KantokuenKantokuen (関特演, from 関東軍特種演習, Kantōgun Tokushu Enshū, "Kwantung Army Special Maneuvers") was an operational plan created by the General Staff of the Imperial Japanese Army for an invasion and occupation of the Russian Far East, capitalizing on the outbreak of the Soviet-German War in June 1941. Involving seven Japanese armies and a major portion of the empire's naval and air forces, it would have been the largest combined arms operation in Japanese history up to that point, and one of the largest of all time.
Co-belligerenceCo-belligerence is the waging of a war in cooperation against a common enemy with or without a formal treaty of military alliance. Generally, the term is used for cases where no alliance exists. Likewise, allies may not become co-belligerents in a war if a casus foederis invoking the alliance has not arisen. Co-belligerents are defined in the Encyclopaedic Dictionary of International Law as "states engaged in a conflict with a common enemy, whether in alliance with each other or not".
Hokushin-ron北進論 was a political doctrine of the Empire of Japan before World War II that stated that Manchuria and Siberia were Japan's sphere of interest and that the potential value to Japan for economic and territorial expansion in those areas was greater than elsewhere. Its supporters were sometimes called the Strike North Group. It enjoyed wide support within the Imperial Japanese Army during the interwar period but was abandoned in 1939 after military defeat on the Mongolian front at the Battles of Khalkhin Gol (known in Japan as the Nomonhan incident) and the signing of Soviet–Japanese Neutrality Pact in 1941.

Non-aggression pactA non-aggression pact or neutrality pact is a treaty between two or more states/countries that includes a promise by the signatories not to engage in military action against each other. Such treaties may be described by other names, such as a treaty of friendship or non-belligerency, etc. Leeds, Ritter, Mitchell, & Long (2002) distinguish between a non-aggression pact and a neutrality pact.
Nanjing MassacreThe Nanjing Massacre (, Nankin Daigyakusatsu) or the Rape of Nanjing (formerly romanized as Nanking) was the mass murder of Chinese civilians in Nanjing, the capital of the Republic of China, immediately after the Battle of Nanking in the Second Sino-Japanese War, by the Imperial Japanese Army. Beginning on December 13, 1937, the massacre lasted six weeks. The perpetrators also committed other war crimes such as mass rape, looting, and arson. The massacre is considered to be one of the worst wartime atrocities.
