Second Sino-Japanese WarThe Second Sino-Japanese War was a military conflict primarily between the Republic of China and the Empire of Japan from 1937 to 1945, as part of World War II. In China, the war is called the War of Resistance against Japanese Aggression (). This total war between China and the Empire of Japan is often regarded as the beginning of World War II in Asia, although some scholars consider the European War and the Pacific War to be entirely separate, albeit concurrent.
Empire of JapanThe Empire of Japan or Japanese Empire, also referred to as Imperial Japan, was the Japanese nation-state that existed from the Meiji Restoration in 1868 until the enactment of the reformed Constitution of Japan in 1947. From 29 August 1910 until 2 September 1945, it administered the naichi (the Japanese archipelago and post-1943 Karafuto) and the gaichi (Korea, Taiwan, Kwantung Leased Territory, and pre-1943 Karafuto). The South Seas Mandate was a single Japanese dependent territory in the name of the League of Nations.
Pacific WarThe Pacific War, sometimes called the Asia–Pacific War, was the theater of World War II that was fought in eastern Asia, the Pacific Ocean, the Indian Ocean, and Oceania. It was geographically the largest theater of the war, including the vast Pacific Ocean theater, the South West Pacific theater, the Second Sino-Japanese War, and the Soviet–Japanese War. The Second Sino-Japanese War between the Empire of Japan and the Republic of China had been in progress since 7 July 1937, with hostilities dating back to 1931 with the Japanese invasion of Manchuria.
Attack on Pearl HarborThe attack on Pearl Harbor was a surprise military strike by the Imperial Japanese Navy Air Service upon the United States against the U.S. naval base at Pearl Harbor in Honolulu, Hawaii, just before 8:00a.m. (local time) on Sunday, December 7, 1941. The United States was a neutral country at the time; the attack led to its formal entry into World War II on the side of the Allies the next day. The Japanese military leadership referred to the attack as the Hawaii Operation and Operation AI, and as Operation Z during its planning.
Crimes against humanityCrimes against humanity are widespread or systemic criminal acts which are committed by or on behalf of a de facto authority, usually by or on behalf of a state, that grossly violate human rights. Unlike war crimes, crimes against humanity do not have to take place within the context of wars, and they apply to widespread practices rather than acts which are committed by individuals. Although crimes against humanity apply to acts which are committed by or on behalf of authorities, they do not need to be part of an official policy, and they only need to be tolerated by authorities.
Japanese war crimesThe Empire of Japan committed war crimes and crimes against humanity in many Asian-Pacific countries during the period of Japanese imperialism, primarily during the Second Sino-Japanese and Pacific Wars. These incidents have been described as "the Asian Holocaust". Some war crimes were committed by Japanese military personnel during the late 19th century, but most were committed during the first part of the Shōwa era, the name given to the reign of Emperor Hirohito.
Unit 731, short for Manshu Detachment 731 and also known as the Kamo Detachment and the Ishii Unit, was a covert biological and chemical warfare research and development unit of the Imperial Japanese Army that engaged in lethal human experimentation and biological weapons manufacturing during the Second Sino-Japanese War (1937–1945) and World War II. It killed an estimated 200,000 to 300,000 people. It was based in the Pingfang district of Harbin, the largest city in the Japanese puppet state of Manchukuo (now Northeast China, formerly named Manchuria) and had active branch offices throughout China and Southeast Asia.
Comfort womenComfort women or comfort girls were women and girls forced into sexual slavery by the Imperial Japanese Army in occupied countries and territories before and during World War II. The term "comfort women" is a translation of the Japanese ianfu (慰安婦), which literally means "comforting, consoling woman". During World War II, Japanese troops forced hundreds of thousands of women from Korea, the Philippines, Vietnam, China, and other countries into brothels where they were sexually enslaved and repeatedly raped.
HirohitoHirohito (29 April 1901 - 7 January 1989) was the 124th emperor of Japan, reigning from 1926 until his death in 1989. Hirohito and his wife, Nagako, had two sons and five daughters; he was succeeded by his fifth child and eldest son, Akihito. By 1979, Hirohito was the only monarch in the world with the title "Emperor". He was the longest-reigning historical Japanese emperor and one of the longest-reigning monarchs in the world. He was the head of state under the Meiji Constitution during Japan's imperial expansion, militarization, and involvement in World War II.
Historical negationismHistorical negationism, also called denialism, is falsification or distortion of the historical record. It should not be conflated with historical revisionism, a broader term that extends to newly evidenced, fairly reasoned academic reinterpretations of history. In attempting to revise the past, illegitimate historical revisionism may use techniques inadmissible in proper historical discourse, such as presenting known forged documents as genuine, inventing ingenious but implausible reasons for distrusting genuine documents, attributing conclusions to books and sources that report the opposite, manipulating statistical series to support the given point of view, and deliberately mistranslating texts.
