Oysters are easily shucked without using a knife! Because unwanted matter is never mixed in the shucking process, oysters are always delivered safe and secure!

KUNIHIRO is Japan's No.1 oyster the biggest company by volume. We handle nearly 5,000 tons of oysters a year. Our skilled staff rigorously inspects and carefully selects the very best in oyster quality and shape we are confident defines good taste. The tough standards we expect and demand from our inspection system ensures that each oyster is delivered to each of our customers with safety and security in mind and a sensation of deliciousness.



Harvest

Oysters suspended from oyster rafts for more than one year fatten up and the large fully-flavored oysters are harvested in mid-winter.

Raw Materials Incoming Acceptance Inspection

Oysters are inspected by a third party inspection agency registered with the Ministry of Health, Labor and Welfare, and we accept only oysters that meet our voluntary standards.

Purification Work

Bacteria and foreign objects, etc., are removed from oysters using 100% artificial seawater free of norovirus. Oysters are purified and nurtured at a proper seawater temperature to accelerate purification and stabilize quality.

Low Temperature-High Pressure Processing

By low temperature-high pressure processing, the adductor muscle is separated from the shell to enable the oyster to be opened easily. Without being heated, oyster meat is not denatured, leaving the meat almost entirely raw.

Shelled oysters can be easily opened at a depth of tens of thousands of meters.

Conventionally opening oysters required professional skill and experience, but through the development of low temperature-high pressure processing and our proprietary processing method to apply water pressure which is much higher than water pressure applied at the bottom of the Mariana Trench (water depth: 10,000m), the deepest location on earth, we have made it possible to open oysters easily without using a knife.

Quality Control

We are the only private company that has highly established a system to conduct a "norovirus inspection." In addition, we also implement a strict inspection system and quality control such as a "shellfish toxin inspection" and a "bacteria inspection."
