The Uni Ranch® ensures sustainable and stable production and shipments.

The four-year sea urchin production at the Hirono Sea Urchin Ranch is carried out in a four-year cycle, from raising young urchins, releasing them into the sea, raising them on the ranch, landing them, processing them, and shipping them out.

By strictly managing the rotation from production to shipping, we have realized a sustainable sea urchin fishery that never catches all the sea urchins.
