The Tokyo metropolitan board of education adopted on Thursday a disputed civics textbook which was authored by rightist nationalists to be used in a metropolitan government-run high school in Tokyo.
Five of the six-member board voted in favor of the book for use at Hakuo High School's junior high division. The other member was absent from the session, Kyodo News said.
The civics textbook, to be used from next April, has been criticized for whitewashing Japan's past and discussing positively the Self-Defense Forces' international activities.
The textbook is compiled mainly by members of a group of nationalistic academics called the Japanese Society for History Textbook Reform and is published by Fusosha Publishing Inc.
Four six-year middle schools, run by the Tokyo metropolitan government, have used Fusosha's controversial history textbook since last April. The history textbook has been widely criticized for distorting the history of Japan's aggression war against its Asian neighbors and glorifying Japanese aggressors' atrocities on Asian people.
