- Historical Notes
Kazusada Sumiyama’s son, Yoichi Sumiyama Sugiyama, was one of 24 Japanese nationals killed on 9/11. After a 2004 memorial for 9/11 victims, Sumiyama bought an English-language copy of the The 9/11 Commission Report. In 2008, he read a Japanese translation and realized that it omitted chapters describing the terrorists’ motives. Determined to make the record complete, Sumiyama began translating the full report, an effort that took a decade.
Sumiyama was methodical in his work, translating about three pages a day with this annotated copy of the 9/11 Commission Report and a photo of his son Yoichi nearby. His Japanese-language version was published in 2021 for the 20th anniversary of the attacks, supported by a crowdfunding campaign that raised approximately $45,000. He hoped that his expanded translation would help make clear the costs of terrorism and encourage people to embrace peace and freedom. This was, he said, “the earnest wish of a father who lost his beloved son amid the great flow of history.”
