prefecture) invaded and subdued the Ryukyu Kingdom, which then paid tribute to Satsuma while formally maintaining its separate tributary relationship with China for over 250 years.
-
5
Ryukyu Shobun — abolition of the Ryukyu Kingdom
The Meiji government forcibly abolished the Ryukyu Kingdom, exiled the last king Sho Tai to Tokyo, and established Okinawa Prefecture. Japanization policies subsequently discouraged the Okinawan language and traditional dress.
-
6
Battle of Okinawa
An 82-day battle (April 1 - June 23, 1945) between US and Japanese forces killed an estimated 200,000 people, including roughly a quarter of Okinawa's civilian population, making it the bloodiest ground battle of the Pacific War.
-
7
Okinawa under US military government
Okinawa remained under US administration even after mainland Japan regained sovereignty in 1952. Extensive US military base construction displaced many Okinawan families, and the US dollar circulated as the local currency.
-
8
Okinawa reverts to Japanese sovereignty
On May 15, 1972, Okinawa was returned to Japanese administration following years of local protest. US military bases remained and today still occupy about 15% of the main island, a continuing point of political contention.
