First, I want to say that I absolutely believe that this book should still be included in school curriculum. The only thing 'new' about it is that pages and passages were added. Nothing was taken out and the translation was not changed. Reports that the book is so different that it's nothing like the original are false. Reports that the story is different are false.

“You want to know about my motivation, don't you? Well. It is the kind of sentiments anyone would have when he actually sees refugees face to face, begging with tears in their eyes. He just cannot help but sympathize with them. Among the refugees were the elderly and women. They were so desperate that they went so far as to kiss my shoes, Yes, I actually witnessed such scenes with my own eyes. Also, I felt at that time, that the Japanese government did not have any uniform opinion in Tokyo. Some Japanese military leaders were just scared because of the pressure from the Nazis; while other officials in the Home Ministry were simply ambivalent.
The Nazis used the phrase Lebensunwertes Leben (life unworthy of life) in reference to the disabled and mentally ill.[92] On 14 July 1933, the Law for the Prevention of Hereditarily Diseased Offspring (Gesetz zur Verhütung erbkranken Nachwuchses), the Sterilization Law, was passed, allowing for compulsory sterilization.[93][94] The New York Times reported on 21 December that year: "400,000 Germans to be sterilized".[95] There were 84,525 applications from doctors in the first year. The courts reached a decision in 64,499 of those cases; 56,244 were in favor of sterilization.[96] Estimates for the number of involuntary sterilizations during the whole of the Third Reich range from 300,000 to 400,000.[97]
Josef Mengele (/ˈmɛŋɡələ/; German: [ˈmɛŋələ]; 16 March 1911 – 7 February 1979) was a German Schutzstaffel (SS) officer and physician in Auschwitz concentration camp during World War II. He performed deadly human experiments on prisoners and was a member of the team of doctors who selected victims to be killed in the gas chambers. Arrivals that were judged able to work were admitted into the camp, while those deemed unsuitable for labor were sent to the gas chambers to be killed. With Red Army troops sweeping through Poland, Mengele was transferred 280 kilometers (170 mi) from Auschwitz to the Gross-Rosen concentration camp on 17 January 1945, just ten days before the arrival of the Soviet forces at Auschwitz. After the war, he fled to South America where he evaded capture for the rest of his life.
