Japan Maritime Self-Defense Force

The Japan Maritime Self-Defense Force (海上自衛隊, Kaijō Jieitai), or JMSDF, is the naval branch of the Japan Self-Defense Forces, tasked with the naval defense of Japan. It was formed following the dissolution of the Imperial Japanese Navy (IJN) after World War II. The JMSDF has a fleet of 154 ships and 346 aircraft. Its main tasks are to maintain control of the nation's sea lanes and to patrol territorial waters. It also participates in UN-led peacekeeping operations (PKOs) and Maritime Interdiction Operations (MIOs).

History

Origin

Japan has a long history of naval interaction with the Asian continent, involving the transportation of troops, starting at least with the beginning of the Kofun period in the 3rd century. Following the attempts at Mongol invasions of Japan by Kublai Khan in 1274 and 1281, Japanese wakō became very active in plundering the coast of the Chinese Empire.

Japan undertook major naval building efforts in the 16th century, during the Warring States period, when feudal rulers vying for supremacy built vast coastal navies of several hundred ships. Around that time, Japan may have developed one of the world's first ironclad warships, when Oda Nobunaga (a Japanese daimyo) had six iron-covered Oatakebune made in 1576.

Imperial Japanese Navy

The Imperial Japanese Navy (IJN; Kyūjitai: 大日本帝國海軍 Shinjitai: 大日本帝国海軍  Dai-Nippon Teikoku Kaigun  or 日本海軍 Nippon Kaigun, literally "Navy of the Greater Japanese Empire") was the navy of the Empire of Japan from 1868 until 1945, when it was dissolved following Japan's defeat and surrender in World War II. The Japan Maritime Self-Defense Force (JMSDF) was formed after the dissolution of the IJN.

The Japanese Navy was the third largest navy in the world by 1920, behind the Royal Navy and the United States Navy (USN). It was supported by the Imperial Japanese Navy Air Service for aircraft and airstrike operation from the fleet. It was the primary opponent of the Western Allies in the Pacific War.

The origins of the Imperial Japanese Navy go back to early interactions with nations on the Asian continent, beginning in the early medieval period and reaching a peak of activity during the 16th and 17th centuries at a time of cultural exchange with European powers during the Age of Discovery. After two centuries of stagnation during the country's ensuing seclusion policy under the shoguns of the Edo period, Japan's navy was comparatively backward when the country was forced open to trade by American intervention in 1854. This eventually led to the Meiji Restoration. Accompanying the re-ascendance of the Emperor came a period of frantic modernization and industrialization. The navy's history of successes, sometimes against much more powerful foes as in the Sino-Japanese war and the Russo-Japanese War, ended in almost complete annihilation during the concluding days of World War II, largely by the USN.

Empire of Japan

The Empire of Japan (大日本帝國, Dai Nippon Teikoku, literally "Greater Japanese Empire") was the historical Japanese nation-state that existed from the Meiji Restoration in 1868 to the enactment of the 1947 constitution of modern Japan.

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 and the establishment of a colonial empire. Economic and political turmoil in the 1920s led to the rise of militarism, eventually culminating in Japan's membership in the Axis alliance and the conquest of a large part of the Asia-Pacific region. At the height of its power in 1942, the Empire ruled over a land area spanning 7,400,000 square kilometres (2,857,000 sq mi), making it one of the largest maritime empires in history.

After several large-scale military successes during the Second Sino-Japanese War (1937–1945) and the Pacific War, the Empire also gained notoriety for its war crimes against the peoples it conquered. After suffering many defeats and following the Soviet Union's declaration of war against Japan and invasion of Manchuria, and the atomic bombings of Hiroshima and Nagasaki, however, the Empire surrendered to the Allies on August 15, 1945. A period of occupation by the Allies followed the surrender, and a new constitution was created with American involvement in 1947, officially dissolving the Empire. Occupation and reconstruction continued well into the 1950s, eventually forming the current nation-state whose full title is the "State of Japan" or simply rendered "Japan" in English.

World War II

World War II (WWII or WW2), also known as the Second World War, was a global war that lasted from 1939 to 1945, although related conflicts began earlier. It involved the vast majority of the world's nations—including all of the great powers—eventually forming two opposing military alliances: the Allies and the Axis. It was the most widespread war in history, and directly involved more than 100 million people from over 30 countries. In a state of "total war", the major participants threw their entire economic, industrial, and scientific capabilities behind the war effort, erasing the distinction between civilian and military resources. Marked by mass deaths of civilians, including the Holocaust (in which approximately 11 million people were killed) and the strategic bombing of industrial and population centres (in which approximately one million were killed, and which included the atomic bombings of Hiroshima and Nagasaki), it resulted in an estimated 50 million to 85 million fatalities. These made World War II the deadliest conflict in human history.
