At the same time, the effectiveness of direct payment for hilly and mountainous areas is examined. In view of the changes in agricultural management and land use, agricultural trends in the study area are divided into two periods. In the first period to the end of the 1980s, tree planting was conducted due to the rice production adjustment and mechanization of agriculture. In the second period from the 1990s, the retirement of principal farmers from agriculture increased and accelerated the expansion of cultivation abandonment. Although borrowing and lending of cultivated land increased in this period, they were not sufficient to prevent cultivation abandonment. The direct payment plays a certain role in sustaining agriculture. However, it has room for improvement in the area designation. Key words: abandoned cultivated land, hilly and mountainous areas, marginal hamlet, direct payment for hilly and mountainous areas, farmers decision making, Minamata city 603
