Moving to the shōgun-"shugo" relationship, in the 1380s the "kanrei" council system was strengthened by Yoshimitsu when he persuaded the western and central "shugo" lords to take up residence in Kyoto. He even went to visit Ouchi Yoshihiro in 1389, and persuaded him to live in Kyoto during one of his so-called pilgrimage circuits. These circuits were used to display his power through the provinces in which he traveled. This compulsory residential policy that Yoshimitsu instituted was the main coercive policy that aided the "kanrei" council system, and enabled the shōgun to tighten his grip around the "shugo" lords. Permission to leave the capital city was rarely granted to the "shugo" lord: it was only granted after discussion in the Senior Vassal Council. Even when permission was granted in the case of provincial rebellion or Southern Court guerilla activity, suitable hostages were left behind in Kyoto. If the "shugo" lord left without permission, it was seen as tantamount to treason.
