This breed accounts for about 98% of all Wagyu cattle in Japan and is known for its exceptional marbling. It is the primary breed used for famous Japanese beef brands like Kobe and Matsusaka, offering rich flavor and a melt-in-the-mouth texture.

Japanese Black

黒毛和種

This rare Wagyu breed, naturally hornless, was developed by crossbreeding with Aberdeen Angus. Currently, it is only raised in Yamaguchi Prefecture and produces leaner meat while maintaining Wagyu’s signature tenderness.

Japanese Polled

無角和種

Also known as "Akaushi," this breed has a reddish-brown coat and is primarily raised in Kumamoto and Kochi. Its meat is leaner yet tender, with a well-balanced flavor and moderate marbling.

Japanese Brown

褐毛和種

This breed originates from the Tohoku region and is well adapted to harsh climates. Around 7,000 head are raised nationwide, mainly in northeastern Tohoku and Hokkaido, with about 40% of them concentrated in Iwate Prefecture.

Wagyu Brands

Japan produces over 320 wagyu brands raised in regions all over the country. Similar to how wine is categorized by its region and method of cultivation, each wagyu brand meets unique standards according to the production area, bloodline, breed, grade, the method of rearing and period of time raised.

A heartfelt thank you for the growing love from around the world!

Export Volume of Wagyu from Japan

Dawn of Global Expansion

Throughout the 1900s, a small amount of wagyu was exported from Japan. After being certified as a "BSE-free country" with the lowest risk by an international organization in 2013, exports gradually expanded, supported by government promotional efforts.

一番食べてみたい

"Matsusaka Beef" in particular is a highly coveted brand, followed by "Kobe Beef" and "Yonezawa Beef."

Speaking of Kobe beef, let me introduce you to my friend Yuki. He is from Kobe and co-authored this story!

"Hi, I’m Yuki."

"I was born in Hyogo Prefecture🇯🇵,

where some of the world’s best beef is raised."

"To me, these cows were just part of the scenery.

I had no idea they were living legends."

"But as a kid, I didn’t think much of it."

"Dad, why do these cows look so… relaxed?

Because they’re treated like royalty. Happy cows make the best beef."

"What… it’s so tender. It just melts!"

"This isn’t just any beef, Yuki. This is Kobe Beef, Hyogo’s pride!"

"Only Tajima Beef, raised in Hyogo under strict rules, can be called Kobe Beef."

"That was the moment I realized, this wasn’t just food. It was art!"

"So let me explain the magic of Kobe Beef, the Wagyu brand from my home!"

What makes Kobe Beef so special?

Tajima Beef and Kobe Beef have specific definitions that are considered the strictest in Japan. Only beef that meets these criteria can be recognized as Kobe Beef and distributed globally.

Meat Grading System

Meat grade is one of the criteria used to define Tajima and Kobe Beef.

Tajima Beef

  • Graded A2–A5 or B2–B5 in the meat grading system
  • Bred and fattened in Hyogo Prefecture
  • Steer or cow, aged between 28 and 60 months
  • Processed at slaughterhouses in Hyogo Prefecture

Kobe Beef

Kobe Beef should be selected from Tajima Beef that meets following conditions

  • Graded A4, A5, B4, or B5 in the meat grading system
  • 270kg—499.9kg for cow or 300kg—499.9kg for steer

Not All Tajima Earns the Kobe Name

With these strict criteria, how many Tajima Gyu are selected as Kobe Gyu?

Source:

2008

In 2008 for example, only half of Tajima Gyu were selected as Kobe Gyu.

2013

In 2013, this percentage jumped to 65%.

2018

To over 80% in 2018.

2023

Why the increase? The number of Kobe Gyu has been increasing in recent years due to the expansion of breeding cows, increased production of fattening cattle through embryo transfer, improvements in feed, and enhanced information dissemination.

From Hyogo to the World

With an improvements in certification rate, constructing meat processing facilities for export, and enhancing its brand power, Kobe beef has begun to be exported overseas.

Let's zoom in Hyogo

Hyogo Prefecture

Hyogo Prefecture is located in western Japan and is home to Kobe. It features a diverse landscape, including mountains, coastline, and rich cultural heritage.

Designated Farms

Tajima and Kobe Gyu are produced at designated farms in Hyogo. They belong to each region's Japan Agricultural Cooperatives.

Number of Designated Farms

JA Tajima in the Tajima region has the largest number, followed by JA Hyogo Rokko in Kobe and JA Awaji Hinode in Awaji Island.

From Hyogo to the World

In 2024, a total of 51.2 tons of Kobe beef was exported to 19 countries and regions.

But I'm not the only one from Hyogo going abroad, Yuki just started his Ph.D. in the U.S.

Yuki arrives in the U.S. to start his P

h.D., feeling both excited and anxious.

But Wagyu is not ea

sy to find in the U.S.

And it's not commonly serv

ed at American restaurants.

In fact, there are major difference

and many other countri

s in how cows are raised in the U.S

es, compared to Japan.

Late at night, Yuki scrolls through hi

s phone, staring at pictures of Wagyu.

Inspired, Yuki finds some Wag

and invites h

yu at a specialty butcher

is lab members.

Yuki hopes to bring his l

so they too can fully exp

ab mates to Japan one day,

erience the story of Wagyu.

Major Beef Producing Regions Comparison

Compared to other types of beef, wagyu is usually much more expensive, especially in countries like the U.S. and Australia.

One reason for this is that Japan’s highest Wagyu grade sets a far higher standard than the top beef grades in the U.S. and Australia. Even lower-graded Wagyu is equal to or better than the top grades in these countries.

The Unique Flavors of Each Cut

The beauty of beef lies in its diverse flavors, from marbling to texture, unique to each cut. You can hover over the cow illustration to explore the characteristics of each cut.

It's art, culture, and history on a plate."
