In Japan, potential school textbooks must pass a sequence of evaluations before receiving approval to be used in Japanese schools. First, textbook companies submit a draft of their proposed textbooks to the Japanese Ministry of Education. The Textbook Authorization and Research Council (), an official council of the Ministry of Education, composed of university professors, junior high teachers, checks the draft in accordance with the Ministry's educational curriculum guidelines () to ensure that the contents of the proposed textbook is "objective, impartial, and free from errors." The Ministry of Education will give the company that authored the textbook the opportunity to revise the draft when it is found to contain information that is inconsistent with national guidelines. Once the textbook revisions are complete and the textbook has received the approval of the Ministry of Education, Local Boards of Education select books from a list of authorized textbooks for schools under their jurisdiction. The process of textbook authorization is ongoing and conducted every four years, the results of which are presented to the public the following year.
