Japan's Longest Day: Japan's Longest Day (日本のいちばん長い日 "Nihon no ichiban nagai hi"), also known as The Emperor and the General, is a 1967 movie directed by Kihachi Okamoto.  The subject of the majority of the movie is the period between noon on August 14, 1945, when Emperor Hirohito made the decision to surrender to the Allies in World War II and noon on August 15, 1945, when the emperor's taped message announcing the surrender was broadcast to the Japanese people.  Joseph L. Anderson describes the film as "a meticulous reconstruction of the day Japan surrendered and thus ended the Pacific War.  Several of Japan's most famous actors of the day participated in the film.  These included Chishū Ryū as Prime Minister Kantaro Suzuki, Toshirō Mifune as War Minister Korechika Anami, Takashi Shimura as Information Bureau Director Hiroshi Shimomura and Sō Yamamura as Navy Minister Mitsumasa Yonai.  Tatsuya Nakadai serves as the narrator.

Japanese dissidence during the early Shōwa period: Japanese dissidence during the early Shōwa period was dissidence by Japanese citizens of the Empire of Japan (1868–1947) during the Shōwa period, the reign of the Shōwa Emperor, Hirohito (1926–1989).  The early Shōwa period witnessed the rise of Japanese militarism, and Imperial Japan's full-scale invasion of China in the Second Sino-Japanese War (1937–1945), which escalated into a full-scale invasion of the Asia-Pacific during the Pacific theatre of World War II (1941–1945).  Throughout the period, there was political repression in Imperial Japan.

Victory in Europe Day: Victory in Europe Day, generally known as V-E Day, VE Day or simply V Day, was the public holiday celebrated on 8 May 1945 to mark the formal acceptance by the Allies of World War II of Nazi Germany's unconditional surrender of its armed forces.  It thus marked the end of World War II in Europe.

Surrender of Japan: The surrender of Imperial Japan was announced on August 15 and formally signed on September 2, 1945, bringing the hostilities of World War II to a close.  By the end of July 1945, the Imperial Japanese Navy (IJN) was incapable of conducting major operations and an Allied invasion of Japan was imminent.  Together with the British Empire and China, the United States called for the unconditional surrender of the Japanese armed forces in the Potsdam Declaration on July 26, 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 still-neutral Soviet Union to mediate peace on terms more favorable to the Japanese.  Meanwhile, the Soviets were preparing to attack Japanese forces in Manchuria and Korea (in addition to South Sakhalin and the Kuril Islands) in fulfillment of promises they had secretly made to the United States and the United Kingdom at the Tehran and Yalta Conferences.

Victory over Japan Day: Victory over Japan Day (also known as V-J Day, Victory in the Pacific Day, or V-P Day) is the day on which Imperial Japan surrendered in World War II, in effect ending the war.  The term has been applied to both of the days on which the initial announcement of Japan's surrender was made – to the afternoon of August 15, 1945, in Japan, and, because of time zone differences, to August 14, 1945 (when it was announced in the United States and the rest of the Americas and Eastern Pacific Islands) – as well as to September 2, 1945, when the signing of the surrender document occurred, officially ending World War II.

Japanese occupation of Hong Kong: The Imperial Japanese occupation of Hong Kong (香港日治時期) began when the Governor of Hong Kong, Sir Mark Young, surrendered the British Crown colony of Hong Kong to Imperial Japan on 25 December 1941.  The surrender occurred after 18 days of fierce fighting against the overwhelming Japanese forces that had invaded the territory.  The occupation lasted for three years and eight months until Japan surrendered at the end of Second World War.  The length of this period (三年零八個月) later became a metonym of the occupation.

Imperial Japanese Navy Technical Department: The Imperial Japanese Navy Technical Department (艦政本部 , kansei hombu , Short form: 艦本 "kampon") was the externally operating division of the Ministry of the Navy of Japan responsible for the administration of naval vessel construction.  From 1923 onward, it took on the role of a research institution for the research and development of naval technologies and engineering.  This included studying and investigating existing western naval technology, developing and overseeing Japan's domestic shipbuilding and arms industries, and training officers to become naval engineers and inspectors.  The bureau was dismantled along with the naval ministry in November 1945 after Japan surrendered to the Allies at the end of World War II.

United States in the Korean War: At the conclusion of World War II the Allied nations began the process of disarmament of Axis controlled regions.  Japan occupied Korea at this time and had been in control since 1910.  In 1945, the decision was made to have American Marines forces oversee Japanese surrender and disarmament south of the 38th parallel and the Soviet Union would facilitate the change of power to the north.  At the time there was no political motivation and seemed to be a logical and convenient plan of action.  The original agreement and intent was to create a unified and independent Korea out of the post Japanese occupation era.  Instead each side of the 38th parallel established its own government under the influence of the occupational country; the United States in South Korea and the Soviet Union in North Korea.  Both new Korean governments discredited the other and claimed to be the only legitimate political system.  Tensions between the North and South escalated and each side began to petition foreign powers for resources and support.  South Korea wanted weapons and supplies from Truman and the United States government while North Korea sought help from Stalin and the Soviet Union.  The United States was still war weary from the disruptive World War II campaign and refused South Korea's request for weapons and troops.  North Korea convinced the Soviet Union to supply them with the weapons and support they requested.  This decision coincided with the United States withdrawing the last remaining combat troops from South Korea.  North Korea saw its opportunity and attacked South Korean forces at the 38th parallel on June 25, 1950 and thus initiating the Korean War.
