This study deals with the market trend analysis of major polysaccharide materials(chitosan, hyaluronic acid, chondroitin, ßglucan, fucoidan and glucosamine) in Japan. We analysed market trend in Japan in order to prospect the technology and market trend in Korea as Japan is a world leader in this field. Most of polysaccharides were used as an additive to health functional food, cosmetics or medical product.
