Green glass Japanese fishnet float. These floats were used for fishing by the Japanese as well as other peoples living around the South Pacific and in the various island groups in the Western Pacific. Most of the fishing fleets, ranging far from their home ports, carried the raw materials to make glass and manufactured these floats as they were needed, and when returning home with the catch would throw them into the sea. These floats would drift sometimes for years until the Japanese current caught them, bringing them into the North Pacific Ocean and then down the coast of North America, and then caught on the incoming tides. These floats were picked up on the Washington coast around Westport.
