Wagyu vs. Imported Harami: Meat Quality, Price Hikes, and Kuro5’s Sourcing Secret

1. Harami: The Cut that Captivates Yakiniku Fans and Its Hidden History

Hello everyone. This is Kuro5’s Sondo.

When you visit a yakiniku restaurant, you might order short ribs (karubi) or loin (rosu), but there is one particular cut that has a cult-like following: “Harami” (skirt steak). Offering a rich, beefy flavor and a satisfyingly tender chew without being overly greasy, harami has secured a permanent spot at the top of modern Japanese yakiniku popularity. From older generations who prefer a lighter bite to younger diners seeking rich, savory satisfaction, harami is a versatile favorite that brings smiles to every table.

However, did you know that harami is not technically classified as “red meat”? According to the Japanese Ministry of Agriculture, Forestry and Fisheries, harami belongs to the category of “organ meats” (horumon). Harami refers specifically to the thin section of the diaphragm muscle, which, along with the rib-side diaphragm muscle (sagari), forms a breathing organ. Because it is a diaphragm muscle rather than skeletal muscle, it is relatively low in calories compared to standard cuts like short ribs, yet it is packed with the intense, deep umami characteristic of organ meats. The fiber structure is rich and yields a wonderful texture, releasing a burst of hot, savory juice with every bite—a unique charm that sets it apart from standard red meat.

Today, we will focus on this popular cut and explain the defining differences between Wagyu Harami and Imported Harami. We will also explore the recent dramatic price increases in the global beef market, the sourcing secrets that allow Kuro5 to secure fresh “raw Wagyu harami” every single day, and the professional grilling techniques we use to elevate its flavor. By the end of this article, your next bite of harami will taste deeper and more satisfying than ever before.

2. Sweet Fat and Rich Umami: Defining Differences in Meat Quality Between Wagyu and Imported Harami

What are the differences between Wagyu Harami and Imported Harami? The primary contrasts lie in the distribution of fat (marbling), the depth of the cooking aroma, and the processing state in which the meat arrives in Japan.

First, Japanese Black Wagyu Harami (Wagyu Harami) is exceptionally thick and features a beautiful network of fine marbling (sashi) woven throughout the muscle fibers. Because of the genetic characteristics of Wagyu cattle and the meticulous care with which they are raised, even organ cuts like the diaphragm develop high-quality, sweet fat. This fat is highly rich in oleic acid, giving it a low melting point that dissolves at body temperature the moment it enters your mouth. The sweetness of the fat and the robust umami of the lean meat merge seamlessly, leaving a luxurious, lingering buttery aroma (Wagyu Aroma) after swallowing. This is the scientific reason Wagyu harami is celebrated as an elite cut of meat, offering an incredibly tender texture where the fibers gently fall apart under your teeth.

On the other hand, imported harami from countries like the United States and Australia features a different texture and cutting philosophy. Most imported harami is shipped to Japan after being heavily trimmed at the local packing facility. The thick outer fat, membranes, and tough tendons are removed beforehand, arriving as a clean, lean block of beef that is easy for kitchens to handle. In terms of flavor, it offers a strong, iron-rich beefiness and a firm chew, delivering a direct sense of satisfaction that appeals to lean beef lovers. However, it lacks the deep complexity, melting tenderness, and sweet aroma of Wagyu. Imported harami is best appreciated as a clean, pre-trimmed lean cut rather than a marbled luxury.

3. The “Meat Shock” Shift: Why Wagyu’s Real Value Shines Amid Imported Beef Price Hikes

In recent years, the global beef industry has been hit by rapid price hikes known as the “Meat Shock,” affecting both professional yakiniku restaurants and family dinner tables. A combination of factors—including global population growth, rising demand for beef in emerging economies, severe labor shortages at packing plants, surging grain feed costs, high oil prices affecting shipping, and dramatic currency fluctuations—has pushed the wholesale price of imported beef to unprecedented heights.

To put this into numbers, the wholesale price of US frozen short plates (a staple for many Japanese restaurants) rose by a staggering 360 yen per kilogram in just one year. Specifically, the price jumped from 687 yen per kilogram in January 2021 to 1,047 yen per kilogram in January 2022. This price surge has also impacted imported harami, with its wholesale cost rising to several times what it was a few years ago. Imported beef, which was once prized primarily for its low cost and high volume, is no longer a cheap ingredient.

This price hike has shifted the way customers choose their dishes at yakiniku restaurants. In the past, there was a major price gap between cheap imported harami and premium Wagyu harami. Today, however, because the cost of imported beef has risen so sharply, that price gap has narrowed significantly.

As a result, spending a little extra to choose Wagyu harami offers incredible value for money today. More and more guests are realizing that since the price difference has shrunk, it is far more satisfying to enjoy genuine, domestic Wagyu harami. In this shifting economy, the true cost-performance of Wagyu harami has never been clearer.

