This study analyzes through a questionnaire survey the influence of the farmland liquidation promotion program by an Agricultural Cooperative (JA) on its members' level of awareness and degree of using businesses the JA provides. JA Aichi Toyota is characterized by many farmers renting their farmland to two large scale agricultural corporations that have accumulated farmland supported by JA. The results indicate that, first, JA's business usage rate by members who do not cultivate their field is low. Second, the members who cultivate their paddy field for private consumption or only as an upland field use JA's business less than members who cultivate all fields. Third, the members who consulted with JA about leasing their farmland and requested JA to find a tenant farmer use JA's business are more than the members who found a tenant farmer by themselves or with the assistance of other institutions.
