In its economic relations, Japan is both a major trading nation and one of the largest international investors in the world. In many respects, international trade is the lifeblood of Japan's economy. Imports and exports totaling the equivalent of nearly US$1.309.2 Trillion in 2017, which meant that Japan was the world's fourth largest trading nation after China, the United States and Germany. Trade was once the primary form of Japan's international economic relationships, but in the 1980s its rapidly rising foreign investments added a new and increasingly important dimension, broadening the horizons of Japanese businesses and giving Japan new world prominence.
