This study examines four key aspects of stable oilseed procurement, providing insights into the overall structure of the rapeseed food system imported from Canada to Japan. Firstly, we present an overview of the current situation and challenges associated with the procurement of imported rapeseed in Japan. Secondly, we clarify the vertical coordination system, shedding light on potential future access to rapeseed export channels from Canada. Thirdly, we analyze the decision-making process for determining optimal quantities of imported rapeseed and explore alternative options. Lastly, we examine power imbalances within the vertical stages of the rapeseed food system from an equity perspective. The study concludes with policy implications as follows: (1) Under a trading structure with price mechanism functions, it is necessary to create an environment in which the Japanese vegetable oil industry can pass on high raw material prices to consumers to ensure competitive and stable raw material procurement; (2) It is essential to establish stable and close political relationships between countries; (3) When considering alternative oil and fat products, confirming Japanese consumer evaluations is necessary; and (4) Since the expansion of biodiesel production in various countries could be detrimental to Japan's food security, its merits and demerits must be evaluated.
