Survivors of the Bombing of Chongqing during World War II on Wednesday sued the Japanese government over its wartime antihuman bombings in Chongqing, the then Chinese capital, demanding an apology from the government and compensation.

The accusers, Su Yuankui from Chongqing, Luo Shuqin from Zigong in Sichuan Province and Xu Yong, a history professor at Peking University, testified at Tokyo District Court.

The lawsuit is the 26th court session related to the case since 2006.

Su, 80, said in court that two of his relatives were killed during bombings in August 1940 and June 1941 and all of his property was destroyed in the bombardments, while Luo said her mother lost her right foot during the bombings. 

"We came here to state and sue over the Japanese government's brutal bombings in Chongqing during World War II and demand the Japanese court makes a just judgment,"Su said before the court session.

"We are here not to recall hatred, but to call for remembering history. We will fight for this goal for the rest of our lives."

The accusers, representing a civil litigation group against the Japanese government over the Chongqing bombings, urged the Japanese government to apologize and demanded 10 million yen ($97,900) for each survivor in the group.

The civil group, formed in April 2004, has formally sued the Japanese government over the catastrophe since March 2006. A total of 188 survivors and relatives of victims from Chongqing and nearby cities have been involved in the lawsuit as plaintiffs.

Xu, during the session, showed several historic documents from the Chinese and Japanese sides which proved that the Japanese military plotted bombing raids against Zigong and carried out seven raids, resulting in significant loss of life and property.

From February 1938 to August 1943, Japan conducted bombing raids over Chongqing and its adjacent areas, dropping over 11,500 devices, mainly incendiary bombs.

Residential areas, business areas, schools and hospitals were the main targets of the attacks in which tens of thousands of civilians were killed.
