It takes 20.6× Japan to fill Australia.

Japan stretches across a long arc of the Pacific, but laid over Australia it's
modest: the continent is big enough to hold Japan about 21 times over.
The numbers
- Australia: 7,723,177 km²
- Japan: 374,167 km²
7,723,177 ÷ 374,167 = 20.6, so roughly 21 Japans fit inside Australia.
Why the count is honest
The ratio doesn't depend on the map — 21 is 21 everywhere. Both countries sit at
moderate latitudes, so Mercator treats them similarly and neither is wildly
inflated. What fools the eye is shape: Japan's islands sprawl across a lot of
ocean, making the country feel larger than its land actually is.
