We surveyed and analyzed the condition of land uses in 80 neighborhoods which Japan Housing Coorporation is managing in Tokyo, Kanto, Nagoya and Kyusyu, and computed the rate of each land use. Total area which except outside roads, waterways, and unused land from the purchased area, was distinguished between public roads, roads, parks, land for community buildings, land for common utilities, and land for residential buildings. Moreover, park was distinguished between playground and common space; common space between open space, side green, separate green, slope and pond; land for community buildings between land for assembly hall, manazing office, shops, post office, and clinic; land for common utilities between land for water suply, purification tank and gas governer; and land for residential buildings between aproach, building area, and garden. Those areas were measured by the proportion of weight. As a result, the area of each land use in 80 neighborhood is indicated 1st table in this report. Some of those main consequences follow; 1) Gross coverage of building in flat groups is 15.53 per cent. 2) Net coverage of building in terrace groups is 36.7 per cent. 3) Area of roads is relatively greater and road coefficient (length of roads/length of building frontage) is 1.57 in flat groups, but is 2.14 in terrace groups. 4) Although area of playground is 5% of total area, those layout is not sufficient to utilize. 5) In general, common space is 20% of total area in flat groups and 30% in terrace groups. 6) Land for purification tank is 0.27A1/2 (A is total area).
