Uni Story

Located on the Pacific Coast and north of Los Angeles, Santa Barbara is a major production area blessed with high quality wild red sea urchin.  Cold current from North and abundant sea kelp help sea urchin grow larger and sweeter.  Once sea urchin is unloaded at the Santa Barbara port, immediately moved to the factory in Long Beach and processed on the same day.

Leaving from Santa Barbara & San Pedro Port

Before the sun rises, Maruhide contracted divers leave either from Santa Barbara or San Pedro port.  They will find a best spot for harvesting sea urchin, using their experience and knowledge about ocean water temperature, current flow, season and feed circumstance, etc.

Harvesting “Red Sea Urchin”

Divers dive to the depth of more than 32 feet and pick red sea urchin one by one, using special tools.  Red sea urchin sometime reaches 7 to 8 inches in diameter.
