4. Japan
We are continuing our list of greatest countries in the world with Japan, which is a worldwide leader in transportation and technology development. Samurai swords, temples and of course sushi, are all part of this country’s tradition, even though you may experience troubles holding the chopsticks. With the GDP of $4,939,384 million, the powerful military with a Power Index of 0.2137 and a population of 127.4 million people, this country definitely deserves to be this high on our list.
