The effect of farmland accumulation by “large-scale business farms" decreases with the expansion of the farmland and with decentralization advances.We administered a questionnaire survey on leased land choice and found that for farmers the distance from existing cultivated land or their homes is important. They do not prioritize how to grow better crops. Then, we calculated real-time location information data using GPS. A comparison of transplantation and direct sowing showed an improvement of 45% in direct sowing with regard to work efficiency.The factor has improved by the shortening of 17% of the travel time between fields. In conclusion, large-scale business farms give importance to distance and not the yields or breeding of crops. This result has been demonstrated by significantly lowering the efficiency of the agricultural field by moving the waste of time.
