Morinari-shinnō became
Crown Prince in 1200. He was elevated to the throne after
Emperor Go-Toba pressured
Emperor Tsuchimikado into abdicating. •
12 December 1210 (
Jōgen 1, 25th day of the 11th month): In the 12th year of Tsuchimikado
-tennōs reign (土御門天皇十二年), the emperor abdicated; and the succession (
senso) was received by his younger brother, the second son of the former-Emperor Go-Toba. Shortly thereafter, Emperor Juntoku is said to have acceded to the throne (
sokui). In actuality, Emperor Go-Toba wielded effective power as a
cloistered emperor during the years of Juntoku's reign. In 1221, he was forced to abdicate because of his participation in Go-Toba's unsuccessful attempt to displace the
Kamakura bakufu with re-asserted Imperial power. This political and military struggle was called the
Jōkyū War or the Jōkyū Incident (
Jōkyū-no ran). After the
Jōkyū-no ran, Juntoku was sent into exile on
Sado Island (佐渡島 or 佐渡ヶ島, both
Sadogashima), where he remained until his death in 1242. This emperor is known posthumously as Sado-no In (佐渡院) because his last years were spent at Sado. He was buried in a mausoleum, the
Mano Goryo, on Sado's west coast.

Daijō-kan included: •
Kampaku,
