Origin & Heritage
History
Razor clams have been harvested for centuries in European coastal regions, particularly in Spain and Portugal where they remain deeply embedded in local gastronomic traditions. In Asia, Japanese and Korean cuisines have long incorporated razor clams, particularly in sushi and raw preparations. North American populations were traditionally harvested by indigenous coastal communities and later became commercially significant in Washington State and Oregon.

In Japan, razor clams (aoyagi or mirugai) are esteemed in sushi culture and represent premium sushi ingredients. Along the Atlantic coast, they symbolize regional coastal heritage and fishing traditions.
