Japan's demand for imported dried seaweed is increasing due to a decrease in domestic production, leading to a rise in prices and a shift towards imported seaweed, particularly from Korea. Despite rising prices, Korean seaweed maintains price competitiveness and is preferred by Japanese consumers. The Japanese government plans to increase the import quota for Korean seaweed from 1.2 billion sheets in 2015 to 2.7 billion sheets in 2025. Additionally, a Food Safety Management Certification Standard (HACCP) will be mandatory for imported foods in Japan from June 2020, emphasizing the need for proper inspection, management, and safety in the exporting country. Maintaining quality, stable supply, and price are crucial for Korean seaweed to remain competitive in the Japanese market.
