Tenno Kammu was born in 737. He was the son of Emperor Konin.
Tenno Kammu reigned from 781 to 806. He had a strong leadership and attempted to reform the Japanese political institution to rid the malady of the Buddihism politics. He has moved the capital of Japan twice. First, he moved it from Nara (Heijo-kyo) which many big temples were in to Nagaoka ( Nagaoka-kyo ) in 784. Nagaoka was in the present Kyoto prefecture. Ten years later (794), He moved it from Nagaoka to Heian-kyo which were in the northeast of Nagaoka. He prohibited big temples from moving to Heian-kyo.
In addition to reforming the political institution, Emperor Kammu attempted to put the Ezo (the present Tohoku district ) under control. He has put down the rebellion many times. But he couldn't accomplish his mission easily. Finally, Sakanoue no Tamuramaro who was appointed shogun by Emperor Kammu suppressed almost the rebellion "Emishi", built the castle "Izawajo". Conquering the "Emoshi" was taken over by his sons, Emperor Heizei, Emperor Saga, and Emperor Junna.
