 of 1637. Though the suppression of this rebellion quelled all serious threats to Tokugawa rule, it was nonetheless an unsure era. Ietsuna was a frail child, and this carried over into his adult years. Nothing else is known of his youth.

Shogunal Regency (1651-1663)

Tokugawa Iemitsu died in early 1651, at the age of forty seven. After his death, the Tokugawa dynasty was at major risk. Ietsuna, the heir, was only ten years old. Nonetheless, despite his age, Minamoto no Ietsuna became shogun in Kei'an 4 (1651). Until he came of age, five regents were to rule in his place; but Shogun Ietsuna nevertheless assumed a role as formal head of the bakufu bureaucracy.

In this period, regents exercised power in the shogun's name. These were Sakai Tadakatsu

 or the "Tosa Conspiracy". Chuya was brutally executed along with his family and Shosetsu's family. Shosetsu choose to commit seppuku rather than being captured.

In 1652, about 800 ronin led a small disturbance on Sado Island, and this was also brutally suppressed. But for the most part, the remainder of Ietsuna's rule was not disturbed anymore by the ronin as the government became more civilian oriented.

In Meireki 3 (1657), on the 18th-19th day of the 1st month, when Shogun Ietsuna was almost 20 years old, a great fire erupted in Edo and burned the city to the ground. It took two years to rebuild the city and bakufu officials supervised the rebuilding of the city. In 1659, Shogun Ietsuna presided over the opening ceremonies.

Bakufu Power Struggle (1663-1671)

In 1663, the regency for Shogun Ietsuna ended, but the regents still held power for him, the first time that the power behind the bakufu was not a former shogun. Ietsuna's chief advisors were now Hoshina Masayuki, Ietsuna's uncle (whom he had deep regard for) Itakura Shigenori

. By 1671, however, many of the former regents were either dead or retired, and Ietsuna began to rule in his own right.

Shogun Ietsuna (1671-1680)

Following the succession dispute of the Date, very few disturbances occurred for the remainder of Ietsuna's reign, except some defiant daimyo.

In 1679, Shogun Ietsuna fell ill. His succession began to be discussed, in which Sakai Tadakiyo

 took an active role. He suggested that a son of Emperor Go-Sai become the next shogun, following the precedent of the later Kamakura shoguns, who in reality were members of the blood royal. Tadakiyo probably saw himself as becoming powerful like the Hōjō regents, and thus many members of the Tokugawa blood preferred the son of Shogun Iemitsu and Shogun Ietsuna's younger brother, Tokugawa Tsunayoshi

, to become shogun.
  • June 4, 1680 (Enpō 8, 8th day of the 5th month): Shogun Ietsuna dies; and he is succeeded as shogun by Tsunayoshi.


Tadakiyo retired, embarrassed, and shortly after, Tokugawa Ietsuna died in 1680. His posthumous name was Genyūin. He was succeeded by his younger brother, Tsunayoshi.

Though Ietsuna proved to be an able leader, affairs were largely controlled by the regents his father had appointed, even after Ietsuna was declared old enough to rule in his own right.
