The population continues to grow,
and consumption of marine products continues to increase.

Natural fish catches have already reached their peak,
and marine aquaculture is rapidly expanding around the world.
As a result, the environmental impact of fish droppings and leftover feed is becoming an
increasing problem.

To leave delicious fish and beautiful nature to the next generation.
What we need now is land-based aquaculture that does not depend on the sea.

We, FRD Japan, will create a future where freshly caught, safe and secure fish can be produced
anywhere in the world using a Closed RAS system.

Land-farmed raw salmon from Chiba Prefecture

OKASODACHI island-cultured fresh salmon from Chiba Prefecture.

OKASODACHI is a sustainable, antibiotic-free, ASC-certified, and earth-friendly salmon.

OKASODACHI realizes the compatibility between human society and the natural environment from the perspective of fish.

// our technology

A Closed RAS system realizes a sustainable future for food.

FRD Japan’s Closed RAS system uses a unique filtration technology that utilizes bacteria.

It makes it possible to conduct aquaculture while circulating artificial seawater made by tap water instead of seawater or groundwater.

Zero drainage to the sea and rivers

Earth-friendly culture methods that do not pollute oceans and rivers.

No need for seawater cooling costs

Dramatically reduces electricity costs, which have been a bottleneck for land-based aquaculture.

It can be cultured "anytime, anywhere."

Delivery of the freshest fish all year round from the suburbs of consumption areas with minimal transportation costs.

No risk of fish diseases from seawater

Enables stable production without the use of antibiotics.
