Emperor Kammu - Traditional Narrative

Traditional Narrative

Kammu's personal name (imina) was Yamabe (山部?). He was the eldest son of Prince Shirakabe (later known as Emperor Kōnin), and was born prior to Shirakabe's ascension to the throne. According to the Shoku Nihongi (続日本紀?), Yamabe's mother, Yamato no Niigasa (later called Takano no Niigasa), was a 10th generation descendant of Muryeong of Baekje.

After his father became emperor, Kammu's half-brother, Prince Osabe was appointed to the rank of crown prince. His mother was Princess Inoe, a daughter of Emperor Shōmu; but instead of Osabe, it was Kammu who was later named to succeed their father. After Inoe and Prince Osabe were confined and then died in 775, Osabe's sister – Kammu's half-sister Princess Sakahito – became Kammu's wife. Later, when he ascended to the throne in 781, Kammu appointed his young brother, Prince Sawara, whose mother was Takano no Niigasa, as crown prince. Hikami no Kawatsugu, a son of Emperor Temmu's grandson Prince Shioyaki and Shōmu's daughter Fuwa, attempted to carry out a coup d'état in 782, but it failed and Kawatsugu and his mother were sent into exile. In 785 Sawara was expelled and died in exile.

Kammu had 16 empresses and consorts, and 32 imperial sons and daughters. Among them, three sons would eventually ascend to the imperial throne: Emperor Heizei, Emperor Saga and Emperor Junna. Some of his descendants (known as the Kammu Taira or Kammu Heishi) took the Taira hereditary clan title, and in later generations became prominent warriors. Examples include Taira no Masakado, Taira no Kiyomori, and (with a further surname expansion) the Hōjō clan. The waka poet Ariwara no Narihira was one of his grandsons.

Kammu is traditionally venerated at his tomb; the Imperial Household Agency designates Kashiwabara no Misasagi (柏原陵?, Kashiwabara Imperial Mausoleum), in Fushimi-ku, Kyoto, as the location of Kammu's mausoleum.
