Wagyu in Japan: Kobe, Matsusaka, Omi — The Regional Beef Guide

Wagyu (wa = Japanese, gyu = cattle) refers to four breeds of Japanese cattle with a specific genetic predisposition to intramuscular fat — the fat marbles through the muscle fiber rather than concentrating in exterior fat deposits. The result is beef with a fat content of 25–40% (vs. 5–10% for premium Western beef), a melting point below body temperature, and a richness that is categorically different from any other beef in the world.

The word “wagyu” outside Japan often refers to crossbred cattle or marketing. In Japan, the real product — pure Japanese black (kuroge washu) cattle raised to specific standards — has regional certification systems that trace individual animals through their lifetime.

The Three Great Regional Brands

Kobe Beef (Hyogo Prefecture)

The most famous Japanese beef brand internationally — and the most counterfeited. True Kobe beef must come from tajima-cattle (a specific bloodline of Japanese Black cattle) born and raised in Hyogo Prefecture, slaughtered at designated facilities in the Kobe area, with a BMS (Beef Marbling Score) of 6 or above on the Japanese A4–A5 scale, and registered with the Kobe Beef Marketing and Distribution Promotion Association.

The number of authentic Kobe beef cattle certified per year is approximately 4,000–5,000. Almost all is consumed within Japan; the export volume is minuscule. “Kobe beef” on a menu outside Japan almost certainly isn’t.

Where to eat it in Kobe: The Kitano-cho and Harborland areas have the highest concentration of certified Kobe beef restaurants. The most accessible format for travelers is teppan (iron griddle) — the chef cooks the beef in front of you, slice by slice. A small portion (100g, enough to understand the product) at a teppan restaurant runs ¥5,000–8,000. A full teppan course with multiple cuts runs ¥15,000–25,000.

Matsusaka Beef (Mie Prefecture)

Often considered the superior beef to Kobe by Japanese connoisseurs — a rarer, more expensive product with a BMS that often reaches 12 (the maximum) compared to Kobe’s minimum of 6. Matsusaka beef comes only from virgin female Japanese Black cattle raised in the Matsusaka area of Mie Prefecture, fed a specific diet over 30+ months. The total annual production is approximately 2,000–2,500 cattle.

The flavor profile: more intense than Kobe, with a slightly sweeter fat character. The fat melts at a lower temperature; the texture at A5 grade is almost liquid.

Where to eat it: In Matsusaka city (accessible from Nagoya or Osaka by JR), the sukiyaki preparation is traditional — thin slices of beef cooked in sweet soy sauce with vegetables at the table. Lunch sukiyaki courses start at ¥5,000–8,000; dinner courses at ¥15,000–30,000.

Omi Beef (Shiga Prefecture)

Japan’s oldest beef brand, with documentation going back 400 years — the Omi merchants who carried Omi beef to Edo were the original commercial beef culture in Japan. Raised in Shiga Prefecture (adjacent to Kyoto, surrounding Lake Biwa), Omi beef has a slightly firmer texture than Kobe and Matsusaka with a very clean fat character.

The relative obscurity of Omi beef internationally means the price is lower than Kobe despite comparable quality. Accessible in Shiga Prefecture at more modest prices than the famous two brands.

How to Eat Wagyu

Yakiniku (Grilled at the Table)

The most interactive format: raw marbled beef slices are brought to your table, and you grill them over a gas or charcoal grill embedded in the table. The beef is eaten with dipping sauces (soy-based tare, salt with lemon, sesame oil), rice, and namul (seasoned vegetables — the Korean heritage of yakiniku is visible in the accompaniments).

For wagyu at yakiniku: the tanuki (thin-sliced belly) and karubi (short rib) cuts show the marbling most dramatically. The A5 grade should be placed on the grill for only 15–20 seconds per side — enough to warm the fat through, not to cook the interior to more than rare.

Yakiniku price range: ¥3,000–15,000 per person depending on grade and restaurant.

Sukiyaki

Thin slices of wagyu cooked tableside in a sweet soy and mirin broth (warishita), with tofu, noodles, and vegetables, dipped in raw beaten egg before eating. The egg coats the meat and slightly cools it; the combination with the sweet cooking liquid is the traditional high-quality wagyu preparation. Warming in autumn and winter; the cooking and eating pace is slow, social, and appropriate for the most expensive grades.

Shabu-shabu

The lighter alternative to sukiyaki — paper-thin wagyu slices briefly swirled in delicate kombu broth (shabu-shabu is onomatopoeia for the swishing sound), cooked for 5–10 seconds, dipped in sesame sauce or ponzu. The fat melts from the surface into the broth; the remaining meat is lean and clean.

Teppan (Iron Griddle)

The Kobe beef format — thick cuts seared on a flat iron griddle by a chef at a counter. The Kobe beef steak that appears in most tourist-facing Kobe restaurants is this format. The visible char on the exterior and the pink interior contrast; the fat pooling around the steak as it cooks is part of the presentation.

Grades and What They Mean

Japanese beef grading uses two axes:

Yield grade (A, B, or C): Proportion of usable meat from the carcass. Grade A is the highest yield.
Quality grade (1–5): Based on marbling score (BMS 1–12), color, firmness, and fat quality.

A5 (A yield, 5 quality, BMS 8–12): The highest designation — extremely marbled, essentially buttery. Should be eaten in small portions (100–150g per person is genuinely sufficient for A5 grade); eating a large A5 steak produces fat fatigue.

A4 (BMS 5–7): Excellent quality, less extreme marbling than A5. Actually preferred by many Japanese connoisseurs who find A5 too rich for large servings.

A3: Still premium quality by any international standard; the accessible entry point to certified wagyu at restaurants.

Budget Options

Gyudon: The gyudon chain restaurants (Yoshinoya, Sukiya, Matsuya) serve sliced wagyu-grade beef over rice for ¥400–600 — not A5 certified, but from the same breed of cattle at lower grades and less regulated production. The best available fast food anywhere in the world at the price.

Supermarket wagyu: Japanese supermarkets sell A3–A4 wagyu at retail prices (¥500–2,000 per 100g for lower grades). Buying supermarket wagyu and cooking it yourself — or having a hotel kitchen access — gives the product at wholesale-adjacent pricing.

Lunch vs dinner: A5 wagyu restaurants that offer ¥3,000–5,000 lunch sets are serving the same beef as their ¥20,000 dinners. The portion is smaller; the value is dramatically better.

Wagyu is the food most likely to recalibrate your reference point for beef permanently. Eating A5-grade matsusaka sukiyaki in Matsusaka, or a teppan course in Kobe, produces a standard of comparison that makes most subsequent beef — in Japan or elsewhere — taste like a different food. The investment is worth it once; the ¥5,000 lunch is a more practical entry point than the ¥25,000 dinner.
