Explanation:

During the A.D. 800s, the emperor’s power abated. After a time of powerful emperors, several weak emperors occurred to the throne. Many of these emperors were still only children, and court administrators known as regents had to administer for them. A regent is a personality who rules for an emperor who is too childlike or too sick to rule. When the emperors grew up, however, the regents declined to give up their power.  

Most regents came from a group called the Fujiwara. Under the Fujiwara, Japan’s emperors were acknowledged, but they no extended had real power. Rather of the ruling, these emperors spent time studying Buddhism or writing poetry in their palace at Heian.
