Emperor Hirohito reigned for more than sixty years, yet we know little about him or the part he really played in the turbulent history of Showa Japan.Stephen Large draws on a wide range of Japanese and Western sources in his study of Emperor Hirohito's political role in Showa Japan (1926-89). This analysis focuses on key events in his career such as the extent to which he bore responsibility for Japanese aggression in the Pacific in 1941, and explains why Hirohito remains such a contested symbol in Japanese post war politics.
