The Multi-functionality Payment Grant aims to encourage large-scale rice farms through the direct payment of the wage for weeding paddy field levees although an impact verification is still required. Through the application of a mathematical programming model to a large-scale rice farm in Fukui Prefecture, we reached following conclusion. First, this direct payment scheme contributes to maintaining a farm business because a certain level of labor cost is provided. Second, raising the area-based payment rate does not lead to a farm scale increase because the payment indirectly supports the labor cost of field levee management. Third, the objectives of farms affect their field choice decisions when the direct payment is available in a limited geographical range. It should be noted that an excessive payment rate may hinder the conservation of less favored fields as the amount can be sufficient with a generous payment.
