Born as the fifth son of the businessman Fukasawa Toshishige ( 深 沢 利 重 ), he passed the exam for a state license as a teacher in self-study. Morimoto was a lecturer at Tōkyō rika daigaku , professor at Hiroshima University and Gunma University . In 1927 he married Morimoto Harue ( 森 本 治 枝 ) and took her family name. His second eldest son Morimoto Masaki was a mathematician and astronomer (born May 14, 1932, † November 16, 2010).
