The Truth about Nanjing

 is a 2007 film by Japanese nationalist filmmaker Satoru Mizushima about the 1937 Nanking Massacre.
Background and funding.
Mizushima said he received more than 200 million yen (US$1.8 million) in donations from 5,000 of his supporters in order to fund the film. The film was backed by nationalistic figures including Tokyo governor Shintaro Ishihara and was intended to expose what the filmmakers saw as propaganda aspects of the Nanking Massacre. Less than a month before the 70th anniversary of the Nanjing massacre, the director said in an interview that Japanese war criminals were martyrs who were made into scapegoats for war crimes as Jesus Christ was nailed to the cross in order to bear the sins of the world, and they died bearing all of old Japan's good and bad parts. Contrary to the scholarly consensus, he also claimed that the Nanjing Massacre was a politically motivated frame-up by China and the numerous Western eyewitnesses whose accounts form the basis of the historical understanding of the Nanjing Massacre. These accounts were, according to the filmmakers, espionage activities.
The film was based on the work of Asia University professor Shūdō Higashinakano who has claimed the massacre was a hoax. Hagasinakano was ordered by a Japanese court to pay compensation to a Chinese woman after he accused her of lying about being a victim of violence by the Japanese in Nanjing.
Mizushima said that the project was meant to counter the film "Nanking", a 2007 American documentary, which he believed was "based on fabrications and gives a false impression" and which he perceives to be a "setup by China to control intelligence". 
Plot.
"The Truth about Nanjing" is a three-part film.
This part shows the last day of the seven people who were condemned to death in 1948 by the International Military Tribunal for the Far East and executed on 23 December 1948 at Sugamo Prison, Tokyo. The film focuses on Iwane Matsui's campaign in Nanking through flashbacks. Focus is put on each of the seven men. 
Reactions.
Tokushi Kasahara, professor at Tsuru University, said other countries were making faithful documentaries and "it is shameful that Japan can only make this kind of film."
Support in Japan.
Journalist Yoshiko Sakurai and a number of serving national-level Japanese politicians came out in support of the film.
