Bloodlines - Japanese Black
Although the breed was closed to outside bloodlines in 1910, regional isolation has produced a number of different lines with varying conformations:
Prefecture |
Original Bulls |
Bloodlines |
Hyogo (Tajima) |
TAJIRI |
Naka-Doi line, Kikumi line, Okudoi line |
Not all of these bloodlines are represented in Wagyu outside of Japan because the Japanese government banned any additional exports of Wagyu genetics around 1994. This was in connection with the Japanese government realizing the value of Wagyu and declaring them a national treasure of Japan.
Below are the main bloodlines which are utilized by breeders outside of Japan:
Hyogo (Tajima) Prefecture cattle are the descendents of Tajiri, a sire born in Mikata District. These cattle have outstanding genetic excellence with finely marbled beef in combination with a smaller frame and lower growth rates. They are renowned for good temperament. Famous are the names Kobe Beef and Matsuzaka Beef, from herds produced in the Hyogo Prefecture using Tajiri bloodlines. The Naka-Doi, Kikumi, and Okudoi lines are used today.

Shimane Prefecture cattle are well-balanced and produce calves with good growth rates and meat quality. They also have a quiet temperament and exhibit a strong maternal ability in dams, which consequently also have very high fertility rates.
Dai 7 Itozakura pictured to the left is probably the most famous of the
Itozakura line and is shared with the Okayama Prefecture. Mr. Shogo Takeda used this bloodline to develop much of his cow herd as well as many of his foundation sires.
Tottori Prefecture cattle are from the descendants of the sire Eiko. The typical characteristics of these cattle include good growth, larger frame type, good top line, and overall balance. They are known for their fine, loose skin. The most prevalent is the Kedaka line which started in 1959.
