IN WWII, how exactly did the Japanese mistreat prisoners of war. I know how the Japanese were mistreated, but i never really understood what the...

The Japanese treated the prisoners-of-war that came into their
hand harshly. They were viewed as valueless and as useful only for manual labour. As the war in
the Pacific turned against Japan, their sense of desperation only further aggravated such extreme
behaviour - contempt eased the policy of brutality and more atrocities were carried out against
the POWs, who were regarded as merely human charter.

For example, in
Singapore, about 100,000 Allied POWs were forced to live in cramped living conditions and
numerous of them were sent to carry out works, such as cleaning and doing repairs. The usual food
given to these prisoners was thin rice porridge, which resulted in cases of malnutrition and
starvation. Changi Prison, which was designed to hold a maximum of 600 prisoners, was packed in
with over 3000 POWs. Many POWs were also sent under the Japanese regime to constuct a 420
kilometre long railway through the mountainous terrain of Thailand and Burma. Around 60,000
British, Australian, Dutch and American POWs were used as forced labour, which eventually led to
the deaths of around 13,000 of them.
