The article highlights the environmental challenges posed by Japan's practice of growing strawberries in greenhouses during the off-season, particularly in winter. This process, which involves using large heaters to maintain warm temperatures, results in greenhouse gas emissions that are approximately eight times higher than grapes and over 10 times higher than tangerines. The article follows Satoko Yoshimura, a farmer in Minoh, who reflects on the environmental impact of his heating practices and seeks alternatives. Despite the energy demands, the tradition of providing early-season 'hatsumono' strawberries, valued for their high price, continues to drive this energy-intensive farming practice.
