This paper attempts to understand the thoughts of the farmers and other residents in the Minamiyama area of Inagi at the respective time, taking into consideration the long history of development planning, changes in the use of land, and the land readjustment project that has been underway. Local farmers sold land in Minamiyama, operated real estate businesses, Land readjustment brought about by the City Planning Act helped the farmers.

Land is a non-renewable resource with limited availability and, therefore, a very important issue is the preservation of useful properties of land and comprehensive and sustainable land use. The process of land and soil degradation (decline of properties) leading to the formation of degraded land have been observed due to the influence of various economic activities and environmental conditions.
