In the central government Hyomashi (Office of Military Horses) controlled farms all over Japan as well as public and private horse farms, and there was a system for governmental control over provision and management of riding horses, in which horses in the farms fit for riding were sent to the army and kept at a rich soldier's house and the other horses were used for ekiden.
中央では、兵馬司が、全国の牧と公私の馬牧を管理し、牧で乗馬に適するものは、軍団に送り裕福な兵士の家で飼育され、駄馬は、駅伝場として使用されるなど、国家によって騎馬の供給管理を統制するための仕組みがつくられていた。
