1. Japan is an island nation – and then some!
Japan isn’t just one island — it’s an epic archipelago made up of 6,852 islands! The four main islands (Honshu, Hokkaido, Kyushu, and Shikoku) make up the majority of the country’s landmass, but the remaining thousands are scattered like emeralds across the Pacific.

Of those thousands of islands, only around 430 are inhabited, making Japan one of the few countries where untouched nature thrives alongside futuristic cities.
3. Japan has some interesting neighbours.
Situated in East Asia, Japan is close to countries like South Korea, China, Taiwan, Russia, and further south, the Philippines and Papua New Guinea – giving it a strategic cultural and economic position in the region.

From the snowy slopes of Hokkaido to the subtropical beaches of Okinawa, Japan offers everything from icy winters to humid summers. But across most of the country, temperatures tend to stay above freezing year-round.
