Hideaki Kase

Hideaki Kase (加瀬英明) is a foreign affairs commentator and the director of Alliance for Truth about Comfort Women, a revisionist group. He also leads Society for Dissemination of Historical Fact and is a leader of Japan Conference. Kase was interviewed in a 2007 documentary film about Iris Chang, the author of “The Rape o Nanking,” in which he argued that Nanking massacre did not take place.

Kase is said to be the author of “Minikui Kankoku-jin (Ugly Koreans),” which was published under the name of a fictitious Korean journalist. The book glorified the Japanese colonial rule of Korean peninsula, criticizing Korean people for their faulty remembrance of history. Some of his books are published by the Happy Science.

Japan Education Rebirth Institute

Japan Education Rebirth Institute (Nippon Kyoiku Saisei Kiko, 日本教育再生機構) is a right-wing Japanese group promoting revisionist history and civil textbooks that do not mention the comfort women system and other atrocities committed by the Japanese military while offering narratives glorifying Japanese expansionism. It was founded by Hidetsugu Yagi (八木秀次) after he and others left the Japanese Society for History Textbook Reform due to an internal division. Board members include Shiro Takahashi and others who are affiliated with the powerful Japan Conference. As of 2018, the Institute’s website disappeared, and it is unclear whether the Institute still remains active.

Japanese Society for History Textbook Reform

Japanese Society for History Textbook Reform (新しい歴史教科書をつくる会) is a Japanese nationalist group founded by Nobukatsu Fujioka (藤岡信勝) in 1996, mainly in response to the inclusion of the comfort women history in Japanese history textbooks in the early to mid-1990s.

After a series of in-fighting and schisms among conservative intellectuals throughout 1990s and 2000s, more mainstream conservative leaders (especially those affiliate with Japan Conference) left the organization to form the Society to Improve Textbooks (教科書改善の会), leaving Fujioka and his followers behind. Fujioka’s group continues to publish textbooks, but it has been less successful than the splinter group in getting its textbooks adapted by schools. Both groups’ textbooks are similar in their nationalist (and often revisionist) tendencies, but Fujioka and his group have been more vocal in comfort women denial and criticisms of Abe administration’s handling of the issue.

He is also affiliated with the Japan Family Value Society (FAVS, 家族の絆を守る会), part of Japan Conference’s anti-feminist network.

Hosoya co-authored the booklet “Comfort Women Issue: From Misunderstandings to Solution” with Yumiko Yamamoto of Nadeshiko Action.

The Facts (2007)

“The Facts” is a paid advertisement published in the June 14, 2007 issue of The Washington Post by a group of Japanese conservatives calling themselves the Committee for Historical Facts in an attempt to dissuade the U.S. House of Representatives from adopting H.Res.121, a resolution urging Japan to “formally acknowledge, apologize, and accept historical responsibility in a clear and unequivocal manner for its Imperial Armed Forces’ coercion of young women into sexual slavery.”

Co-signed by dozens of political and public leaders in Japan, the ad is often said to have accelerated the passage of the house resolution by giving credence to the notion that Japan had not fully accepted historical responsibility, rather than preventing it. Nonetheless, the group published a similar ad, Yes, we remember the facts. (2012) five years later.

The ad features five “facts” regarding comfort women, which are the same old denier talking points debunked long ago.

Committee for Historical Facts is made up of:

  • Taro Yayama (屋山太郎), political commentator
  • Yoshiko Sakurai (櫻井よしこ), journalist
  • Nobuaki Hanaoka (花岡信昭), political commentator
  • Koichi Sugiyama (すぎやまこういち), musician

The Facts 2007

Yes, we remember the facts. (2012)

“Yes, we remember the facts.” is a paid advertisement published in the November 6, 2012 edition of The Star-Ledger, a daily newspaper in New Jersey, by a group of Japanese comfort women deniers calling itself the Committee for Historical Facts. It is a revised version of The Facts (2007) ad, published in the June 14, 2007 issue of The Washington Post.

The ad recycles the same old comfort women denier arguments. The publication took place six months after Palisades Park, New Jersey turned down Japanese officials’ offer of one hundred cherry blossom trees in exchange for removing a small plaque memorializing comfort women.
