The education ministry plans to revise guidelines for textbooks for elementary, junior high and high schools, and introduce requirements reflecting the government's position on "historical facts," officials said.

The revision is in line with calls by the ruling Liberal Democratic Party, led by Prime Minister Shinzo Abe, to instill a sense of national pride in students and correct what some LDP members call a "self-condemning" view of historical events, including the Nanjing Massacre and wartime sex slaves.

The Ministry of Education, Culture, Sports, Science and Technology also wants the textbooks to include more material that would encourage children to be more patriotic and respectful of traditional culture, the officials said Wednesday.
