This paper conducted cross-sectional and panel census data analysis from year 2005 and 2010 in addition to factor share analysis to consider the regional differences that impact farmland consolidation in three areas of Japan, namely Tohoku, Hokuriku, and Kinki. First, the characteristics of each area indicated differential influences on the performance of the land consolidation policy. Second, organized farm management bodies such as village-based farming organization approved by the government also had positive impacts on farmland consolidation. The results of factor share analysis indicated three points. First, the effect of the number of Non-farmer with farmland ownerships had highest share in all areas. Second, the impacts of regionally differential characteristics on farmland consolidation had individual characteristic effects of municipality and time effect such as Kinki has high contribution rate of farm-work contract farming management body in panel data than cross-sectional data. Third, the factors that characterized the problem of each area showed higher effect on farmland consolidation. The government needs to consider regional differences when making decisions on farmland consolidation policies. . Acknowledgement :
