The record

The Nationalist government under Chiang Kai-shek and the Communist forces both fought Japan. Their own war paused and then resumed after Japan's defeat.

Deaths are estimates, not a census. Chinese military and civilian losses are commonly put in the tens of millions, and the range is disputed. Japanese losses in China are not the same figure as Japan's losses in the whole of the Second World War. This page does not print a single total as if it were settled.

The killing in particular cities and units is not narrated here. A later pass can add a sourced account of a named massacre on its own page, marked graphic, rather than fold it into a paragraph with no source line.
