Aftermath

The Japanese occupation of Singapore started after the British surrender. Japanese newspapers triumphantly declared the victory as deciding the general situation of the war. The city was renamed Syonan-to (Japanese: 昭南島 Shōnan-tō; literally: Southern Island gained in the age of Shōwa). The Japanese sought vengeance against the Chinese and to eliminate anyone who held anti-Japanese sentiment. The Japanese authorities were suspicious of the Chinese because of the Second Sino-Japanese War, and killed many in theSook Ching massacre. The other ethnic groups of Singapore—such as the Malays and Indians—were not spared. The residents would suffer great hardships under Japanese rule over the following three and a half years.

Many of the British and Australian soldiers taken prisoner remained in Singapore's Changi Prison. Many would never return home. Thousands of others were shipped on prisoner transports known as "hell ships" to other parts of Asia, including Japan, to be used as forced labour on projects such as the Siam–Burma Death Railway and Sandakan airfield in North Borneo. Many of those aboard the ships perished.

An Indian revolutionary Rash Behari Bose formed the Indian National Army with the help of the Japanese, who were highly successful in recruiting Indian soldiers taken prisoners. From a total of about 40,000 Indian personnel in Singapore in February 1942, about 30,000 joined the pro-Indian Independence Indian National Army, which fought Allied forces in the Burma Campaign as well as in North-east Indian regions of Kohima and Imphal. Others became POW camp guards at Changi. An unknown number were taken to Japanese-occupied areas in the South Pacific as forced labour. Many of them suffered severe hardships and brutality similar to that experienced by other prisoners of Japan during the war. About 6,000 of them survived until they were liberated by Australian and US forces in 1943–45.

After the Japanese surrender in 1945, Yamashita was tried by a US military commission for war crimes committed by Japanese personnel in the Philippines earlier that year, but not for crimes committed by his troops in Malaya or Singapore. He was convicted and hanged in the Philippines on 23 February 1946.
