Agricultural activities in Japan have been limited to the aging and diminishing labor force, as well as the small plots of cultivated land in mountainous regions. Therefore, smart agriculture has been launched to ensure food security in Japan. A systematic framework has been provided to support the digitization of forestry and aquaculture, including the basic Law and national strategy. Numerous technological innovations have also involved machinery automation, information systems, rural network transformation, agricultural aviation, and plant factories. Modern agriculture has allowed the 1 404 000 core farmers and the majority of the elderly population to achieve nearly 130 million people self-sufficient in the major food. Among them, the Japan Agricultural Association has played a pivotal role in this transformation, covering the various processes at multiple levels and departments. These fundamental facilitates have provided crucial support to implement smart agriculture. This study aims to analyze the trajectory and efficacy of smart agriculture in Japan. The valuable insights were then obtained for the several suggestions. Firstly, it was very necessary to innovate the agricultural system and mechanism, in order to create the channels for the seamless circulation of information, manpower, and resources. The agricultural environment was sustained to leverage the strengths of diverse entities, such as local governments, universities, and enterprises. Long-term empirical research was performed on smart agricultural technology in rural revitalization. These insights should be adapted to the local conditions in the agricultural production, sales, promotion, and management from the Japanese Farmers' Association's experience. The findings can greatly contribute to the revitalization of rural areas in China. In turn, the trajectory of rural modernization can be accelerated to position as a formidable force in the realm of smart agriculture. These lessons can also be incorporated into sustainable and technologically advanced agricultural systems. [ABSTRACT FROM AUTHOR]

Rural revitalization strategy is a hot topic in China. How to ensure the steady advancement of rural revitalization strategy and its effect of rural revitalization needs to evaluate the level of rural revitalization. Therefore, Construction of a scientific and reasonable evaluation index system for rural rejuvenation level is of great significance for the monitoring and evaluation of rural rejuvenation level. This study uses five aspects indexes of prosperity of industry, ecological livability, rural civilization, effective governance, and wealthy life to construct a evaluation index system of rural revitalization level based on statistical analysis of the evaluation indexes in the literature and frequency analysis, combined with expert consultation and field surveys, and the indexes are comprehensive grain production capacity; agricultural science and technology progress contribution rate; agricultural labor productivity; proportion of agricultural mechanization; level of agricultural informatization; village green coverage; waste treatment rate; rural sanitary toilet penetration rate; days of air quality compliance;percentage of expenditure on education, culture and entertainment of rural residents; average years of education of rural population; proportion of full-time teachers with bachelor degree or above in primary and secondary schools; village affairs open rate; rural gini coefficient; rural governance villager participation rate; income ratio of urban and rural residents; engel coefficient of rural residents; and per capita disposable income of rural residents. An empirical study is carried out with 5 towns (Anzhuang, Wangzhuang, Taoyuan, Wenyang and Sunbo) in Feicheng City, Shandong Province. The weight of each evaluation index for the evaluation of the rural revitalization level of each township is determined based on the analytic hierarchy process and Delphi method. A comprehensive evaluation method is used to establish an evaluation model of rural revitalization level and calculate the rural revival level index of each township. The rural revitalization index of Anzhuang Town, Wangzhuang Town, Taoyuan Town, Wenyang Town and Sunbo Town are 0.850 7, 0.848 8, 0.844 2, 0.811 2, 0.781 0 respectively. Anzhuang Town, Wangzhuang Town, Taoyuan Town, and Wenyang Town have a relatively high level of rural revitalization. The rural revitalization level of Sunbo Town is lower than the above 4 towns and needs to be improved. In the context of the implementation of the rural revitalization strategy, the research on the evaluation indexes and models of rural revitalization level is not only important for scientifically measuring the level of rural revitalization, but also for monitoring and early warning and correcting the level of rural revitalization, and it would play a positive role to promote the implementation of strategy.
