Title: Second Sino-Japanese War
Content:  In Japanese propaganda, the invasion of China became a crusade (聖戦), the first step of the "eight corners of the world under one roof" slogan (八紘一宇). In 1940, Japanese Prime Minister Fumimaro Konoe launched the Taisei Yokusankai. When both sides formally declared war in December 1941, the name was replaced by "Greater East Asia War" (大東亞戰爭). Although the Japanese government still uses the term "China Incident" in formal documents, the word Shina is considered derogatory by China and therefore the media in Japan often paraphrase with other expressions like "The Japan–China Incident" (日華事變/日支事變), which were used by media as early as the 1930s. The name "Second Sino-Japanese War" is not commonly used in Japan as the war it fought against China in 1894 to 1895 was led by the Qing dynasty, and thus is called the Qing-Japanese War (日清戦争), rather than the First Sino-Japanese War.

This name was released to the public on 12 December, with an explanation that it involved Asian nations achieving their independence from the Western powers through armed forces of the Greater East Asia Co-Prosperity Sphere. Japanese officials integrated what they called the Japan–China Incident (日支事変) into the Greater East Asia War. During the Allied military occupation of Japan (1945–52), these Japanese terms were prohibited in official documents, although their informal usage continued, and the war became officially known as the Pacific War (太平洋戦争). In Japan, the Fifteen Years' War (十五年戦争) is also used, referring to the period from the Mukden Incident of 1931 through 1945.
Title: Japanese war crimes
Content:   War crimes were committed by the Empire of Japan 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 an "Asian Holocaust", but this characterization of Japanese war crimes has been challenged by scholars on the basis of the unique features of the Holocaust. Some war crimes were committed by Japanese military personnel during the late 19th century, but most of them were committed during the first part of the Shōwa era, the name which was given to the reign of Emperor Hirohito. Under Emperor Hirohito, the Imperial Japanese Army (IJA) and the Imperial Japanese Navy 
Title: Definitions of Japanese war crimes
Content:  In Japan, the term "Japanese war crimes" generally refers to cases tried by the International Military Tribunal for the Far East, also known as the Tokyo Trials, following the end of the Pacific War. The tribunal did not prosecute war crimes allegations involving mid-ranking officers or more junior personnel. Those were dealt with separately in other cities throughout the Asia-Pacific region. The Japanese government said that Japan was not a signatory to the 1929 Geneva Convention on Prisoners of War, although it was the signatory of the 1907 Hague Convention, which provided humane treatment of prisoners of war (POWs), and the 1929 Geneva Convention on the Sick and Wounded Armed Forces in the Field, which provided humane treatment for enemy combatants who were injured, sick, or any other causes in the battlefield. It also signed the Kellogg-Briand Pact in 1929, thereby rendering 
Title: Pacific War
Content:  In Allied countries during the war, the "Pacific War" was not usually distinguished from World War II in general, or was known simply as the War against Japan. In the United States, the term Pacific Theater was widely used, although this was a misnomer in relation to the Allied campaign in Burma, the war in China and other activities within the South-East Asian Theater. However, the US Armed Forces considered the China-Burma-India Theater to be distinct from the Asiatic-Pacific Theater during the conflict. Japan used the name Greater East Asia War (大東亜戦争), as chosen by a cabinet decision on 10 December 1941, to refer to both the war with the Western 
Title: Second Sino-Japanese War
Content:   In China, the war is most commonly known as the "War of Resistance against Japanese Aggression", and shortened to the "Resistance against Japanese Aggression" or the "War of Resistance". It was also called the "Eight Years' War of Resistance", but in 2017 the Chinese Ministry of Education issued a directive stating that textbooks were to refer to the war as the "Fourteen Years' War of Resistance" , reflecting a focus on the broader conflict with Japan going back to 1931. It is also referred to as part of the "Global Anti-Fascist War", which is how World War II is perceived by the Chinese Communist Party (CCP) and the PRC government. In Japan, nowadays, the name "Japan–China War" (日中戦爭) is most commonly used because of its perceived objectivity. When the invasion of China proper began 
Title: List of Japanese political and military incidents
Content:  This is a list of Japanese political and military incidents, as classified by Japanese terminology in which incident was a euphemism applied during the beginning of history and through to the outbreak of the Pacific War.
Title: Japanese war crimes
Content:  Outside Japan, different societies use widely different timeframes in defining Japanese war crimes. For example, the annexation of Korea by Japan in 1910 was enforced by the Japanese military, and the Society of Yi Dynasty Korea was switched to the political system of the Empire of Japan. Thus, North and South Korea refer to "Japanese war crimes" as events occurring during the period of Korea under Japanese rule. By comparison, the Western Allies did not come into military conflict with Japan until 1941, and North Americans, Australians, South East Asians and Europeans may consider "Japanese war crimes" to be events that occurred in 1942–1945. See, for example: Craig Symonds, "War, Politics, and Grand Strategy in the Pacific, 1941–1945", 
Title: Victory disease
Content:  The origin of the term (戦勝病, in Japanese ) is associated with the Japanese advance in the Pacific Theater of World War II, where, after attacking Pearl Harbor in 1941, Japan won a series of nearly uninterrupted victories against the Allies in Southeast Asia and the Pacific. Much of Japan's arrogance is attributed to the performance of Admiral Matome Ugaki. From overriding decisions to ignoring the evolving conflict in the Pacific, Ugaki's tactics incited tension and doubt in other Japanese military personnel before the Midway operation. Although the Japanese had planned to establish a perimeter and go on the defensive, victories encouraged them to continue expanding to an extent that strained logistics and the navy. This culminated in the Battle of Midway in 1942, a catastrophic defeat of the Japanese navy. All four Japanese aircraft carriers involved were sunk, and the hitherto unstoppable Japanese advance was blunted.

Therefore, Rummel’s estimate of 6-million to 10-million dead between 1937 (the Rape of Nanjing) and 1945, may be roughly corollary to the time-frame of the Nazi Holocaust, but it falls far short of the actual numbers killed by the Japanese war machine. If you add, say, 2-million Koreans, 2-million Manchurians, Chinese, Russians, many East European Jews (both Sephardic and Ashkenazi), and others killed by Japan between 1895 and 1937 (conservative figures), the total of Japanese victims is more
