Salmon is the most popular item at conveyor-belt sushi restaurants in Japan, and demand continues to grow both domestically and globally. In response, Japan’s salmon farming industry has been rapidly expanding. Domestic production is projected to reach approximately 33,000–34,000 tons in 2026, up about 10% from the previous year and marking a new record. This growth is driven by both traditional sea-based aquaculture and the rapid development of land-based farming using Recirculating Aquaculture Systems (RAS).
In coastal regions such as Aomori and Hokkaido, sea-based farming remains a core production method. In the cold, fast-moving waters of the Tsugaru Strait, salmon develop firm flesh and rich fat content—qualities highly valued for sushi and sashimi. Companies such as Okamura Foods are leading this sector by introducing advanced Nordic technologies and large-scale farming systems. Working closely with local fishing communities, they produce branded fish such as “Aomori Salmon,” while expanding operations to include land-based hatcheries and remote-controlled feeding systems.
At the same time, Japan is seeing significant investment in land-based aquaculture. Pure Salmon Japan is developing one of the world’s largest RAS facilities in Tsu, Mie Prefecture, with a planned annual capacity of 10,000 tons. Other major players include FUJI ATLANTIC SALMON in Shizuoka, Atland (a joint venture between Mitsubishi Corporation and Umios) in Toyama, and FRD Japan in Saitama. These operations aim to produce high-quality salmon with fully controlled water conditions, reducing disease risk and enabling year-round production.
A defining characteristic of Japan’s salmon farming industry is its diversity of species and local brands. Farmed salmon in Japan includes a range of types, each with unique traits. Below is a detailed overview of major salmon species and brands:
| Species | Brand / Regional Name | Location | Farming Method | Estimated Annual Production (tons) |
|---|---|---|---|---|
| Atlantic salmon | FUJI ATLANTIC SALMON | Shizuoka | Land-based (RAS) | 4,700〜5,300 |
| Atlantic salmon | Atland | Toyama | Land-based (RAS) | 2,500 |
| Atlantic salmon | Pure Salmon Japan | Mie | Land-based (RAS) | 10,000 |
| Coho salmon | Kaikyo Salmon | Tohoku–Hokkaido | Sea-based | Not publicly disclosed |
| Coho salmon | Miyagi Salmon | Miyagi Prefecture | Sea-based | Not publicly disclosed |

Despite this growth, Japan still relies heavily on imports, with around 80% of its salmon sourced from Northern Europe and South America. However, global factors are reshaping the market. The Ukraine–Russia conflict has increased air freight costs and extended delivery times from Norway, while geopolitical tensions involving the Middle East, including Iran and the United States, have driven up oil and electricity prices. These factors not only raise import costs—already up roughly 60% over the past five years—but also impact domestic production, particularly energy-intensive land-based systems.
Each farming method presents its own advantages and challenges. Sea-based farming allows for large-scale production and natural growth conditions but is vulnerable to environmental risks such as red tides and disease. Land-based RAS systems offer precise control over water quality and eliminate marine pollution, yet require substantial capital investment and high energy consumption. Hybrid systems, in which fish are raised on land before being transferred to the sea, provide a balance between efficiency and quality but add operational complexity.
Looking ahead, Japan’s ability to establish itself as a major salmon-producing nation will depend on how effectively it integrates these approaches. Expanding branded domestic production, improving energy efficiency, and leveraging technological innovation will be essential. At the same time, imported salmon is likely to remain important for premium markets, while domestic farmed salmon increasingly supports local demand.
In this evolving landscape, Japan’s salmon industry is shifting from import dependence toward a more diversified and resilient production model—one that combines regional identity, species diversity, and advanced aquaculture technology.
