To reveal the social character of a medieval Japanese city, here, I introduce two reconstructions of Sadaie Fujiwara residence and its environs based on Sadaie's Diary, "Meigetsu-ki". One is 4 site plan indicating lands purchased by Sadaie. The other shows the plan and location of Sadaie Residence and outlines of its surrounding buildings. In accordance with there reconstructions, the social image of this community would be suggested. Amongst feudal lords, landowners and house possessors, there were many artisans and merchants lodged at row-houses without legal superficies. After the Kamakura Era, they obtained leasehold rights and the row-houses were devided by several owners.
