This paper investigates variability of farm income and revenue on upland farms in the Tokachi district. The main results are as follows. First, variability of farm income, revenue and agricultural products sales differs depending on type of farming and farm size. Variability on vegetable farm entities is larger than on single dry field farm entities. The larger the farm size, the larger the variability is on single dry field entities. Second, there is a correlation between the coefficient of variation of agricultural product sales and the coefficient of variation of revenue. But there is also a weak correlation between the coefficient of variation of agricultural product sales and the coefficient of variation of farm income. Third, under stable management, the marginal profit rate is higher and fixed cost is lower than under unstable management.
