The number of Chinese killed by the Japanese during WW2 is greater than the number of Jews killed in the Holocaust.
War crimes were committed by the Empire of Japan in many Asia-Pacific countries during the period of Japanese imperialism, primarily during the Second Sino-Japanese War and World War II. These incidents have been described as an "Asian Holocaust". Some war crimes were committed by Japanese military personnel during the late 19th century, but most Japanese war crimes were committed during the first part of the Showa Era, the name given to the reign of Emperor Hirohito until the surrender of the Empire of Japan in 1945.
The war crimes involved the Imperial Japanese Army and the Imperial Japanese Navy under Emperor Hirohito and were responsible for the deaths of millions. Historical estimates of the number of deaths which resulted from Japanese war crimes range from 3 to 14 million through massacre, human experimentation, starvation, and forced labor that was either directly perpetrated or condoned by the Japanese military and government.
