Jeju Island has been the home to the Jeju Island Horse for as long as 5,000 years or longer.
The early inhabitants hunted the horse for food. Many jaw bones have been found in shell mounds and early stone age sites. As to how and when the Jeju Island Horse arrived on Jeju Island, the general belief is some time between the Ice ages when the water level was much lower and a land bridge extended possible as far as Japan. At least three sub species are or where until recently found on Japan.
Gene studies indicate that this is a domestic horse with little or no cross or in breading with any modern horse.
Due to the small number of Jeju Island Horses they are listed as ENDANGERED, the island is small and space for horses is limited and economic pressure for land is reducing grazing land.
