This paper analyzes the current situation of seed potato production under farm size expansion, based on farm management data from town A in the Tokachi region of Hokkaido. Firstly are shown the trend of expansion of farm size, and the change in the planted area of potatoes in 2004 and 2021. Secondly, the production status of seed potatoes is clarified from the relationship between the agricultural management area and the planted area. As a result of that, it is found that although potatoes are a labor-intensive crop, the cultivated area is expanding along with the farm size. However, when focusing on seed potatoes, there is a limit to the expansion of the planted area.
