The two-storey wooden houses in Naha city played an important role in the urban formation after W. W. II. The concentration of these houses indicates the process of rebuilding of Naha city in early post-war period. As one of the typical urban dwellings, the two-storey wooden houses formed high-density residential communities and were used multifunctionaly. The first floor was usually for shops and the second floor was for residential uses. The renewals of these houses are difficult because of the complication of tenure for the land and for the buildings.
