Question:  Seiichi Morimura revealed the atrocities committed by a unit based in which district ?
Context: The İzmit massacres refer to atrocities committed in the region of İzmit, Turkey, during the Greco-Turkish War (1919-1922).  An Allied commission that investigated the incidents, submitted a report, on June 1, 1921, about the events.  In general it accepted the Greek claims that Turkish troops massacred more than 12,000 local civilians, while 2,500 were missing and stated that the atrocities committed by the Turks in the Izmit peninsula ""have been more considerable and ferocious than those on the part of the Greeks"". The Rape of Nanking: The Forgotten Holocaust of World War II is a bestselling 1997 non-fiction book written by Iris Chang about the 1937–1938 Nanking Massacre, the massacre and atrocities committed by the Imperial Japanese Army after it captured Nanjing, then capital of China, during the Second Sino-Japanese War.  It describes the events leading up to the Nanking Massacre and the atrocities that were committed.  The book presents the view that the Japanese government has not done enough to redress the atrocities.  It is one of the first major English-language books to introduce the Nanking Massacre to Western and Eastern readers alike, and has been translated into several languages. James Hawkins, from Maysville, Kentucky, was a Battlefield commissioned Second lieutenant and field operations leader of the United States Army Tiger Force commando unit, 1st Battalion (Airborne), 327th Infantry Regiment, 1st Brigade (Separate), 101st Airborne Division, during the Vietnam War.  The unit was featured in the Pulitzer Prize winning book "," written by "Toledo Blade" reporters Michael D. Sallah and Mitch Weiss (the Pulitzer Prize included a third "Blade" reporter Joe Mahr).  The U.S. Army Criminal Investigation Command investigated the Tiger Force for "atrocities," including torture, maiming, rape, and murder of unarmed villagers, including babies, children, and the elderly, during operations in the Song Ve Valley.  The Army did not file charges against Tiger Force soldiers, including their acting platoon leader, Hawkins.  The investigations into the atrocities committed by Tiger Force occurred after reports and investigations into atrocities by United States Army soldiers in the My Lai Massacre.  Hawkins attributes the lack of charges to the timing of the investigation after My Lai and the potential for additional bad "publicity." Unit 731 (Japanese: 731部隊 , Hepburn: Nana-san-ichi Butai ) was a covert biological and chemical warfare research and development unit of the Imperial Japanese Army that undertook lethal human experimentation during the Second Sino-Japanese War (1937–1945) of World War II.  It was responsible for some of the most notorious war crimes carried out by Japan.  Unit 731 was based at the Pingfang district of Harbin, the largest city in the Japanese puppet state of Manchukuo (now Northeast China). The Manila massacre involved atrocities committed against Filipino civilians in the City of Manila, the capital of the Philippines by Japanese troops during World War II at the Battle of Manila in 1945.  The Manila massacre was one of several major war crimes committed by the Imperial Japanese Army, as judged by the postwar military tribunal.  The Japanese commanding general, Tomoyuki Yamashita, and his chief of staff Akira Mutō, were held responsible for the massacre and other war crimes in a trial in late 1945 in Manila.  Yamashita was executed on 23 February 1946 and Mutō on 23 December 1948. Massacres of Karadak (1941-1945) were part of a series of atrocities and massacres committed against Albanians of Karadak, Presevo, by Serbian, Macedonian and Bulgarian Chetnik and Partisan forces between the years of 1941-1945.  There were atrocities committed in the villages of Bugarinë, Muhaxhieret Ranatoc, Shushaja e Poshtme, Bilinicë, Lagja Kukaj, Pecenë, Gruhali, Norce, Linicë, Kokaj and Sllubicë.  The total amount of Albanians killed in the region of Karadak during the time is still unknown.  In the village of Isëukaj, 98 Albanians were murdered.  In 2016, TV news agency RTV Preseva published an article about the memorial which stands today in Presevo. Nobukatsu Fujioka (藤岡 信勝 , Fujioka Nobukatsu ) (born October 21, 1943, Shibecha, Hokkaido) is a professor of education at Tokyo University noted for his efforts at removing from Japanese textbooks accounts of wartime atrocities committed by Japan during the Second World War.  He is considered to be a conservative and a nationalist, and has been quoted as saying that he "stand(s) for a viewpoint of history with an emphasis on national interest," and that the study of Japanese history is "subject to the ultimate moral imperative of whether or not it serves to inculcate a sense of pride in being Japanese."  He has also said that to "write [a history] based only on verified historical truths makes...[it] insipid and dry.  I had no choice but to write from my own imagination to a great extent." Seiichi Morimura (森村 誠一 , Morimura Seiichi , born January 2, 1933 in Kumagaya) is a Japanese novelist and author.  He is best known for the controversial "The Devil's Gluttony" (悪魔の飽食) (1981), which revealed the atrocities committed by Unit 731 of the Imperial Japanese Army during the Sino-Japanese War (1937-1945). In mid-August 1943 a Polish unit of the Uderzeniowe Bataliony Kadrowe (English: "Striking Cadre Battalions", "UBK"), which was controlled by the right-wing organization Konfederacja Narodu, organized armed attack on East Prussian villages in the area of Johannisburg (now: Pisz).  The attack was made as revenge for German genocide and atrocities committed against Polish population.  The targets of the attack included devoted Nazis, members of NSDAP and inhabitants engaging in brutality against Polish population.  According to Polish sources, some 70 Germans were killed and 40 German farms were razed to the ground, while an eyewitness reports 13 killed people, including a woman and two children, and two people wounded.  The attack, commanded by Colonel Stanislaw Karolkiewicz, was a revenge for German atrocities, committed in Bezirk Bialystok.  The revenge attack caused shock among Prussian Germans and caused them to rethink their genocidal tactics against Polish population Nicholas Dausi is a Malawian politician.  He served the Hastings Banda government in "several capacities" as a collaborator of Banda.  Dausi was "accused of withholding information on atrocities committed during the dictatorship", after he himself publicly stated that he had evidence which could help in successfully convicting those who were accused of committing various atrocities during Dr. Banda's rule; but was freed on bail.  He has also served as publicist and Vice President of the Malawi Congress Party (MCP).  He was Deputy Minister for Presidential Affairs in 2010.
