[Sponsored by the Nagasaki Peace Museum last July 9, the top Japanese researcher on Japan's wartime biological weapons (BW) program, Tsuneishi Keiichi, gave a public lecture in Nagasaki together with the director of China's Unit 731 War Crimes Museum in Harbin. Tsuneishi's talk, entitled “The Image and Reality of Unit 731,” explained the declassified American intelligence records he discovered in 2005, revealing that U.S. Occupation authorities not only granted immunity from prosecution to Japanese scientists in exchange for their unrivaled BW data, but also made direct cash payments to obtain their experimental results.
