 The Hōjō family crest in the city is therefore still ubiquitous.From the middle of the thirteenth century, the fact that the vassals (the "gokenin") were allowed to become "de facto" owners of the land they administered, coupled to the custom that all "gokenin" children could inherit, led to the parcelization of the land and to a consequent weakening of the shogunate.This, and not lack of legitimacy, was the primary cause of the Hōjō's fall.
