Junsai (water shield) is a delicate summer delicacy — a jelly-coated aquatic plant hand-harvested from ponds by wooden punt in Mitane, northern Akita, which produces most of Japan’s crop. Prized for its silky, slippery texture and clean taste, it’s served chilled with vinegar or dashi, in miso soup, or in hot pot. Some farms offer summer harvesting experiences by boat.
