Island of Okinawa
Okinawa Island is the largest of the Okinawa Islands in southern Japan, seat of the historic Ryukyu Kingdom that flourished as a maritime trading hub between China, Korea and Southeast Asia from the 15th century until Japanese annexation in 1879. The island’s extraordinary cultural heritage is embodied in its network of gusuku — distinctive Ryukyuan stone fortresses — nine of which form part of a UNESCO World Heritage ensemble inscribed in 2000, including Shuri Castle, the royal palace of the unified kingdom.

Overview
Okinawa Island measures roughly 106 kilometres long and 11 kilometres wide, covering approximately 1,207 square kilometres, with Naha as its prefectural capital. The island lies about 640 kilometres south of Kyushu and 500 kilometres east of Taiwan, a position that made it a crossroads of East Asian maritime commerce for centuries. Its humid subtropical climate, distinct Ryukyuan language traditions and UNESCO-listed gusuku ruins set it apart from mainland Japan as one of the country’s most layered cultural landscapes.
History
The island’s recorded political history begins with the Sanzan period (from 1314), when three competing kingdoms contested control; King Sho Hashi unified them in 1429 and established the Ryukyu Kingdom with its capital at Shuri Castle. In 1392, skilled migrants from China’s Fujian Province introduced technologies and diplomatic expertise that underpinned the kingdom’s golden age of sea trade. The Satsuma Domain of Japan invaded in 1609, forcing the Ryukyu rulers into dual tributary status serving both China and Japan until 1879, when the Meiji government formally annexed the archipelago.
What you see
The island’s most celebrated monument is Shuri Castle, a UNESCO World Heritage Site whose vermilion halls and ceremonial gates reconstruct the royal palace destroyed in 1945; the main courtyard buildings were damaged by fire in October 2019 and reconstruction is ongoing. Beyond Shuri, gusuku ruins dot the island’s hills — stone-walled enclosures that served as sacred places, residential compounds and administrative seats. Traditional craft traditions including Ryukyu bingata textile dyeing and lacquerware survive in Naha’s Tsuboya pottery district.
Cultural significance
Nine gusuku sites and related Ryukyu Kingdom properties were collectively inscribed on the UNESCO World Heritage List in 2000, recognising the island’s outstanding contribution to East Asian architectural and cultural history. Okinawa’s traditions represent a distinct civilisation that absorbed influences from China, Japan and Southeast Asia while developing its own language, music, performing arts and spiritual practices.
Practical information
Shuri Castle: 1-2 Kinjo-cho, Naha, Okinawa 903-0815. Open daily; hours and admission vary by reconstruction phase — check the official Shuri Castle website before visiting. The Okinawa Prefectural Museum and Art Museum offers additional context on Ryukyuan history and art.
Getting there
Naha Airport (OKA) receives direct flights from major Japanese cities and several international destinations including Taipei and Seoul. The Okinawa City Monorail (Yui Rail) connects Naha Airport to Shuri Station (approximately 30 minutes), a short walk from Shuri Castle. Rental cars are the most practical option for exploring gusuku sites beyond the capital.
