 note = {Isawa Plain is a fan having a 20km radius which was formed in the Diluvial Epoch, and its surface is mainly composed of fluvial terraces formed in there different levels, namely high, intermediate and low. The density of scattered farmsteads spreading on the whole area of the fan at present is high at the low level and relatively low at the intermediate and high levels. The development of arable land began in ancient times in the lower part of the level area, but that in the intermediate and high level areas belongs to later days, and in a part of the high level area, there are some places which were developed after the Second World War. Also the irrigation channels for paddy fields were mostly for those in the low level terrace area. Therefore, in the intermediate and high level areas and the upper part of the low level area, the proportion of paddy fields was low, and many fallow areas existed. At the end of the medieval period, the pattern of land utilization was still like this, and it hardly changed till the beginning of Meiji Era. Concerning Wakayanagi Village, which is located in the uppermost part of the low level area, the origin of the dispersed settlements and the structure of the settlements were elucidated. In Wakayanagi Village, the location of the settlements varies, such as the small village at the foot of a mountain and the isolated farmsteads spreading over the plain. By the analysis of the cadastres at the beginning of Edo Period and other materials, the individual family lines were investigated. The results are as follows :\ni) In Wakayanagi Village, there was no large increase in the number of houses throughout the Edo Period.\nii) In the small village at the foot of a mountain, among the peasant registered in the cadastres, some relations of the same family existed already at the time.\niii)  However, among the scattered farmsteads in the plain, no such related families existed. Afterward, by the creation of branch families, the relation of same family was born.\niv)  Among the isolated farmsteads in the intermediate and high level areas, which were newly reclaimed in the middle Edo Period, the mutual mutual relation to the same family has not existed.\nAs mentioned above, it is considered that the existence or not of the relation to the same family is related to the realization of the two forms, collective settlement and dispersed settlement.},
