In this study, we analyzed the characteristics of family farm management and agricultural labor force from the perspective of family structure based on the 2005 to 2015 Census of Agriculture and Forestry. Our results are summarized into five points, as follows. First, regarding the family structure of farmers, the number of three-generation households has decreased drastically in all areas, whereas the number of single-generation households has increased. Second, multi-generation household farmers own a large proportion of leased farmland. It became clear that the behavior of farmers lending farmland is closely related to the family structure of farmers. Third, there is no relationship between the family structure of farmers and leasing behavior of farmland. From 2010 to 2015, except for some areas such as Hokkaido, farmers are leasing farmland regardless of family structure. Fourth, the number of family farms with medium-sized agricultural labor force has markedly decreased from 2010 to 2015. One reason is that due to the aging of household members, the number of three-generation family farms has decreased. Fifth, since 2005, the number of employed full-time workers has increased. Employment labor force in Hokkaido accounts for more than 20% of the total labor force. Training human resources to work in farms is important in agricultural management.