4. Only 2kg per Cow: Sourcing “Raw Wagyu Harami” Through Deep Partnerships with Wholesalers

While the value of Wagyu harami rises, the difficulty of sourcing it has reached an all-time high. A single head of cattle (weighing around 600 to 700 kilograms) yields only about 4 to 5 kilograms of harami. Furthermore, once the kitchen trims away the tough tendons, excess fat, and outer membranes to prepare clean slices for the grill, the edible portion shrinks to a mere 2 kilograms per cow.

Because Wagyu harami is so scarce and in high demand nationwide, meat wholesalers face a unique challenge: harami alone does not generate enough profit for their business. Wholesalers cannot survive by selling only rare harami. Consequently, they distribute Wagyu harami preferentially to restaurants that buy whole carcasses (edaniku) or large primals regularly, and to partners with whom they have built long-term relationships of trust over many years.

This means that even a large restaurant chain with massive purchasing power cannot simply buy raw Wagyu harami on demand. Sourcing it consistently requires a history of mutual respect and cooperation with the meat market.

The reason Kuro5 can serve fresh, never-frozen “raw Wagyu harami” daily is the deep partnership we have maintained with our wholesalers since our founding. We show our commitment by buying consistently through all market conditions, paying fair prices, and respecting the wholesalers’ work. Thanks to this mutual trust, we are given priority access to the finest raw Wagyu harami, ensuring our guests always enjoy the best quality available.

5. Our Commitment to Never-Frozen “Raw” Beef: The Science of Cell Walls and Drip Prevention

At Kuro5, our absolute rule for Wagyu harami is that it must never be frozen. While much of the imported harami and even some Wagyu harami on the market is frozen for transport and storage, we refuse to compromise on this point. In the culinary science of beef, freezing makes a massive difference in quality.

When meat is frozen, the water content inside the tissues freezes into sharp ice crystals. As these crystals grow, they puncture and destroy the delicate cellular walls of the meat. When the beef is thawed, the broken cell walls allow the precious moisture to escape as “drip.”

This drip is not just water; it contains the meat’s amino acids, nutrients, and rich umami components. Once the drip escapes, the meat becomes dry, tough, and prone to developing the gamey, iron-like smell typical of frozen-thawed organ meats. No matter how carefully you grill it, frozen-thawed meat can never regain its original juiciness.

By serving only never-frozen “raw Wagyu harami,” Kuro5 keeps the cellular structure of the beef completely intact. When placed on the grill, the cells retain all the moisture, fat, and umami inside. The moment you take a bite, the sweet Wagyu fat and savory juices burst forth in a harmony of flavor that is only possible with fresh, raw beef.

6. A Two-Centimeter Challenge: Why Raw Wagyu Harami Needs No Scoring for Ultimate Tenderness

Sourcing high-quality raw Wagyu harami is only the first step. The next step relies on the skills of our kitchen staff. Because harami has a distinct, fibrous structure, the way it is cut determines its final tenderness and mouthfeel.

Kuro5 serves our raw Wagyu harami in thick slices of about 2 centimeters. We choose this thickness because we want our guests to experience the full, juicy texture that harami has to offer. However, when standard yakiniku restaurants offer such thick-cut harami, they usually apply a technique called “scoring” (hidden cuts – kakushi-bocho) to make the fibers easier to bite through. Without it, thick-cut meat can easily become tough and difficult to chew.

At Kuro5, however, we never apply scoring to our Wagyu harami. Because our fresh Wagyu harami has never been frozen, its cellular structure remains completely intact, preserving its natural, melt-in-your-mouth tenderness. It is so tender that you can bite through the thick 2-centimeter cut effortlessly without any scoring.

Furthermore, there is another critical reason we avoid scoring: to ensure a perfectly crispy, caramelized surface sear. If the surface of the meat has fine cuts, the precious meat juices will leak out excessively during grilling, which prevents the exterior from searing properly. By keeping the surface completely whole, Binchotan charcoal’s powerful far-infrared heat can sear the exterior evenly to a crispy, fragrant finish while locking all the sweet, rich Wagyu juices securely inside the meat. Avoiding unnecessary prep is Kuro5’s subtraction philosophy, showcasing the raw ingredients in their purest form.

7. Charcoal and Infrared Magic: Kuro5’s Grilling Art to Seal in Juices

Once prepped, the harami is ready for the final step: the charcoal grill. Harami loses moisture quickly if left too long on the heat, causing the fibers to tighten and become rubbery. Grilling requires a careful touch to cook the meat through without losing its juices.

To ensure a perfect cook, Kuro5’s trained staff grill the meat for you at your table as part of our signature tableside service.

We use premium Binchotan charcoal, which generates intense, dry heat and powerful far-infrared waves. Unlike gas fires, which release water vapor as they burn, Binchotan charcoal cooks the meat quickly from the inside out while searing the surface to a crisp, caramelized finish.

The secret to grilling harami is to avoid high, direct flames. We place the meat in the stable, medium-heat zone of the grate and flip it repeatedly. By flipping the meat frequently, we ensure that the surface does not burn and that the melting fat circulates back into the center, basting the beef from within. This slower, patient grilling method creates a beautiful contrast: a crispy, fragrant exterior and a tender, juicy interior that locks in all the sweet Wagyu juice. It is the ultimate way to bring out 120% of the raw Wagyu’s natural flavor.
