Tanuma Okitsugu

Who was Tanuma Okitsugu?

Tanuma Okitsugu was a rōjū of the Tokugawa shogunate who introduced monetary reform. He was also a daimyo, and ruled the Sagara han. He used the title Tonomo-no-kami.

His regime is often identified with rampant corruption and huge inflation of currency. In Tenmei 4, Okitsugu's son, the wakadoshiyori Tanuma Okitomo, was assassinated inside Edo Castle. Okitomo was killed in front of his father as both were returning to their norimono after a meeting of the Counselors of State had broken up. Okitomo was killed by Sano Masakoto, a hatamoto. The involvement of senior figures in the bakufu was suspected, but only the assassin himself was punished. The result was that the Tanuma-initiated, liberalizing reforms within the bakufu and the relaxation of the strictures of sakoku were blocked.
