How to read it
One and a half Singapores of land, under a quarter of the people.
Geography and shape
Okinawa Island is the largest island of Okinawa Prefecture, a long, narrow island between Kyushu and Taiwan. Singapore is a city-state on one main island and some sixty smaller islands at the southern tip of the Malay Peninsula.
Population context
Okinawa Island has 1,352,975 people on 1,208 km², about 1,120 per km². Singapore has 6,111,175 on 744 km², about 8,211 per km². Singapore holds about 4.5 times the island’s population on about 62% of its land.
Boundaries and definitions
Okinawa Island is the main island only, not the prefecture; the whole prefecture is 2,282 km² with 1,467,065 people. Singapore uses its total land area at 31 December 2025, which grows with reclamation, and its total population at end-June 2025, including about 1.91 million non-residents.
Okinawa Main Island: The main island of Okinawa, not the whole prefecture. Area is the island's own coastline, so bridge-connected satellites such as Yagaji, Henza and Sesoko are counted separately by the mapping authority. The prefectural population survey does the opposite: it reports only islands not linked by bridge, so those satellites are folded into this figure. The density shown is therefore about 2% high; a like-for-like denominator would be roughly 1,237 km². The count is the resident register, which includes foreign residents but not US military personnel stationed on the island.
Singapore: Total land area surveyed by the Singapore Land Authority as at 31 December 2025, covering the main island and its offshore islands. The figure rises with reclamation and is restated annually — it was 735.7 km² a year earlier. Population is the Department of Statistics total population at end-June 2025: citizens 3,660,683, permanent residents 543,832 and about 1.91 million non-residents, counted by place of usual residence, so tourists and short-term visitors are excluded. The two dates are six months apart, and the outline traces the main island, Pulau Ujong, which is about 88% of the official area — Pulau Tekong, Jurong Island, Pulau Ubin, Sentosa and some sixty smaller islands are counted in the figure but not drawn.
In-depth guide
How should Okinawa Main Island and Singapore be understood in context?
Okinawa and Singapore are both islands that many Asian travellers know, and the first surprise is that Okinawa Island is the larger — about one and a half Singapores — while Singapore has more than four times its people.
Bigger island, a quarter of the people
Okinawa Island’s 1,208 km² is about 1.6 times Singapore’s 744 km², while its 1.35 million people are about 22% of Singapore’s 6.11 million. The island averages about 1,120 people per km²; Singapore about 8,211.
Taking the whole prefecture — the Okinawa, Miyako and Yaeyama island groups — the land rises to 2,282 km², about 3.1 Singapores, with only about 114,000 more people.
