The island nation of Japan, has always needed to import many of the raw materials that simply did not exist in any large quantities on its island. Manchuria was rich coal, iron ore and soil to grow food for Japan. It also gave Japan a border with Russia. This prevented any Russian interference in Manchuria. In 1931, Japan launched an invasion of Manchuria and left the League of Nations. By 1932, japan controlled all of Manchuria and used their conquest to further their needs for war and for products for their people. Once in control of Manchuria, they developed railroads, hydroelectric power, and built a sizable iron and steel industry. This increased Japan's power economically and militarily.
