The largest climate benefit of our planned production is avoiding the transport of salmon by air from Europe to Asia. Around 90 % of fresh salmon consumed in Japan is transported by air from Norway. Land-based aquaculture also eliminates the use of boats for feeding and harvesting, thereby reducing the use of fossil fuels.

Energy efficiency

We have chosen a Recirculating Aquaculture System (RAS) from AquaMaof with significantly lower energy consumption than other conventional RAS solutions available in the market.

Energy supply

We are working on different solutions for installing a rooftop solar PV system on our main building. The solar panels will be designed to meet our electricity demand during peak production hours. Excess generation will be sold to the grid. We will purchase certificates of origin to ensure that all purchased electricity is derived from renewable sources.

Water use and wastewater management

The AquaMaof system can recirculate 99.7 % of the water by efficiently removing nitrate and nitrite, resulting in a low wastewater volume by using  a denitrification system which reduces the amount of sludge and need for replacement water.

Waste management

Trimmings and by-products are due to be processed where possible into products for human consumption, with the remainder considered for pet food or refined into fish meal and oil. We intend to reduce the amount of packaging and non-organic waste to a minimum, recycle and have the ambition to use recycled materials in packaging where feasible.


Our selected feed supplier, Skretting, has a factory in Japan which will minimize emissions associated with transportation of feed.  Skretting is sourcing soy and oil palm ingredients either from Low risk regions or from High risk regions with certification verifying no illegal deforestation has occurred. By the end of 2025, they are committed to only sourcing soy and oil palm ingredients from Low risk regions or from High risk regions that are free from legal and illegal deforestation, in fully segregated physical supply-chains under third party certification schemes.

Our Atlantic Salmon is born, bred and consumed in Japan

Atlantic Salmon at a Glance

The Atlantic salmon, originating from the northern Atlantic Ocean, thrives in cold, pristine waters of rivers and oceans. While historically abundant in these habitats, the vast majority of  Atlantic salmon consumed today is farmed.  Major cultivation hubs include Norway, Scotland, Canada, and Chile, meeting the demand for this esteemed fish.

Renowned for its robust taste, firm flesh, and ample Omega-3 oils, Atlantic salmon offers versatility in culinary creations. Its rich, red flesh elevates dishes, from gourmet delicacies to everyday meals, making it a prized catch worldwide.

Salmon in Japan

The history of Atlantic salmon in Japan intertwines with its culinary evolution. While not native to Japan, Atlantic salmon has gained prominence due to its versatility in sushi and sashimi. Initially introduced to diversify seafood offerings, its popularity grew, leading to imports primarily from Norway and Scotland. Today, it remains a sought-after ingredient in Japanese cuisine, symbolizing the fusion of global tastes in traditional Japanese dishes.

Our Salmon Production

Proximar receives eggs on a monthly basis from the renowned StofnFiskur strain on Iceland. These are hatched, nursed and farmed at our facility by the foot of Mount Fuji, using locally manufactured feed. The top-tier operational team consists of both locals and international industry experts.

With our phase 1 facility, we will at steady state harvest around 5 300 tonnes of head-on-gutted Atlantic Salmon every year. We plan to harvest at least five days every week, ensuring delivery of day-fresh products to our customers. The fish will be distributed through our partner Marubeni.
