It takes 25.3× Japan to fill United States of America.
Open in the sandbox The count
Japan packs more than 120 million people onto a chain of mountainous islands. The
United States — stretching from the Atlantic to the Pacific, plus Alaska and Hawaii —
is large enough to hold Japan about 25 times over.
The numbers
- United States: 9,468,993 km²
- Japan: 374,167 km²
9,468,993 ÷ 374,167 = 25.3, so roughly 25 Japans fit inside the USA.
Why the count is honest
The 25-to-1 ratio is true on any map — area doesn't depend on the projection. Both
countries sit mostly at middle latitudes, so Mercator treats them fairly similarly
and neither is wildly inflated. What fools the eye is Japan's shape: its long, narrow
arc of islands sprawls across a lot of ocean, making the country read as larger than
its land really is.
Try it
Hit Fill to full to stack Japan until the United States is full — about 25
bands, an island chain tiled across a continent. Add them one by one, or open in
