The sea vegetables wakame and nori has been a part of the Japanese diet since ancient times. Wakame is found on the Pacific coast of Japan anywhere south of the town of Muroran in Hokkaido, and on the Japan sea coast on the coast line of Hokkaido. Sanriku, Naruto and Izumo are particularly famous harvesting grounds for wakame. Most wakame is preserved, either by being dried or salted. It is often used as an ingredient in miso soup and vinegared salads called sunomono. Glutamate, an umami substance of wakame, is more abundant in wakame shoots than the leafy parts.
