Horse maintenance costs are 100,000 yen for each horse on a farm and 400,000 yen for each horse in a stable. This fee is collected at the beginning of each month.

Furthermore, performance changes depending on factors such as sturdiness, fatigue recovery, condition, horse weight, and growth rate. If you have a bad temper, you'll be late, or you'll waste your stamina by moving ahead without following the instructions on the way. If you have a fighting spirit, it will be easier to win when competing in a straight line. If it is highly durable, it is less likely to break down during training or racing. There will also be fewer cases of athletes becoming unwell after a race. If you have a high level of recovery, it will be easier to overcome fatigue after a race, and you will be able to run tougher even if you run repeatedly at short intervals. The condition of a horse is what is called a biorhythm, and no matter how capable a horse may be, if it is put into a race when it is not in good shape, it will not be able to fully demonstrate its potential. Each type has a different peak time, with early maturing being around the middle of 4 years of age, normal being late 5 years of age, and late maturing around 7 years of age. Horses might by injured during races and in such cases they are excluded from next races. In extreme situations, when prognosis are poor, horse can be euthanized.
