China's State Archives Administration is releasing the confessions of 45 Japanese World War Two criminals during the War of Japanese Aggression against China between 1937 and 1945, one a day.

"Bayoneting is more effective than shooting." This is what Shigeru Fujita advocated since he joined the war against China in 1938.

And he told his soldiers to try to kill captives on the battlefield to count them as combat statistics.

"I told all officers, 'Killing people is a quick way to get soldiers accustomed to the battlefield, as it can test their courage. For this purpose, it is better to use the captives.'

Shigeru Fujita was born in 1889 in Japan's Hiroshima Prefecture. He went to north China's Shanxi Province in August 1938. His policy was "burn all, kill all and loot all."

Fujita admitted he killed thousand of people in Shan-xi, Henan and Shandong provinces, with cholera, gas shells and gas canisters.

"Under my command, soldiers drove all inhabitants together and bayoneted them to death, they also burned all their houses," he said.

After Japan surrendered in 1945, Fujita ordered his soldiers to destroy all criminal records and evidence of the Japanese aggression. They also buried special bombs used in the war and destroyed gas masks.

Fujita was captured in Hamhung, on the Korean Peninsula in August 1945.

In a military court, victims recalled the brutal killings.

Victim of Japanese aggression Li Putao said, "We were chased to a field near a well. A Japanese chopped off the head of my father-in-law and mother-in-law. My husband screamed and rushed to the edge of the well. Japanese soldiers cut open his belly and threw him aside. And then they grabbed my four-year-old daughter and bayoneted her."

Fujita admitted all his criminal activities, which he said was the nature of Japanese imperialism.

Over 60 years have passed. But for Chinese people, the memories of that period of history will never fade away.
