Title : Ariake Sea
Nori farming in the Ariake Sea is carried out using a unique aquaculture system known as the “pole system,” in which large numbers of poles are planted in the ocean with nets hung between them. Intrinsic to this system is the difference between the ebb and flow of the Ariake Sea’s tide, which, at a maximum of six meters, is one of the greatest in the world. At high tide, the nori is submerged in the ocean water, allowing it to take in nutrients from the sea; at low tide, the nori rises above sea level and basks in the sun’s rays, making it more flavorsome. This cycle utilizes the power of nature to create delicious nori.
