This paper deals with images of the medieval warrior's residence in Kaoku-zakko and other early modern writings and examines what is common knowledge in the early modern period and what is characteristic of Kaoku-zakko.
In early modern period, it was common knowledge that warrior's residence had changed in Muromachi era. But that change was usually described by the introduction of Shoin and Genkan, and description by the change in style from Shinden-zukuri to Shoin-zukuri as in Kaoku-zakko was comparatively rare. The notion in Kaoku-zakko that warrior's residence in Kamakura era was different from contemporary court-noble's residence was also rare.
