Japanese Chicken Sashimi: Reality of Torisashi & Toriwasa

While consuming raw poultry is considered a culinary taboo in Western culture, it is actually a delicacy in traditional Japanese cuisine. Known as torisashi (chicken sashimi) or toriwasa (chicken lightly seared and paired with wasabi), this preparation involves serving thinly sliced, essentially raw chicken breast, tenderloin, or liver. Far from a casual home-cooked meal, the tradition relies on specialized agricultural supply chains, meticulous kitchen preparation, and unique regional culinary histories.

The Anatomy and Slicing of Torisashi

For torisashi or toriwasa in Japan, chefs use the part of the chicken that the American poultry industry refers to as the tenderloin. This is the delicate strip of flesh located on both sides of the chicken breast, where the pectoralis minor muscles attach to the breastbone. Because these specific strips are shaped remarkably like bamboo-grass leaves, known as sasa in Japanese, the cut is traditionally called sasimi (sashimi) or “bamboo-grass meat.”

While it is occasionally prepared using regular breast meat, thighs, or even liver, the tenderloin remains the standard for premium raw presentations. This specific portion of the breast muscle is naturally the most tender when raw, allowing it to be sliced into the exceptionally thin, delicate pieces required for authentic sashimi presentation.

The Blanching Technique: Is Chicken Sashimi Completely Raw?

It turns out that chicken sashimi is not completely raw. Traditional preparation dictates that the poultry is quickly dipped into boiling water before slicing. According to culinary authority Shizuo Tsuji in Japanese Cooking: A Simple Art, this immersion is done for roughly 30 seconds. Other historical and regional variations call for even less time, ometimes as little as ten seconds, or just two rapid dips.

The purpose of this brief flash-blanching is to “refresh the meat” and completely neutralize any surface off-odors. The heat turns the outermost layer white while leaving the interior muscle tissue essentially raw. After blanching and cooling, the chicken is cut into thin, sashimi-style slices. It can then be lightly coated in wasabi and soy sauce, or served with these components on the side, frequently accompanied by toasted nori and sliced cucumber.

Agricultural Standards and the Reality of Raw Poultry

When Western diners discover that raw chicken is served in Japan, it often triggers a common “halo” assumption about the respective food supplies. Because Americans are strictly conditioned to never consume raw poultry, there is a frequent misconception that the existence of torisashi implies American poultry is inherently inferior, or that Japanese agriculture has somehow produced risk-free, “magic” chickens.

The reality is far more standardized. High-end sashimi establishments in Japan do take their poultry sourcing exceptionally seriously, dealing with small, specialized local farms that raise birds to exacting standards and deliver them ultra-fresh daily. However, this meticulous sourcing does not alter the fundamental biological nature of the chicken.

In fact, Japan’s Ministry of Health, Labour and Welfare routinely issues public warnings against consuming raw poultry, explicitly asking restaurants to adjust their cooking practices to ensure chicken is heated to a safe internal temperature. The inherent microbial risks of handling and consuming raw chicken remain exactly the same regardless of geography. The tradition persists not because the livestock is biologically different, but because of a cultural willingness to accept those baseline risks in a highly regulated commercial kitchen environment.
