In Japan's case, there were no 'civilians'; the regime had ordered all people to resist invasion, women and children included, and was even providing training, especially in the area they expected landings in. Our troops faced 'civilians' on Saipan.
The Japanese armed forces burgeoned in 1945 under urgent mobilization from about 4.5 million men under arms to over 6 million by August. But in March, Japan mustered a vast additional body of combatants: every single male age 15 to 60 and every single female age 17 to 40. This inducted about a quarter or more of Japan’s total population, about 18 to 20 million people. Japan lacked uniforms or any other visible marker to distinguish this new sea of combatants from the remaining civilian population. Multiple millions of these nearly mobilized former male and female civilians now combatants, would be in the Kyushu invasion area.

Historian Herbert Bix noted the nadir of Japanese savagery towards prisoners. In eight years of war in China from 1937 to 1945, the Japanese killed at least two to three million Chinese soldiers. When Japan was required to hand over the prisoners of war she held after surrender, she presented a total of 56 Chinese. Almost half of Australian battles deaths in the war (8,000 of 17,000) occurred among those captured by Japan. About 35 percent of American prisoners of war held by Japan perished compared to 0.9 percent of Americans captured by Germany.
Allied military planners faced a bitter truth as they planned for a possible invasion of Japan: there were no distinctions between soldiers and civilians.
