Edamame is a green soybean that is rich in nutrients. Boiled edamame has traditionally been used as a food in the East Asian region. Farmers have known that conditions such as temperature and climate on the day of harvest affect the quality of edamame. Large-scale farmers harvest edamame on several days in the same year; however, the quality of edamame varies from day to day due to variations in climatic conditions. In this study, we harvested edamame on multiple days between 2013 and 2018, obtained the climate conditions on the day of harvest, and performed metabolomic analysis using capillary electrophoresis mass spectrometry. To clarify the correlation between climate conditions before the harvest date and edamame components, comparative analyses of the obtained meteorological and metabolomic data were performed. We found positive and negative correlations between sunshine duration and mean temperature and the amounts of some edamame components. In addition, correlations were observed between annual variations in climate conditions and edamame components. Our results suggest that climatic conditions before the harvest date are closely related to edamame quality.
