Based on three case studies of social welfare facilities in proto-typical settings in a farm village, a town, and a city, we investigated how the facilities for persons with intellectual disability had been located and how they had been perceived and accepted by the local community. The following are results achieved by analyzing the diachronically receptive processes in case studies: 1) Employment opportunities which the facilities provided to the local people made it more easily receptive to people in the community. 2) The facilities played an important role of interacting with the local people in the local community. 3) The facilities tried to establish equal partnership with the local community. 4) Small group living was a key to reducing prejudice against persons with intellectual disability, and made people in the community more easily interactive under ordinary circumstances. 5) Reliable back-up supports were found to be essential in assisting independent living with persons with intellectual disability.
