After looking through the IRL pedigrees of a lot of the umas on the uma musume wiki, I have discovered that none of them are actually Japanese horses. They're all from GB, USA, FR, or a few other western countries. So why are the umas so small? They should be of European height.

Tokino Minoru, for example, has 15 out of 16 great-grandparents from GB and 1 from FR.
