The objective of this paper is to delinate the geographical region of feudatory of Hiroshima ruled by Asano family through Tokugawa shogunate era. Castle towns in Japan have been taken up as a typical planned city in feudal times. From socio-economic point of views in various disciplines and little attentions has been paid to spatial structure of its developmental processes. In this treatise, auther has tried to make clear major land-use patterns on block level and relevancy to occupation structure in Hiroshirna castle town in order to identify geographic region by showing a detailed intra-urban structure. For that purpose, auther reexamined various historical maps by map reading and fact findings were reduced to some geographical concepts as follows; 1) Castle istself and warrior's (Samural) quarter adjacent to it had been a pivotal center of feudal territory as weu as castle town through Edo era. 2) Merchant districts and its neighbourhood were divided into several parts by feudal lord. These districts were locally called machi-ju, exempt irom paying land rent. Merchant and artisan class, instead, was forced to pay in term of silver. Mairily because deltaic alluvial plain had to be expanded for further development policy-measures, the lord hammered out zoning scheme prescribing land use patterns, as 1) Core district comprising Castle, warrior's quarters, and merchant-artisan districts, 2) built-up area, in which newly established settlements adjoining to core district were included on the reclaimed deltaic flood plain. Land rent was levied after a few years since when new commers settled own in these district: Core district, built-up area and its adjacent arable lands on out skirts of the delta come under the jurisdiction of ad hoc administrative district, Iocally called Hiroshima-Fu. In conclusion, formal (administrative) region was critically scrutinized by applying category-wise occupa-tional composition, ratio of each blocks in each district and ratio of spatial contiguity to historical maps prepared in 17th to 19th. Feudatory of Hiroshima ruled by Asano family can be classified into four substantive regions as follows; 1) Core district of Castle town 2) built-up district of Castle town 3) ad-hoc administrative district 4) and finally Feudatory of Hiroshima (Asano family) Castle town

The purpose of this paper is flrstly, to reveal the regional structure of homogenous regions based on socio-economic characteristics and nodal ones based on work/school-trip flows by using multivariate analysis, and secondly to clarify the change in homogeneous and nodal regions of San-in region from 1965 to 1985. In investigating the long term change of non-metropolitan area, it is necessary to seek changes in structure of both regions. San-in region, composed of Tottori and Shimane prefectures as unit region on socio-economic activities was chosen as the study area because the district is separated from surrounding areas physically or economically and has peculiar regional structure. The main results are summarized as follows: 1) In order to clarify the changing features of homogeneous regions of San-in region, factor analysis was applied to the data matrix with 42 variables in 98 areas both in 1965 and 1985 (Table 1). The results of the analysis showed that five factors explaining 61.6% of the total variance were extracted in 1965 (Table 2). It is revealed that each factors are those of urbanity (explained variance: 30. Iolo), household/family status (14.8010), suburban agriculture (6.3%), work condition (5.6%), and manufacturing activities (4.8%). Similarly, five factors accounting for 63.2% of total variance were aiso extracted from the analysis of 1985 (Table 3), that is urbanity (25.2%), family/residential conditions (17.8%), agricultural activities (8.9%), population growih (6. 1%), and manufacturing activities (5.2%). The results of the analyses showed similar factorical structures for both years. We can also interpret that the first factor in 1965 was divided into the frst and second factors in 1985 (Fig. 7). 2) Based on the factor score obtained from factor analyses of regional characteristics each year, the writer classified them into elght groups respectively by using Word's cluster analysis (Table 5). 'Urban area A', 'urban are B', 'rural area A', 'rural area B', 'rural area C', 'rural area D', 'industrial area', and 'island area', are the classifications obtained from the analysis of regional characteristics in 1965. Sirnilarly, eight groups were found from the analysis of 1985, that is 'urban area a', 'urban area b', 'suburban area', 'further remote suburban area', 'agricultural area a"agricultural area b', 'island area a' and 'island area b'. In 1965, a wide area of the rural region was divided into suburban area and agricultural area. It is remarkable that the boundary of each groups coincided with the old country border (Fig. 8, 9). 3) The work/school-trip flows were synthesized by Q-mode factor analysis with 1 1 nodal regions in 1965 and 10 in 1985 (Fig. 10, 11). In comparison with 1965, the nodal regions synthesized in 1965 were enlarged although there was no fundamental change in the spatial pattem of nodal regions. In both years all together, the flows were mainiy oriented to central cities although there were a few of local flows whose destinations were not the central cities. Therefore, the structure of nodal regions of San-in region was sirnple one around the central cities.
