The price of Japanese and South Korean green onions has surged due to a combination of factors including harsh weather conditions, climate change, reduced planting areas, and the new coronavirus epidemic. The most significant increase was seen in March, with Japanese green onions from China costing 375 yen per kilogram, a 2.4-fold increase from the previous year and the highest price since 2004. In contrast, Chinese green onion prices have already dropped by 16-30% due to an increase in production in key regions and the normal aging of the crop, which reduces its market value. The article anticipates further price drops as spring temperatures foster green onion growth, potentially returning prices to normal.
