The purpose of this report is to find the dwelling realities of the aged residents by analyzing the relation between their behavior and time-use. Also studied were the placement and use of furniture as well as other life-supporting materials. The data used for our analysis are the results of the detailed investigation (1993, N =336) and the case study (1994, N =22). The living characteristics of the aged residents may be summarized as follows : 1) Half of the aged residents' basic living time (from getting up to going to bed) were more or less regular, but irregularity was seen in about 20% of them, especially in single males. Most of the single males had no interest in household work, with their dwelling behavior centering around visual and audio activities. 2) The basic living time of seniors and weaklings were rather regular, going out less frequently; leaving their residence happened only when going to hospital for treatment or going shopping to buy life-supporting necessities. It was also noted that their activities tended to become less while being unable to do household work positively. 3) The case study showed that half of the single household residents had their meals in WASITU or the Japanese style tatami-mat room and not in their dining-kitchen; they seemed to prefer YUKAZA or the Japanese style of dwelling. In so far as the physically handicapped residents were concerned, they used Western style beds for sleeping in WASITU.
