In 1988 Karl published a Japanese version of his diary documenting the experience leading up to & during incarceration at Manzanar; then the following year in 1989 he published it's sequel (also in Japanese), this "MIS Soldier's Diary" which documents his subsequent US Army service as a Japanese linguist in the China-Burma theater. This English translation has been prepared from the original Japanese "Amerika Ichi Jouhou Heishi no Nikki" (アメリカ一情報兵士の日記) with the permission of Karl's three granddaughters, intended as an English-language sequel to his previously translated Manzanar Concentration Camp Diary.
