Has introduced many quality broodmares from abroad with the aim of producing high quality racehorses. Foals are turned out nightly together with their dams until they are weaned in the autumn.
Weanlings，yearlings，horses in pre-training as well as racehorses out of training are stabled here.
Young horses are turned out nightly in all seasons so as to grow strong and tough.
Horses in training are nurtured to be successful racehorses at these impressive training facilities using mainly the roofed up-hill course at Tohno Stable.
