Wagyu Beef: Japan’s Most Expensive Meat — and Why It’s Worth Every Yen
By Yoshi | Japan Unveiled
I want to begin with a price that will seem, to almost everyone reading this, unreasonable.
At the Matsusaka Beef auction that takes place annually in Matsusaka City, Mie Prefecture — approximately an hour’s drive south of Nagoya, in a part of Japan that I know well because I have driven through it many times — the top-grade wagyu bull has sold for prices exceeding 50 million yen.
50 million yen. For one bull. Whose meat will eventually be divided into portions and sold at prices that, for the finest cuts from the finest animals, can exceed 100,000 yen per 100 grams.
These numbers are real. They describe a product that exists, that is eaten by people who can afford it, and that — by the accounts of the people who have eaten it at the highest quality levels — justifies, in the specific eating experience, something approaching the price.
I have not eaten 100,000 yen per 100 gram wagyu. I have eaten wagyu of various grades across my life, living as I do in the region where some of Japan’s finest wagyu is produced. I have eaten Matsusaka beef at levels of quality that were, by any reasonable measure, extraordinary. And I want to tell you honestly what the experience is and what the premium buys.
What Wagyu Is
Wagyu (和牛) — the characters mean simply “Japanese cattle” (wa = Japan, gyū = cattle) — refers to four specific breeds of Japanese cattle that have been developed, through selective breeding over generations, to produce beef with specific characteristics of intramuscular fat deposition that distinguish it from virtually all other beef in the world.
The four breeds: Japanese Black (Kuroge Washu, the dominant variety, producing the beef most associated with wagyu internationally), Japanese Brown (Akaushi), Japanese Shorthorn (Nihon Tankaku), and Japanese Polled (Mukaku Washu). Of these, Japanese Black accounts for approximately 90% of wagyu production.
The defining characteristic of wagyu is its marbling — the intramuscular fat that appears within the muscle tissue rather than only as external fat deposits. In standard beef cattle, fat is deposited primarily around the muscles and organs; the muscles themselves are relatively lean. In wagyu, through a combination of genetics and specific raising conditions, fat is deposited within the muscle fibres themselves, producing the characteristic white marbling pattern visible in cross-section.
This marbling is what distinguishes the eating experience of wagyu from standard beef, and understanding the specific physiological and chemical reasons for the difference explains why the experience is what it is.
The Science of Marbling: Why Fat Inside the Muscle Matters
The specific eating quality that wagyu’s marbling produces is the result of two distinct mechanisms operating simultaneously.
The melt point. The intramuscular fat in wagyu has a lower melting point than the fat in standard beef — approximately 25-30°C, compared to approximately 40-50°C for most beef fat. This low melt point means that wagyu fat begins to render at temperatures that are significantly below the cooking temperature — it begins to melt when it contacts the warmth of the mouth, rather than requiring the high temperatures of the cooking process to become liquid.
The specific effect: when a piece of well-marbled wagyu is placed in the mouth, the fat that has been rendered during cooking (providing juiciness and flavour) is supplemented by the fat that continues to render from the residual heat of the meat and the warmth of the mouth itself. The fat dissolves into a smoothness that standard beef fat, with its higher melt point, does not achieve.
The fatty acid composition. Wagyu fat has a higher proportion of monounsaturated fatty acids (particularly oleic acid — the same fatty acid that characterises olive oil) relative to saturated fat, compared to standard beef fat. Oleic acid contributes to the specific flavour quality of wagyu — its particular richness without heaviness, the specific way it feels in the mouth — and is associated with the specific sweet, buttery flavour note that characterises the finest wagyu.
The combination of low melt point and high oleic acid content produces the specific eating experience that distinguishes wagyu at its finest: the immediate yielding tenderness as the meat makes contact with the tooth, the fat that dissolves into the warm moisture of the mouth rather than requiring chewing, the specific sweet, rich flavour that builds and sustains through the eating rather than dissipating immediately.
The Three Great Wagyu: Matsusaka, Kobe, Yonezawa
Japanese wagyu has several regional varieties that have achieved specific recognition as the finest expressions of the form — the specific combination of breed, feeding programme, and regional conditions that produces the most celebrated beef in Japan.
Matsusaka Beef (Matsusaka-gyu, Mie Prefecture) — I want to be direct about my regional bias here before I write anything further: Matsusaka is in Mie Prefecture, which is adjacent to my home region. I have eaten Matsusaka beef many times. I think it is extraordinary. I am not claiming to be objective.
Matsusaka beef uses only virgin female Japanese Black cattle — the specific decision to use only females, and only those who have never calved, is based on the specific quality of female cattle fat, which is considered smoother and more finely distributed than the fat of male or parous female animals. The cattle are raised for a specific minimum period under a specific feeding programme that emphasises feed quality and minimal stress, and the raising conditions are strictly regulated by the Matsusaka Beef Society.
The result is the most highly marbled and most highly priced of Japan’s wagyu varieties — the beef that achieves the most extreme examples of intramuscular fat deposition and that produces, at its finest levels, the specific buttery, dissolving quality that wagyu at its most extreme offers.
