Major applications: as sushi nori (the defining application — maki-zushi, temaki, onigiri wraps; nori sheets are essential to global sushi cuisine), as yaki-nori and ajitsuke-nori snack retail (major Japanese household and gift category), as soup/udon/donburi garnish (kizami-nori shredded format), and as functional food positioning (high iodine, vitamin B12, dietary fiber). Ariake Sea (Saga/Fukuoka/Kumamoto/Nagasaki) is the volume domestic production region (over 50% share); Seto Inland Sea regions provide premium specialty; significant Korean and Chinese imports supply cost-positioned mass-market.
