Tadakuni's major reforms were, for example, control of people's consumption through tightening public morals and implementing a sumptuary decree strictly, issuance of "Hitogaeshi-rei" (the decree to force peasants dwelling in urban areas to return to their hometowns), an order on "kabu nakama" to disband itself, and issuance of "Kien-rei."
主な改革としては、綱紀粛正・倹約令徹底による消費の抑制、人返し令による都市住民の農村への帰還、株仲間の解散令、棄捐令などである。
