The Merits and Origins of Salmon in Japanese Sushi

Once a staple of river fishing, salmon was not a sight in sushi restaurants due to its cold-chain requirements and historical dietary customs. This article explores the historical and cultural reasons why salmon sushi remains uncommon, despite its ubiquitous presence today. From traditional sushi to modern sushi trends, understand why salmon was not considered for sushi until recently, and how the industry has changed over time.

The Historical Context of Salmon in Sushi

For centuries, before the advent of cold-chain technology, salmon was a deeply salted and preserved fish, sold away from its natural fresh environment. Salmon, known for parasitic risks when consumed raw, has a life cycle that requires it to migrate from the sea to rivers for breeding, making it an unsuitable and potentially dangerous choice for sushi.

Advent into Modern Cuisine

Despite the history, today, salmon sushi is a common sight in many sushi restaurants worldwide, but its journey to this status is a story of modern innovation and cultural exchange.

Traditional Edomae Sushi vs. Salmon

The roots of sushi lie in the traditional Edomae sushi. This style of sushi, which emerged in the 1820s and is the foundation of modern sushi, is confined to fish sourced from Tokyo Bay. Salmon, while widely beloved, is not native to Japan and thus is not part of the traditional Edomae sushi tradition. Introduced to Japan by Norwegian fish merchants in the late 19th or early 20th century, salmon has remained on the fringes of sushi culture due to its relatively cheaper nature, often relegated to conveyor belt sushi or lesser-traditional sushi bars.

The Salmon Revolution

The transformation of salmon from an obscure ingredient to a popular sushi choice was driven by Bjorn Eirik Olsen, a key figure in the Norwegian salmon industry. In the 1980s, when there was an overabundance of salmon, Olsen saw an opportunity to change Japanese culinary habits. His mission was to popularize salmon sushi in Japan, a country known for raw fish consumption.

Olsen recognized that Japanese sushi chefs and the broader culinary community were wary of raw salmon, primarily due to the historical risks associated with parasites. To overcome this, Olsen, with the help of Japanese frozen food company Nichirei, negotiated a deal to supply 5000 tons of salmon at a reduced price. This breakthrough not only addressed the problem of salmon overstocking in Norway but also laid the groundwork for the eventual acceptance and popularity of raw salmon sushi in Japan.

Conclusion

From salt-preserved fish to a beloved ingredient in sushi, the journey of salmon in Japanese cuisine is a testament to the evolution of culinary traditions. The successful integration of salmon sushi into modern sushi culture underscores the ever-changing nature of food trends and how innovation can bridge cultural and culinary gaps.
