Emperor Toba (鳥羽天皇, Toba-tennō, February 24, 1103 – July 20, 1156) was the 74th emperor of Japan. Toba's reign spanned the years from 1107 through 1123. He became Emperor when he was 5 years old. He abdicated the throne when he was 20 years old. At this time the Emperors of Japan only filled a background role in politics. The elaborate court system of Insei was coming to an end as Japan had already turned to feudalism and Militarism.
