The surviving flying personnel returned to Mito, Japan, by transport plane in December 1944. At Mito the unit re-equipped with the III Ko before moving to Saigon, Indo-China in February 1945. In April part of the unit moved to Formosa and was assigned to special attack duties as the Makoto (誠 - honesty or sincerity) 204 Sentai to participate in the Okinawa campaign and in July 1945 the main force of the unit joined it there.
