    Condominiums are increasing in metropolitan areas of Japan. As a matter of fact, they are taking up important part among residential houses. Studies on these comdominiums started to appear in the latter of 1970s, which mainly focused on construction process or attributes of dwellers. Few, however, took up their prices, which probably is due to insufficient statistics covering residential houses. In this paper, therefore, most emphasis is placed on clarifying locational characteristics of condominiums by analysing the relationship between "floor space index (hereafter referred to as FSD" and "unit price per m^2 (hereafter referred to as UPPm^2)". City wards of Nagoya have been chosen as unit for analysis here (Fig. 1) and data used in this paper are taken from "Condominiums list all over Japan" issued by the Institute of Real Estates and Economics (Fudosan Keizai Kenkyujo). The process and the result of this study may be summarized as follows; First, the author studied on how location of condomoniums have changed (Fig. 2, Table 1). Secondly, we divided the city wards into several groups according to FSI deviation' (Table 4, Fig. 3). Then we devided them differently according to UPPm^2 deviation (Table 5, Fig. 4). Studying the relationship between FSI diviation and UPPm^2 deviation, we came to another area division (Fig. 5, 6). Cluster analysis using the data of Fig. 5 is shown as Fig. 7, and areas common locational characteristics are classified into next 5 groups (Fig. 8). Cluster [○!a]: Only Naka Ward belongs to this group. In spite of the highest land prices, condominiums here are supplied at less expensive price level (ranking at 4th among other). This is due to less strict FSI regulations. Cluster [○!b]: Only Higashi Ward belongs to this group. Compared with Naka Ward, land prices here are cheaper, while FSI regulations are more strict. This is the reason why Higashi Ward could not supply condominiums with FSI as high as it is in Naka Ward. Price level, condominiums here are cheaper than those in Showa Ward and Chikusa Ward, which as the result makes its FSI look attractive enough. Cluster [○!c]: Consists of Showa Ward, Chikusa Ward, Mizuho Ward and Meito Ward. Condominiums in these wards are characterized by low FSI and high price levels, caused by high land prices and strict FSI regulations. Cluster [○!d]: Belonging to this group are Nakamura Ward, Atsuta Ward, Nishi Ward and Kita Ward. Probably due to having inner cities inside, land prices in these wards are relatively low, showing low price and high FSI characteristics. Cluster [○!e]: Consists of Tempaku Ward, Midori Ward, Moriyama Ward, Nakagawa Ward, Minami Ward and Minato Ward. Relatively low land prices are the characteristics they have in common.

    The Sea of Ariake is the bay that has the greatest tidal range in Japan and has some vast tidal plains. Investigations in the previous studies on transformation of land and sea breezes were discussed only in terms of synoptic scale wind and orographical effects. Tidal wind, which blows in accordance with the ebb and flow, is said to be observed on a calm weather, however the effects of tide on land and sea breezes were not known. The purpose of this paper is to describe the general characteristics of land and sea breezes in the summer period on the Tukushi Plain that faces the Sea of Ariake, and to clarify the tidal effects on land and sea breezes. The Tukushi Plain is surrounded by hills on three sides, and two valleys run the northwestern and northeastern parts of the plain (Fig. 1). The results obtained in this study can be summarized as follows: 1. Sea breeze starts earlier in the seashore area by one to two hours than on the sea and in the inland area (Fig. 3). 2. In the Tukushi Plain, breezes of two different direction can be seen in the evening and night. They blow parallel to the two valleys along NW to SE and NE to SW direction, respectively. Northwesterly wind comes to blow around 4 p.m. and northeasterly land breeze prevails in the middle of night (Fig. 4). 3. With regards to the tidal effects on land and sea breezes, it was found that northwesterly which begins to blow in the evening is transformed in accordance with a tidal cycle (Fig. 5 and Fig. 6). In the north coast of the Sea of Ariake, evening westerly from northwestern valley is stronger prevails at flowing period than ebbing period. On the contrary, southerly prevails at flowing period and westerly appears at ebbing period on the sea. Therefore, it can be concluded that the path of northwesterly from northwestern valley migrates northward or southward in accordance with flowing or ebbing of tide (Fig. 7).
