A group of mainland scholars will visit Japan to take part in activities commemorating Saturday's 60th anniversary of the Nanjing Massacre.
Professor Zhang Kaiyuan, of Wuhan Huazhong Normal University, will lead a delegation to attend a seminar in Tokyo.
Professor Gao Xinzhu, of Nanjing University, will join Zhu Chengshan, curator of the Nanjing Massacre Memorial Hall, for a similar conference in Osaka.
Professors Zhang and Gao are authorities on research into the massacre.
Professor Zhang said he would deliver a speech at the Tokyo seminar and talk about his research into wartime records compiled by American historian Miner Searle Bates, which claimed that at least 300,000 Chinese were killed by Japanese troops during the 1937 massacre.
Professor Zhang said he had found abundant records kept by the historian in the Deity Library at Yale University documenting the atrocities.
With the recently discovered diary of German businessman John Rabe, there was now solid evidence Japanese soldiers had slaughtered hundreds of thousands of Chinese citizens in the six-week rampage, he said.
