Since the 2000s,compared with other countries,the rates of annual increase for Japanese rice,wheat,barley and soybean yields have been low. Stagnation of land productivity is a serious problem in Japanese paddy farming. On the other hand,the rapid expansion of corefarmers'farrnland is expected. In these circumstances,new farming technologies which utilize Information and Communication Technology,Robot Technology and Artificial Intelligence,so-calIed“smart agriculture" are expected. However,those technologies themselves do not convert the cultivation technology. Therefore,for the improvement of land productivity,it is necessary to develop a new cultivation system with the utilization of smart agricultural technologies.
