Known in Japan as fueru wakame or 'expanding wakame', the product contains nothing but finest top quality wakame, which is a brown sea vegetable with the Latin name Undaria pinnatifida. The flakes are made by a simple process where the wakame is blanched for a few seconds before being dried & packed. The wakame itself is cultivated on ropes & harvested on the Sanriku coast of northeast Japan, which is renowned as an area of quality wakame production. The wakame spores are sown in June or July. Eight months or so later in March the microscopic spores have grown to become fronds anywhere between 1.3 & 2 meters in length, which are then harvested from their ropes.
