The area is measured from the outline drawn above, on the WGS84 ellipsoid; the published figure is shown beside it, and a water body is kept only if the two are within 10%.
What the numbers say about Hokkaidō
- Greenland (island), the largest of the 81 islands ranked on sizeversus, is 28.2× the size of Hokkaidō; Hokkaidō ranks 20th.
- Hokkaidō sits between Ireland (island) (81,600 km²) and Sakhalin (74,500 km²) in the ranking.
- Counted as a country, Hokkaidō would be larger than 95 of the 212 countries listed on sizeversus and would rank 118th by area, between Serbia (77,600 km²) and Panama (74,500 km²).
- It is larger than 11 of the 51 US states and districts (the biggest of them is West Virginia, 62,700 km²) and smaller than 40.
- It is larger than 5 of the 31 provinces and regions of China (the biggest of them is Ningxia, 52,100 km²) and smaller than 26.
- The closest US state is South Carolina (80,200 km²): Hokkaidō is 96% of the size of South Carolina.
- On a standard web map (Web Mercator), a place at 43°N is drawn about 1.9× too large in area, so Hokkaidō looks bigger there than it is.
- Laid out flat, Hokkaidō stretches about 452 km north to south and 488 km east to west.
- Wikidata’s published figure of 78,000 km² agrees with our measured 77,100 km², to within 2%.

Where it lies
Natural Earth’s outlines of Japan contain or lie within 4 km of the outline of Hokkaidō. That is what its geometry says, and it is not a statement about who owns the water or where any border runs in it.

Sources and method
- Outline
- Natural Earth, 1:10m Geography Regions (geography_regions_polys), public domain (Geography Regions (geography_regions_polys)). Outlines of lakes are drawn at 1:10 million.
- Boundary
- A lake or a sea has no legal boundary of its own. The outline is a cartographic one, and the page says so by showing the measured area beside the published one.
- Area basis
- Measured outline: computed on the WGS84 ellipsoid from the full-detail outline and shown rounded. Published figure: Wikidata (CC0), fetched 2026-11-11. An outline is kept within 10% of the published figure and matched to other places automatically within 5%.
- Shore
- Countries whose Natural Earth outline contains or comes close to the water's outline; computed, not a statement of ownership.
- Drawing
- Each outline is projected with an equal-area projection centred on its own centroid, so areas stay true and two can be laid over each other.
