A sequel, "Itsuka" (1992), was rewritten and retitled "Emily Kato" (2005). "Obasan" has been named as one of the most important books in Canadian history by the "Literary Review of Canada" and was also listed by "The Toronto Star" in a "Best of Canada" feature. "Obasan" was later adapted into a children's book, "Naomi's Road" (1986), which, in turn, Vancouver Opera adapted into a 45-minute opera that toured elementary schools throughout British Columbia. The opera was also performed before the general public in the greater Vancouver area, Red Deer and Lethbridge, Alberta, Seattle, Washington, and Ottawa, Ontario, at the National War Museum. Revival performances in November 2016 by Toronto's Tapestry Opera won rave reviews, especially in the "Toronto Star", which recognized their setting as one "steeped in significance: St. David's is the home of the last Japanese-Canadian Anglican parish in the city."
