A seaweed belonging to the brown algae family Laminariales. The algae consist of a well-developed stalk and a leaf attached to the top. The stalk is perennial, hard, cylindrical, and significantly branches at the bottom to form a rhizoid that attaches to the bedrock. The leaf branches bifurcates and then pinnates to form numerous leaflets. Those that grow at depth can reach a total length of 1.5m. It is widely distributed throughout Honshu, and can form large colonies from the lower intertidal zone to the low tide line. In some areas, it is edible. It is also a source of alginic acid.
