After his release, Higashide elected to stay in the U.S. and eventually became a citizen. For years, he was a leader in the effort to obtain redress from the American government for the violation of the human rights of the Peruvian Japanese internees. In 1981 he testified before the Commission on Wartime Relocation and Internment of Civilians.

Higashide's moving memoir was translated from Japanese into English and Spanish through the efforts of his eight children, and was first published in 1993. This second edition includes a new Foreword by C. Harvey Gardiner, professor emeritus of history at Southern Illinois University and author of Pawns in a Triangle of Hate: The Peruvian Japanese and the United States; a new Epilogue by Julie Small, cochair of Campaign for Justice-Redress Now for Japanese Latin Americans; and a new Preface by Elsa H. Kudo, eldest daughter of Seiichi Higashide.
