Part 1: What is Umamusume Pretty Derby

Umamusume: Pretty Derby is a Japanese multimedia phenomenon from Cygames, blending anime, manga, music, and a free-to-play simulation game. The characters—anthropomorphized as “horse girls”—race and train toward competing in events like the Twinkle Series. The original Japanese mobile version launched in February 2021, amassing over 30 million downloads across Asia. Its standout appeal lies in character-driven training simulation, rich storytelling, and strategic gameplay elements like stat balancing, race tactics, and event choices.

The franchise also includes multiple anime seasons: the original aired in 2018, followed by seasons in 2021 and 2023, plus spinoff content and a May 2024 film. On June 26, 2025, Cygames released an official English version on iOS, Android, and PC via Steam and Google Play Games . It features cross-platform sync, faster pacing, launch-ready features (jukebox, landscape mode), and global music streaming.

As a PC game enthusiast, you’ll find it accessible via Steam with high-resolution graphics and mod-friendly formats. On mobile, it's stable and optimized for long sessions. Yet for English-speaking players, especially on the PC version, third-party translation tools still offer value for mods, fan patches, and additional languages.

Part 2: What Languages Does Umamusume Pretty Derby Currently Support?

The official English release (June 26, 2025) supports English only, featuring:

• Fully English menus, UI, story, and events.
• Immediate English audio (where applicable) and translated character music.

Prior to English’s arrival, the Japanese version included Japanese only, leading to a dedicated fan community creating translation patches.

One of the most notable is the “UmaTL” translation project on GitHub. It includes a toolset for the Windows (DMM) version—also usable in Linux and macOS—that patches game files, translating everything from tutorials and race segments to live lyrics and UI via master.mdb, DLL hijacking, and Unity asset replacement.

Another mod—Carotene/Hachimi—is an all-in-one fan-made translation patch available for both Windows and Android. These tools are independent from the official English release and filled gaps such as more polished dialogue, fan-verified terms, and nuanced character text. They remain valuable for multilingual fans or those interested in detailed fan translations.

While Japanese versions still dominate outside Asia, the official English version now provides comprehensive localization. Still, fans wishing to inject additional layer translations or polish may prefer combo usage of official version plus fan toolsets.
