The paper reports on the result of research of the conditions about blank lots and empty houses in suburban areas located in Nagoya area. Many housing areas had been developed in 1960's to 1970'sthere. Nowadays, it is doubted that they are sustaining sociably and environmentally, because the population of most of all are deceasing. Some important facts are revealed through the research of 50 housing areas:(1) the average of ratios of blank lots is 14.3% in Kani and 9.5% in Tajimi,(2) the average of ratios of empty houses is 1.2% in Kani and 0.8% in Tajimi, lower than blank lots (3) Two of three blank lots are abandoned, but some areas use them as cooperative parking lots operated by communities to make up for the shortage of private parking (4) The relationship of the levels of dwelling environment and ratios of blank lots are found out partially (5) High ratios of blank lots does not necessarily mean declining of the areas by now. However some areas are rapidly decreasing the number of households, and then, the ratios of empty houses may be important indicator ofdeclining or un-sustainability of the area.
