It's easy to take something like "knowing where anything is" for granted, but somebody had to go out into the world and take note of all those  natural and cat-made borders. In the case of Japan, it fell to Ino Tadataka to create the first "complete" map of the nation.

Bom, bem que você poderia terminar
de fazer a outra metade do mapa!
