Wagyu 

Cattle were brought to Japan from China at the same time as the cultivation of rice, in about the second century AD, in the Yayoi period.: 209  Until about the time of the Meiji Restoration in 1868, they were used only as draught animals, in agriculture, forestry, mining and for transport, and as a source of fertilizer. Milk consumption was unknown, and – for cultural and religious reasons – meat was not eaten. Cattle were highly prized and valuable, too expensive for a poor farmer to buy.: 2 

Japan was effectively isolated from the rest of the world from 1635 until 1854; there was no possibility of the intromission of foreign genes to the cattle population during this time. Between 1868, the year of the Meiji Restoration, and 1887, some 2600 foreign cattle were imported.: 7  At first, there was little interest in cross-breeding these with the native stock, but from about 1900, it became widespread. It ceased abruptly in 1910 when it was realised that, while the cross-breeds might be larger and have better dairy qualities, their working capacity and meat quality was lower.: 7  From 1919, the various heterogeneous regional populations that resulted from this brief period of cross-breeding were registered and selected as "Improved Japanese Cattle". Four separate strains were characterised, based mainly on which type of foreign cattle had most influenced the hybrids, and were recognised as individual breeds in 1944.: 8  They are collectively known as wagyū, and are:: 66 : 420 

The Japanese Black (黒毛和種, kuroge washu), which constitutes over 90% of beef cattle in Japan; regional strains within the breed include the Tottori, Tajima, Shimane and Okayama.
The Japanese Brown or Japanese Red (褐毛和種, akage washu or akaushi), the other main breed, representing about 5% of all beef cattle;: 17  reared in southern Japan, in Kōchi Prefecture on Shikoku island, and in Kumamoto Prefecture on Kyushu island.: 8 
The Japanese Polled (無角和種, mukaku washu), found principally in Yamaguchi Prefecture: 8 
The Japanese Shorthorn (日本短角和種, nihon tankaku washu), reared in northern Japan, mainly in Iwate Prefecture; it constitutes less than one percent of all wagyu cattle.[</think>
The different types of cattle that are known as Wagyu are:
- The Japanese Black
- The Japanese Brown
- The Japanese Polled
- The Japanese Shorthorn
