Abstract: Japans’ agricultural product market started early, with substantial hierarchy and coordination, which can provide valuable implications for China in constructing a unified domestic agricultural product market. This article reviews the evolution process and system composition of Japan‘s agricultural product market, and summarizes its practices and policies in building a unified national market. Research has shown that the construction experience of Japan’s national unified agricultural product market includes establishing a relatively complete legislative system, achieving close integration with the administrative management system through location and function integration, constructing a unified and coordinated market operation standard, mechanism and organizational system, implementing a series of investment and financing guarantee projects to ensure market standardization, and promoting information and communication technology to promote communication and integration between markets. At the same time, attention should also be paid to preventing problems such as high operating costs, lagging infrastructure, and slow price formation in wholesale markets, which can lead to sustained decline in utilization rates.

Key words: agricultural product, market circulation, a unified domestic market, central wholesale market, Japan
