Abstract
Recently in Japan, land consolidation projects are carried out by accumulating cultivation rights for the purpose of enlarging paddy field lots. Usually one field lot consists of many small-sized owner lots.
In these cases, it is feared that land owners will reject their lots to be substituted as lots of short frontage because they expect their lots to be converted to housing lots in the future. Moreover, this constraint of frontage of owner lots, it is also feared that field lots cannot be enlarged enough.
In order to clarify this constraint of frontage of owner lots, we investigated four study areas, that were the same in realizing large-sized paddy field lots by accumulating cultivation rights, but different in their potential of urbanization. Through this survey, we found many owner lots of short frontage in these areas that could not be used for housing lots individually. As a result, we showed that 1) in non-urbanized areas it is not necessary to substitute owner lots with frontage enough to be converted to housing lots individually, and 2) it is not necessary even in urbanized areas in the case where each owners cannot convert their lots to housing lots individually by geographical/ topographical conditions of the area.
