The Japanese Brown (Japanese: 褐毛和種, Akage Washu or 赤牛, Aka Ushi) is a breed of small Japanese beef cattle. It is one of six native Japanese cattle breeds,[2] and one of the four Japanese breeds known as wagyu, the others being the Japanese Black, the Japanese Polled and the Japanese Shorthorn.[3]: 420
All wagyu cattle derive from cross-breeding in the early twentieth century of native Japanese cattle with imported stock, mostly from Europe.[4]: 5 In the case of the Japanese Brown, the principal foreign influence was from the Korean Hanwoo and Swiss Simmental breeds.[1]
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.[5]: 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 fertiliser. 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.[4]: 2
Japan was effectively isolated from the rest of the world from 1635 until 1854; there was no possibility of 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. At first there was little interest in cross-breeding these with 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. 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 breeds in 1944. These were the four wagyu breeds, the Japanese Brown, the Japanese Black, the Japanese Polled and the Japanese Shorthorn.[4]: 8
In 1960 the total breed population was reported to be over 525 000.[4]: 23 In 1978 it was reported as 72 000, and in 2008 it was 18 672.[1] The Japanese Brown constitutes about 4.8% of the national beef herd.[6]: 17 The conservation status of the Japanese Brown was listed by the FAO as "not at risk" in 2007.[7]: 71
A small number were exported to the United States in 1994.[8]
