This research is to identify the relationship between land use and distribution patterns of vacant lots of large scale detached housing areas in Nagasaki-city, Nagasaki Prefecture, one of the provincial core cities, Japan. The main findings are as follows. (1) The ratio of total area of vacant lots in large scale detached housing areas is 16.8%. The ratio of total area of each land use (plot of vegetables, car park and unused land) in vacant lots is as follows; unused land; 89.7%, car park; 7.6% and plot of vegetables; 2.7%. (2) Blocks which include vacant lots are classified into 5 types based on following parameters (the ratio of total area of vacant lots in block, index of mixed land use, density of retaining structure and block in area). (3) The ratio of total area of plot of vegetables and car park in vacant lots of blocks which are low ratio of total area of vacant lots in block is higher than of blocks which are high ratio of total area of vacant lots in block. This is because vacant lots of blocks which are low ratio of total area of vacant lots in block is more commonly used by residents in comparison with blocks which are high ratio of total area of vacant lots in block. Based on these findings, we propose a list of considerations for utilizing vacant lots in large scale detached housing areas.
