Naruto World, Geographically Speaking.

[Tehshutur]

The Naruto world geographically mirrors that of Awaji-shima and Shikoku Island in Japan:

The Great Naruto Bridge in part 1 is based on the real life Naruto Bridge that connects the two islands.

Uzu no Kuni aka the Land of Whirlpools was based on the legendary island of Onogoro that was created with the divine naginata
Ame-non-uboko, from which the Sage's sword Nunoboko was directly inspired from. Onogoro Island is traditionally found in the Naruto Whirlpools, for when the divine couple Izanagi and Izanami dipped Ame-non-uboko into the water, its stirring formed the whirlpools and from this whirlpools rose Onogoroshima which became the new home of the creator spouse when they relocated from Heaven to Earth.​

Well then, thanks for that bit of knowledge Sir Derp Obito.
Now we know that everything is even smaller, all takes place on a giant island XD.

I have a headcanon about the "outside world" beyond NB borders. Basically ninja are isolated and they can't leave or even trade with the world outside due to governmental conspiracy, however there are still (illegal of course) smuggling operations, which is why they have pieces of technology but obviously no means of manufacturing them. Gato was one of such smugglers and his death was actually orchestrated by some evil higher-ups. Something like that
