Kanmon Railway Tunnel
The was the first undersea tunnel in Japan. It goes underneath the Kanmon Straits, connecting the islands of Honshu and Kyushu. It is an important link in the Japanese rail network. Its construction began in 1936, and it was completed in November 1942, during the Pacific War. The Honshu-bound tunnel is long, the Kyushu-bound tunnel is . Track gauge is (Cape gauge), and its electric power supply is at 1,500 volts DC. Near the end of the Pacific War the Allies planned to blow up the two tunnels with 50,000 pounds of explosives as part of the invasion of Japan. The Office of Strategic Services trained 250 of its agents for the task, but the surrender of Japan occurred before they were needed. The Kyushu Railway Company (JR Kyushu) assumed ownership of this tunnel following the breakup of the Japanese National Railways system in 1987.

Allies Of World War II
The Allies, formally referred to as the United Nations from 1942, were an international military coalition formed during the Second World War (1939–1945) to oppose the Axis powers, led by Nazi Germany, Imperial Japan, and Fascist Italy. Its principal members by 1941 were the United Kingdom, United States, Soviet Union, and China. Membership in the Allies varied during the course of the war. When the conflict broke out on 1 September 1939, the Allied coalition consisted of the United Kingdom, France, and Poland, as well as their respective dependencies, such as British India. They were soon joined by the independent dominions of the British Commonwealth: Canada, Australia, New Zealand and South Africa. Consequently, the initial alliance resembled that of the First World War. As Axis forces began invading northern Europe and the Balkans, the Allies added the Netherlands, Belgium, Norway, Greece, and Yugoslavia. The Soviet Union, which initially had a nonaggression pa ...

Railway Tunnels In Japan
Rail transport (also known as train transport) is a means of transport that transfers passengers and goods on wheeled vehicles running on rails, which are incorporated in tracks. In contrast to road transport, where the vehicles run on a prepared flat surface, rail vehicles (rolling stock) are directionally guided by the tracks on which they run. Tracks usually consist of steel rails, installed on sleepers (ties) set in ballast, on which the rolling stock, usually fitted with metal wheels, moves. Other variations are also possible, such as "slab track", in which the rails are fastened to a concrete foundation resting on a prepared subsurface. Rolling stock in a rail transport system generally encounters lower frictional resistance than rubber-tyred road vehicles, so passenger and freight cars (carriages and wagons) can be coupled into longer trains. The operation is carried out by a railway company, providing transport between train stations or freight customer faciliti ...

Shimonoseki
is a city located in Yamaguchi Prefecture, Japan. With a population of 265,684, it is the largest city in Yamaguchi Prefecture and the fifth-largest city in the Chūgoku region. It is located at the southwestern tip of Honshu facing the Tsushima Strait at the entrance to the Kanmon Straits (also known as the Straits of Shimonoseki) across from the city of Kitakyushu and the island of Kyushu. It is nicknamed the " Fugu Capital" for the locally caught pufferfish, and is the largest harvester of the pufferfish in Japan. History The geographical position of Shimonoseki has given it historical importance. The Heike and Genji fought at Dan-no-ura near the present Kanmon Bridge. In February 1691, German explorer Engelbert Kaempfer visited the town as part of his two-year stay in Japan, and described it as having around 400 to 500 houses, and as a major port in the region for supplying ship provisions. The Bombardment of Shimonoseki occurred in 1864, and the Treaty of Shimonoseki wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Surrender Of Japan
The surrender of the Empire of Japan in World War II was announced by Emperor Hirohito on 15 August and formally signed on 2 September 1945, bringing the war's hostilities to a close. By the end of July 1945, the Imperial Japanese Navy (IJN) had become incapable of conducting major operations and an Allied invasion of Japan was imminent. Together with the United Kingdom and China, the United States called for the unconditional surrender of the Japanese armed forces in the Potsdam Declaration on 26 July 1945—the alternative being "prompt and utter destruction". While publicly stating their intent to fight on to the bitter end, Japan's leaders (the Supreme Council for the Direction of the War, also known as the "Big Six") were privately making entreaties to the publicly neutral Soviet Union to mediate peace on terms more favorable to the Japanese. While maintaining a sufficient level of diplomatic engagement with the Japanese to give them the impression they might be wi ...

Office Of Strategic Services
The Office of Strategic Services (OSS) was the intelligence agency of the United States during World War II. The OSS was formed as an agency of the Joint Chiefs of Staff (JCS) to coordinate espionage activities behind enemy lines for all branches of the United States Armed Forces. Other OSS functions included the use of propaganda, subversion, and post-war planning. The OSS was dissolved a month after the end of the war. Intelligence tasks were shortly later resumed and carried over by its successors the Department of State's Bureau of Intelligence and Research (INR), and the independent Central Intelligence Agency (CIA). On December 14, 2016, the organization was collectively honored with a Congressional Gold Medal. Origin Prior to the formation of the OSS, the various departments of the executive branch, including the State, Treasury, Navy, and War Departments conducted American intelligence activities on an ''ad hoc'' basis, with no overall direction, coordination, or ...

Operation Downfall
Operation Downfall was the proposed Allied plan for the invasion of the Japanese home islands near the end of World War II. The planned operation was canceled when Japan surrendered following the atomic bombings of Hiroshima and Nagasaki, the Soviet declaration of war, and the invasion of Manchuria. The operation had two parts: Operation Olympic and Operation Coronet. Set to begin in November 1945, Operation Olympic was intended to capture the southern third of the southernmost main Japanese island, Kyūshū, with the recently captured island of Okinawa to be used as a staging area. In early 1946 would come Operation Coronet, the planned invasion of the Kantō Plain, near Tokyo, on the main Japanese island of Honshu. Airbases on Kyūshū captured in Operation Olympic would allow land-based air support for Operation Coronet. If Downfall had taken place, it would have been the largest amphibious operation in history, surpassing D-Day. Japan's geography made this invasion pl ...

Direct Current
Direct current (DC) is one-directional flow of electric charge. An electrochemical cell is a prime example of DC power. Direct current may flow through a conductor such as a wire, but can also flow through semiconductors, insulators, or even through a vacuum as in electron or ion beams. The electric current flows in a constant direction, distinguishing it from alternating current (AC). A term formerly used for this type of current was galvanic current. The abbreviations ''AC'' and ''DC'' are often used to mean simply ''alternating'' and ''direct'', as when they modify ''current'' or ''voltage''. Direct current may be converted from an alternating current supply by use of a rectifier, which contains electronic elements (usually) or electromechanical elements (historically) that allow current to flow only in one direction. Direct current may be converted into alternating current via an inverter. Direct current has many uses, from the charging of batteries to large power sup ...
