Why does Japan have such a refined sashimi culture?

The answer lies in one surprising element: the unmatched sharpness of the Japanese knife.
Sashimi is not simply raw fish—it is a culinary technique that demands extreme precision. To achieve slices as thin as paper without damaging the fish’s structure, chefs rely on knives so sharp they border on surgical instruments.
The evolution of the yanagiba in the Edo period marked a turning point. With its long, single-bevel edge, the yanagiba allows chefs to slice in a single, smooth motion, preserving both beauty and texture. From delicate sardines to lustrous horse mackerel, Japanese knives reveal the true form of each ingredient without crushing or tearing.
In this way, Japanese craftsmen did more than improve cooking—they perfected the art of cutting itself. Without such exceptional blades, the elegance and subtlety of sashimi would not exist.
In the hands of a skilled chef, a Japanese knife doesn’t just cut—it reveals the soul of sashimi.
