Since the 2000s, black tea production has been increasing in Japan, including in Okinawa, which is one of the most noted areas in Japan for excellent black tea quality. The authors highlight the production and supply chain structures of black tea producers, focusing on their management and technological adoption. Tea farmers in the study area are classified two types: those who remain centered on green tea production; and those who have improved their technology so that their products can be classified as premium black tea. The former continue to adopt technologies shaped by green tea production experiences and utilize supply chains secondarily used for the sales of green tea. The latter, however, have developed cultivation and processing technologies tailored for black tea production, relying on refined skills instead of the introduction of labor-saving devices. In terms of sales, the latter have developed new supply chains to create appropriate brand images of their products. Given that market conditions for budget black tea have not yet been established in Japan, the former group of tea producers will likely make the transition to the production and supply chain management styles adopted by the latter group.
