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 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 Shōwa Era, the name which was given to the reign of Emperor Hirohito.

War crimes in Manchukuo were committed during the rule of the Empire of Japan in northeast China, either directly, or through its puppet state of Manchukuo, from 1931 to 1945. Various war crimes have been alleged, but have received comparatively little historical attention.

The Battle of Ambon occurred on the island of Ambon in the Dutch East Indies, during World War II. Japan invaded and conquered the island in a few days, facing Dutch, American and Australian forces. The chaotic and sometimes bloody fighting was followed by a series of major Japanese war crimes.

The Japanese occupation of the Andaman Islands occurred in 1942 during World War II. The Andaman and Nicobar Islands, are a group of islands situated in the Bay of Bengal at about 1,250 km (780 mi) from Kolkata, 1,200 km (750 mi) from Chennai and 190 km (120 mi) from Cape Nargis in Burma. Until 1938 the British government used them as a penal colony for Indian and African political prisoners, who were mainly put in the notorious Cellular Jail in Port Blair, the biggest town (port) on the islands. Today they form a Union Territory of India.

The Aso Mining forced labour controversy concerns the use of Allied prisoners of war (POW) and Korean conscripts as labourers for the Aso Mining Company in Japan during World War II. Surviving labourers and other records confirmed that the prisoners and conscripts were forced to work in harsh, brutal conditions for little-to-no pay and that some died, at least in part, because of the ill-treatment at the mine.

The Bangka Island massacre was committed during World War II in the Pacific, on Bangka Island, east of Sumatra in the Indonesian archipelago. On 16 February 1942, Imperial Japanese soldiers machine-gunned 22 Australian Army nurses and 60 Australian and British soldiers and crew members who had survived the sinking of Vyner Brooke by Japanese bombers. South Australian nurse Sister Lt Vivian Bullwinkel and two soldiers were the sole survivors.

The Bataan Death March was the forcible transfer by the Imperial Japanese Army of 60,000–80,000 American and Filipino prisoners of war from Saysain Point, Bagac, Bataan and Mariveles to Camp O'Donnell, Capas, Tarlac, via San Fernando, Pampanga, where the prisoners were loaded onto trains. The transfer began on April 9, 1942, after the three-month Battle of Bataan in the Philippines during World War II. The total distance marched from Mariveles to San Fernando and from the Capas Train Station to Camp O'Donnell is variously reported by differing sources as between 60 and 69.6 miles. Differing sources also report widely differing prisoner of war casualties prior to reaching Camp O'Donnell: from 5,000 to 18,000 Filipino deaths and 500 to 650 American deaths during the march. The march was characterized by severe physical abuse and wanton killings, and was later judged by an Allied military commission to be a Japanese war crime.

Batu Lintang camp at Kuching, Sarawak on the island of Borneo was a Japanese internment camp during the Second World War. It was unusual in that it housed both Allied prisoners of war (POWs) and civilian internees. The camp, which operated from March 1942 until the liberation of the camp in September 1945, was housed in buildings that were originally British Indian Army barracks. The original area was extended by the Japanese, until it covered about 50 acres. The camp population fluctuated, due to movement of prisoners between camps in Borneo, and as a result of the deaths of the prisoners. It had a maximum population of some 3,000 prisoners.

The total death toll of the Nanjing Massacre is a highly contentious subject in Chinese and Japanese historiography. Following the outbreak of the Second Sino-Japanese War, the Japanese Imperial Army marched from Shanghai to the Chinese capital city of Nanking, and though a large number of Chinese POWs and civilians were slaughtered by the Japanese following their entrance into Nanking on December 13, 1937, the precise number remains unknown. Since the late-1960s when the first academic works on the Nanking Massacre were produced, estimating the approximate death toll of the massacre has been a major topic of scholarly debate.

The Faha Massacre Site is located just behind the Pigua cemetery in the village of Merizo on the United States island of Guam. The site is demarcated by four concrete pillars, connected by metal cables, with several crosses placed inside that area. A metal plaque mounted on a concrete block commemorates the thirty native Chamorro men who were slaughtered here on July 16, 1944 by members of the Imperial Japanese Army (IJA) during the Japanese occupation of the island during World War II. The IJA routinely forced Guam's native population to work on its construction projects. The men who were killed here were rounded up for a work crew; why they were killed is unclear, as there were no survivors. The massacre took place one day after the Tinta Massacre, and about one week before the liberation of the island began.

It now generally refers to the ships used by the Imperial Japanese Navy and Imperial Japanese Army to transport Allied prisoners of war (POWs) and romushas out of the Dutch East Indies, the Philippines, Hong Kong and Singapore in World War II. These POWs were taken to Japan, Taiwan, Manchukuo, Korea, the Moluccas, Sumatra, Burma, or Siam to be used as forced labor.

Hellfire Pass is the name of a railway cutting on the former Burma Railway in Thailand which was built with forced labour during the Second World War, in part by Allied prisoners of war. The pass is noted for the harsh conditions and heavy loss of life suffered by its labourers during construction.

Ianjo (慰安所) is a military brothel, established by Japanese during World War II. First ianjo was founded in Shanghai, China. Based on these estimates, most international media sources quote about 200,000 young women were kidnapped by Japanese soldiers to serve in military brothels. The BBC quotes "200,000 to 300,000", and the International Commission of Jurists quotes "estimates of historians of 100,000 to 200,000 women."

In March 1944, a force of three Imperial Japanese Navy (IJN) heavy cruisers raided Allied shipping in the Indian Ocean. The cruisers departed Japanese-held territory on 1 March with the support of other IJN vessels and aircraft. On 9 March, they encountered and sank the British steamer Behar, with the heavy cruiser Tone picking up over 100 survivors. Fearing detection, the Japanese force subsequently returned to the Netherlands East Indies (NEI), arriving on 16 March. Two days later, most of Behar's crew and passengers were murdered on board Tone. Following the war the commander of the raid, Rear Admiral Naomasa Sakonju, was executed for this war crime and Tone's captain Haruo Mayuzumi (ja:黛治夫) was sentenced to seven years imprisonment.

The Jinan incident or 3 May Tragedy began as a 3 May 1928 dispute between Chiang Kai-shek's National Revolutionary Army (NRA) and Japanese soldiers and civilians in Jinan, the capital of Shandong province in China, which then escalated into an armed conflict between the NRA and the Imperial Japanese Army. Japanese soldiers had been deployed to Shandong province to protect Japanese commercial interests in the province, which were threatened by the advance of Chiang's Northern Expedition to reunite China under a Kuomintang government. When the NRA approached Jinan, the Beiyang government-aligned army of Sun Chuanfang withdrew from the area, allowing for the peaceful capture of the city by the NRA. NRA forces initially managed to coexist with Japanese troops stationed around the Japanese consulate and businesses, and Chiang Kai-shek arrived to negotiate their withdrawal on 2 May. This peace was broken the following morning, however, when a dispute between the Chinese and Japanese resulted in the deaths of 13–16 Japanese civilians. The resulting conflict resulted in thousands of casualties on the NRA side, which fled the area to continue northwards toward Beijing, and left the city under Japanese occupation until March 1929.
