How big is Japan?
Japan encloses approximately 370,099 km² in this site’s Natural Earth boundary dataset. Japan’s outline is an archipelago, so its size is easier to understand through area than through the width of its bounding box. Compare it with the United Kingdom or Germany using the same calculation.

What the map shows
Japan sits at a lower representative latitude than the United Kingdom. Mercator changes the apparent area of each place by a different amount, even before either outline is moved. The equal-area view removes that area-scale difference.
The Mercator factor above is calculated at one representative point. It changes across the country and describes map enlargement, not a change in its real area. See Japan at its original position, then open the equal-area view.
Japan compared with United Kingdom
Japan is 1.54× the area of United Kingdom in this dataset. The bars below encode area as length, with the larger area spanning the full line.

What this area figure includes
At 1:50m resolution, small islands and intricate shorelines are simplified. The estimate measures the polygons represented by this source; it should not be treated as an inventory of every island’s surveyed area.
The area is calculated from the original Natural Earth 1:50m Admin 0 countries polygon. It is a consistent estimate for this map, not a certified land or total-area statistic. Read the area definitions before using the figure in research or teaching.
