List of Japanese horse breeds

This is a list of the horse breeds usually considered to be native to Japan. Some may have complex or obscure histories, so inclusion here does not necessarily imply that a breed is predominantly or exclusively Japanese. In Japanese, this breed group is called "kokunaiuma".(国内産馬, domestic horse)

Crossbreeds
There are also five crossbreeds that have been developed from existing breeds:
 * Japanese Draft (日本輓系種)
 * Japanese Sports Horse (日本スポーツホース種) - Equestrianism, general riding
 * Japanese Riding Horse (日本乗系種) - Equestrianism, general riding
 * Japanese Pony (日本ポニー種) - General riding
 * Japanese Miniature Horse (日本ミニチュアホース) - Pet

Current crossbreed names were established in 2003, and the general breed classification "乗系種" (riding horse) was split into Sport Horse and "normal" riding horse.

There is also a sixth crossbreed definition, heavy crossbreed (輓交種), defined 2007 solely for the purpose of determining the proper registry for a foal.
