The Association of Nonpartisan Diet Members Considering the Issue of History Textbooks is a group presided over by Diet member Shoichi Nakagawa. At the end of the ordinary Diet session, the group examined and discussed officially approved high school textbooks.
Many of these textbooks remain full of self-torturing historical perceptions. They emphasize particularly dark aspects of Japan’s past and omit historical achievements Japan should be pride of. A high school student who reads those textbooks and is asked about their impression would probably answer, “Japan is a terrible country and Japanese are the worst people.”
For example, a section on the Nanjing Massacre states, “The Chinese side declared that more than 300,000 people were massacred by the Japanese military.”
[Omission] We Diet members must protest against teaching high school students figures that are obviously wrong!
[Omission] Several textbooks also mentioned the incorrect Japanese term “comfort women.”
[Omission] Diet members are furious. It is unacceptable to write such falsehoods in textbooks. One textbook said, “A visit to Yasukuni Shrine by the sitting prime minister and provisions of the Law Regarding the National Flag and National Anthem can be understood as manifestations of reactionary nationalism.” [Omission] Diet members are angry and believe a textbook that criticizes the current prime minister’s actions and a law passed with the approval of most Diet members is the problem.
[Omission] Due to the influence of a certain organization of school teachers that dominates the adoption of textbooks, it is reported that the more the content of a history textbook is self-torturing and left-leaning, the better it sells. Because textbook companies’ top priority is selling books, they have given important posts to authors who write text based on self-torturing perceptions of history.
Can Japan simply accept this? The nation’s education system has drifted away from nurturing feelings of love for our nation among students. Given this, the Ministry of Education, Culture, Sports, Science and Technology should at least make greater efforts to ensure textbook content is correct.
