 As a result of junshi being practiced so widely, it was outlawed by a number of daimyō.It was outlawed by the Saga clan in 1661, and then entirely in the version of the "Buke Sho-Hatto" (The Law for Military Houses) by the fourth Tokugawa Shōgun Ietsuna (1651-1680) in 1663; "Junshi" was seen by the "bakufu" to contain certain elements of sedition.The enforcement of this law was strict, and worked in the customary Japanese way by laying the blame for an instance of "junshi" on the son or successor of the deceased lord whose death had occasioned it.
