Umamusume Name Generator

Every Umamusume is named after a real Japanese racehorse, so a convincing original horse girl needs a name that could pass on a JRA race card. Registered names are capped at nine katakana characters (roughly eighteen Latin letters including spaces), which is why canon names are short and punchy: Gold Ship, Rice Shower, Vodka, Tokai Teio. Most are English words written in katakana, but the pool also includes French, Italian and German (Orfevre, Gentildonna, Rhein Kraft), pure Japanese (Haru Urara, Yukino Bijin) and deliberately silly entries like Matikanefukukitaru.

The strongest stylistic tell is the owner prefix. Japanese stables stamp their horses with a house word, so Mejiro, Symboli, Narita, Admire, Satono, Daiwa, Sakura, Meisho, Agnes, Hishi and Tosen all precede an ordinary noun: Mejiro McQueen, Satono Diamond, Agnes Tachyon. Pair a prefix with a fresh second word and you instantly sound like part of the same paddock. The other big patterns are two-word English images (Special Week, Silence Suzuka, Manhattan Cafe), single evocative words (Duramente, Transcend) and music terms, which real owners love.

This list mixes canon horse girls with original names in every one of those registers, so you can pick a trainer's roster, a rival for your fanfic, or a name for your own horse girl OC that sounds like it belongs in Tracen Academy.
