Hokkaido Umamusume Farm (not my idea)

The life of an uma is defined by victories, draws, and defeats. Pride and fanaticism are expressed in moderation, like a cup of tea in the morning. Although there are special occasions, it's not uncommon to see these uma girls competing in high-level competitions around the world, and Japan is no exception. Stories of Uma girls who achieved greatness, and those who didn't, ultimately end in one place: a retirement farm. After years of racing and winning, all umas are retired to a specialized farm where they can live a peaceful and orderly life, free from worries and outside interference. Until the day comes when they become active again.
