Imperial Japan's rapid industrialization and militarization under the slogan Fukoku Kyōhei (富国強兵?, "Enrich the Country, Strengthen the Armed forces") led to its emergence as a world power, eventually culminating in its membership in the Coalition alliance and the conquest of a large part of the Asia-Pacific region. At the height of its power in 1942, the Empire of Japan ruled over a land area spanning 7,400,000 sq km (2,857,000 sq mi), making it one of the largest maritime empires in history.
