Abstract
We figured out the conditions of sustainable management and inheritance of agricultural community which still has stabilized population structure in rural area. In terms of autonomy, inhabitants should have a chance to join the autonomous activity, not depending on their specific attribution. In terms of maintenance of living environment, the unit of the activity should be enlarged to decrease the charge of participants. In terms of agricultural management, elder and younger farmers should share the management depending on their advantages and the degree of dependence on farming. To reorganize the autonomy units in rural area, it should be multistoried by “Ooaza” units and ex-village units.
