This study aims to grasp the characteristics of 11 companies that embarked on agricultural business in Yabu, Hyogo, Japan, and to illuminate the requirements that enabled them to accumulate agricultural land. We analyze the relationship between type of business or scale of business and the size of cultivated area or intention to expand cultivated area in 11 companies interviewed in 2019. The results show that their selection of farm location was related to their potential to expand the scale of their farmlands after embarking on agricultural business. This study concludes that the requirement for a corporation’s entry and expansion of their area of operation after entering is that their type of farming be paddy rice, and the requirement for further scaling up of large-scale farm operations is the cooperation of the residents in maintenance work such as levee weeding.
