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 Honshu
- Greenland (island), the largest of the 81 islands ranked on sizeversus, is 9.65× the size of Honshu; Honshu ranks 6th.
- Honshu sits between Baffin Island (509,000 km²) and Victoria Island (220,000 km²) in the ranking.
- Counted as a country, Honshu would be larger than 129 of the 212 countries listed on sizeversus and would rank 84th by area, between Laos (228,000 km²) and Guyana (211,000 km²).
- It is larger than 40 of the 51 US states and districts (the biggest of them is Minnesota, 225,000 km²) and smaller than 11.
- It is larger than 22 of the 31 provinces and regions of China (the biggest of them is Hunan, 211,000 km²) and smaller than 9.
- The closest US state is Minnesota (225,000 km²): Honshu is about the same size as Minnesota.
- On a standard web map (Web Mercator), a place at 37°N is drawn about 1.6× too large in area, so Honshu looks bigger there than it is.
- Laid out flat, Honshu stretches about 893 km north to south and 994 km east to west.
- Wikidata’s published figure of 228,000 km² agrees with our measured 225,000 km², to within 2%.

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

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.
