Japan is one of the most powerful countries in the world, both economically and militarily. Its armed forces boast an active manpower of 240,000 troops and more than 1,000 combat tanks. Japan is also among the most technologically advanced countries in the world, and that has allowed its defense industry to grow at home as well and to become a major supplier of the Japanese military. In April this year, Tokyo announced signing a $2.8 billion deal with Mitsubishi Heavy Industries to develop long-range missiles.
