- For the 18th century official, see Mizuno Tadakuni (kanjo bugyo).
He attempted to do away with the kabunakama guilds, in order to combat monopolies, but this and many of his other reforms were resisted so strongly by the merchants of Osaka (and others) that he was forced to abandon his efforts.
Personal and political conflicts with Manabe Akikatsu led to Manabe's resigning as rôjû in 1843. He was later exiled and placed under house arrest in his place of exile; shogun Tokugawa Ieyoshi declared him released from these sentences on 1851/2/15, but Tadakuni died the following day, before word reached him of his release.
