Like her character in "The Bracelet," Yoshiko Uchida was taken to an internment camp during World War II. On the day Pearl Harbor was bombed, her family was split apart—her father was taken away and interned. Yoshiko, her mother, and her brother were taken to a camp in Topaz, Utah, where they waited out the war. There she witnessed her grandfather’s death; a guard who saw him looking for arrowheads assumed he was trying to escape and shot him. Uchida recounts her internment experience in Journey to Topaz (1971).
Uchida wrote many books for young people, among them The Dancing Kettle and Other Japanese Folk Tales (1949) and The Invisible Thread: A Memoir (1991).
