On a familiar scale

Okinawa Main Island ≈ 1.12 × Changhua County (reference rung) 893 m² of land per resident
Hong Kong ≈ the size of Changhua County (reference rung) 148 m² of land per resident

Reference scales come from Department of Household Registration, Ministry of the Interior: Land area, households and population density by township and district (year-end 2025) , as of 2025-12-31.

How to read it

Nearly the same land, a sixfold density gap: the same area holds about 1.35 million people in Okinawa and about 7.5 million in Hong Kong.

Geography and shape

Okinawa Main Island is a single long island; Hong Kong is a peninsula plus more than 200 islands at the mouth of the Pearl River. Both are hilly, and in both, a large share of the land is not built on — forest in northern Okinawa, country parks in Hong Kong.

Population context

Okinawa Main Island has about 1.35 million residents on 1,208 km², about 1,120 per km². Hong Kong has about 7.53 million on 1,114.57 km², about 6,760 per km².

Boundaries and definitions

Okinawa is the main island only, not Okinawa Prefecture; its population includes bridge-connected islets that its area leaves out, so its density reads about 2% high. Hong Kong uses its year-end 2024 population and total land area.

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.

In-depth guide

How should Okinawa Main Island and Hong Kong be understood in context?

Okinawa Main Island and Hong Kong are almost exactly the same size — Okinawa is about 8% larger. What separates them is people: Hong Kong fits about 5.6 times as many residents onto slightly less land.

Same size, different lives

Hong Kong averages about 6,760 people per km², Okinawa Main Island about 1,120. Both leave much of their land unbuilt — Hong Kong protects large areas as country parks, and northern Okinawa is mostly forest — so the difference is how tightly each packs its built-up land.

This makes the pair a useful mental map: if you know Hong Kong, Okinawa Main Island is the same footprint with a sixth of the density.
