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.[4]: 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.[5]: 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. Among the various heterogeneous regional populations that resulted from this brief period of cross-breeding, four separate strains were characterised, and were recognised as breeds in 1944. These were the four wagyū breeds, the Japanese Black, the Japanese Brown and the Japanese Polled and the Japanese Shorthorn.[5]: 8
The Mishima is one of two small isolated groups which escaped the process of hybridisation; the other is the Kuchinoshima breed from Kuchinoshima island in the Tokara Island group. Together they represent the only surviving remnant of the native cattle population of Japan.[3]: 51

These are the cattlebreeds considered in Japan to be wholly or partly of Japanese origin. Inclusion here does not necessarily imply that a breed is predominantly or exclusively Japanese.
