Collector has 'proof' of atrocities

A simple room in an apartment in Jiamusi, Heilongjiang province, serves as a powerful testimony to one man's determination - often against great odds - to set the record straight about the brutal reality of Japan's wartime aggression in the 1930s and 1940s.

Song Jinhe, 67, a retired cadre, began to collect documents and photographs in the 1960s.

The graphic and chilling details of the nearly 10,000 items on display provide a powerful rebuttal to the Japanese political right wing's denials that the Japanese imperial army committed widespread atrocities.