Kobe Beef (Kobe-gyu, Hyogo Prefecture) — the most internationally famous wagyu variety and the name most often misused internationally (genuine Kobe beef is produced under extremely strict standards from a specific herd of Japanese Black cattle raised in the Tajima region of Hyogo Prefecture; much of what is called “Kobe beef” outside Japan does not meet these standards and is not genuine Kobe beef).
Genuine Kobe beef is produced from Tajima cattle — a specific genetic line of Japanese Black with particularly fine marbling characteristics — raised in the Hyogo region and slaughtered at specific facilities. The yield from this system is deliberately limited — approximately 5,000 animals per year qualify for genuine Kobe beef designation — which is one reason for both the premium pricing and the frequency of misuse of the name internationally.
Yonezawa Beef (Yonezawa-gyu, Yamagata Prefecture) — alongside Matsusaka and Kobe, considered one of Japan’s three great wagyu. Yonezawa beef cattle are raised in the Yonezawa basin in Yamagata Prefecture, in conditions that the region’s specific climate and agricultural character create. The Yonezawa style produces beef with somewhat different characteristic flavour notes from the other two — the specific environment of the Yonezawa basin, including the feed grown there, contributes a specific quality to the fat flavour.
Ōmi Beef (Ōmi-gyu, Shiga Prefecture) — often cited as Japan’s fourth great wagyu, with the longest wagyu tradition of any variety — the cattle of Ōmi (the historical name of Shiga Prefecture) were being raised for beef consumption from the seventeenth century, earlier than the other regional varieties.
The Grading System: What the Numbers Mean
Japanese wagyu is graded according to a specific system administered by the Japan Meat Grading Association (JMGA) that evaluates two dimensions: yield grade and quality grade.
Yield grade (A, B, or C) — the proportion of the animal’s weight that produces usable meat. A-grade animals have the highest yield; C-grade the lowest. Most premium wagyu is A-grade.
Quality grade (1-5) — a composite assessment of four quality factors, each rated 1-5:
- Marbling (Beef Marbling Score, BMS 1-12, with 12 being the most extreme marbling)
- Meat colour and brightness
- Firmness and texture of the meat
- Fat colour, lustre, and quality
The quality grade (1-5) is the lower of the four factor scores, meaning that a single below-average factor will lower the overall grade regardless of other factors’ performance. Grade 5 in all four factors, with a BMS of 10-12, represents the highest quality level.
The grade you most commonly see in premium wagyu contexts: A5 — the highest combination of yield grade (A) and quality grade (5). A5 wagyu, combined with a high BMS, is the designation that commands premium prices and that represents the specific eating experience of wagyu at its most extreme.
How to Eat Wagyu Correctly
The specific characteristics of high-quality wagyu require specific eating approaches to fully realise them.
Yakiniku (Japanese BBQ style) — thin slices of wagyu, briefly cooked on a charcoal or gas grill at high heat, eaten immediately. The thin slice allows rapid cooking that sears the exterior while the interior warms just enough to begin the fat rendering process. Each piece is eaten in one or two bites, at maximum temperature. This is the most common format for eating premium wagyu in Japan and arguably the format that best expresses its specific qualities.
Shabu-shabu — I have written about this in the shabu-shabu article. The very thin wagyu slice swished through hot broth produces, through the combination of brief heat and warm broth, the specific melting quality that wagyu is famous for. The ponzu dipping sauce’s acidity provides the necessary counterpoint to the fat richness.
Sukiyaki — the sweet-savoury warishita sauce caramelises on the wagyu’s surface during cooking, and the raw egg dip cools and enriches each piece. The sweetness of the warishita is a classical pairing with wagyu’s specific fat character.
The steak approach — less common in Japan, more common internationally: the thick-cut wagyu steak, cooked to medium-rare, as a standalone presentation. Japanese purists sometimes note that the extreme fat content of A5 wagyu means that a thick-cut steak can be overwhelming — the amount of rendered fat that a thick A5 steak produces can exceed what the appetite can comfortably sustain. Smaller portions, or thinner cuts, are often recommended over the restaurant-steak format for the highest-grade wagyu.
Where to Eat Wagyu in Japan
Matsusaka City, Mie — for Matsusaka beef, visiting the source is the ideal. The city has numerous restaurants specialising in the local product, ranging from the extremely expensive (Wagyumafia-adjacent high-end establishments) to the more accessible (set menus at mid-range yakiniku restaurants that use genuine Matsusaka beef). Arriving by local train from Nagoya or Matsusaka and spending lunch in the city is a manageable day trip from central Japan.
The Ginza and Roppongi, Tokyo — both areas have concentrations of high-end wagyu restaurants, including several that specialise in Kobe, Matsusaka, and various premium regional varieties. These are the most expensive options but also the most controlled — restaurants in these areas have the volume and the sourcing relationships to maintain consistent high quality.
Department store basement food halls (depachika) — high-quality wagyu in portioned raw form is available at the meat counters of major department store basements. Purchasing wagyu from a depachika and cooking it at home — in a tabletop shabu-shabu or yakiniku setup — is a cost-effective way to experience genuine high-grade wagyu.
