Japan war atrocities 'lies and fabrication'

Seventy years after the end of World War Two, revisionism in Japan is growing stronger and becoming more mainstream.

Some are denying that Japan committed war atrocities, including forcing women in China, South Korea and South East Asia to be comfort women, or sex slaves for Japanese soldiers.

One of these revisionists is Toshio Tamogami, the former chief of Japan's air forces.
