Abe Tadaaki
Abe Tadaaki (阿部 忠秋; 1602–1671) was a high-ranking government official in early Edo Japan, serving under the third and fourth Tokugawa shoguns, Iemitsu and Ietsuna. He ruled the Oshi Domain in today’s Saitama Prefecture, with an income of 80,000 koku (earlier 50,000).
He became wakadoshiyori (junior councillor) in 1633 and soon after was made rōjū (Elder Councillor). When Iemitsu died in 1651 and his son Ietsuna, just ten years old, took the throne, many of Iemitsu’s close advisers performed junshi (suicide to follow their lord in death). Abe did not participate and remained to help run the government.
Abe is remembered for his integrity, good morals, and practical approach to governance. He tried to help samurai who became rōnin after the Keian Uprising find legitimate work, rather than expelling all rōnin from Edo. This helped reduce potential threats to the shogunate.
Before his death, Sakai Tadakiyo became head of the rōjū, and Abe openly rebuked him for bribery and for making policy in a piecemeal way instead of pursuing a clear plan.
Abe Tadaaki died in 1671 at age 69. His long service occurred before the Genroku era, a time noted for corruption and excess.
