Economy/Geography- Above is an image of Japan, shown on a map. Japan is a chain of islands, and archipelago. But this does introduce some problems. One of these is that there is barely any land for living on. Only 11.65% of Japan is covered in arable land, a very low percentage. Also, because of its mountains, it doesn't have very good farming land which hurts its economy. That also means Japan imports 60% of its food, because there are barely any sources of food in Japan.
