1 Recently, in the suburbs of cities, disorderly land use which is caused by the confusion of urban and rural landuse is becomming a serious hindrance to the maintenance of environment for settlement or agriculture, and for the establishment of land-use planning.
2 To put down the confusion, the new law carried out at June 1987. The law is composed of two parts. One of the parts is the local settlement plan, and the other is the agricultural community development plan.
3 The important pointsof view for contents of the new law are following;
·the contents of the new settlement area adjustment utilities.
·the new adjustment system for urban and rural land-use.
·the relationship of masterplan and districtplan.
·the balance fof the control of buildings and the intention of inhabitants.
·the neutralizing measures of the development permission standard.
·preservation of villagescape.
4 The main subjects of the rural land-use planning are following:
the structure of planning-stage for land-use plan.
the new ideas of the settlement area adjustment utilities.
the control of land-use and the flexibilty of plan.
the method of the planning for new settlement and community.

Land use planning that considers a city and suburban agricultural villages as one to comprehensively plan various environments does not exist in Japan. The master land use plan, which is a master plan for the utilization of land, has limits especially for suburban district planning because of imperfect consolidation of individual regulations and laws. Individual regulations and laws, such as the urban design law and other similar laws, are wanting in comprehensiveness. They show only the relative land use division from the standpoint of urbanization or restriction of urbanization and most are not based on actual conditions.
The reason is a lack of understanding of the dynamic state of land use in suburban districts and delays in the consolidation of land use planning to reflect changes.
In this study, which uses the Chita area in Aichi Prefecture as an example, the actual land use conditions in suburban districts are analyzed with land use and land use planning that reflect actual conditions.
First, the purpose and method of land use analysis were described. The final object of the analysis is to identify transition areas that are urbanized in terms of land use. The division of land use in the Chita area was made using a time series urbanization scale. Second, the result of the analysis was described. In the Chita area, the area predicted to become a city area will reach approximately 50% of the entire area. Almost all the areas were shown to be located in the urban control area, but not always within the boundaries of the existing town and city. Third, based on the results of the analysis in the Chita area, a study was made of what the land use division and planning in future should be. Judging from the actual conditions of land use, it will be desirable to develop at the village, town or area level an overall land use plan. In order to assure success of the plan, it is absolutely necessary to extract the transition area and free them from urban and agricultural village division, and then implement the plan selectively

The social organization in Thai village is highly conformable with the concept of social networks: in Thai village, independent villagers form networks of consummatory social relationship in order to secure one's existence.
By the way, a survey report shows that, in northeastern Thai villages, incidental modernizing influences, e. g. urbanization, had led to economic heterogeneity within the village, but the disparity was increasing only because of the difference in rateof progress among villagers. The characteristic of social organization can rationalize this finding.
First, there are not any social groups which put a curb on a villager's activity. So the rise in income is bacically a private affair. Therefore the increase in economic disparity might be an inevitability.
But second, the “social networks are established on the premise that each person is “independent”. So even when individualistic activities has been actualized in changing economic environment, the social networks among villagers might be maintained.
Then the increase in economic disparity shows the pattern described above, because the social networks function as a channel of information and loan.
The validity of above rationale is supported by the findings from Don Daeng village and its vicinity in Northeast Thailand. The survey results consist of three parts: (1) . precondition: villager's life under subsistence conditions, (2) . economic changes after 1960 s, (3) . maintenance of social networks among villagers.

Economy has been developed to a high degree in postwar Japan and it was a turning point in the industrial structure. Agriculture and forestry in Japan also has undergone a remarkable change through various markets surrounding them. In marginal land or depopulated region public investiment was lacking before and after the war. In addition to this energy revolutionidependance of imported lumber and decline of farming department caused the decay of conventional industry. As laber market in cities expanded an outflow of population became more and more conspicuous. In this way farmlands which lost their undertaker have been decayed in retreating situation of regional agriculture. On the other hand some farms has grown utilizing such situations. This paper intends to analize developing process of these farms historically from prewar period.
