About This Translation

This mod adds Japanese language support to Solasta 2, translating approximately 14,500 strings (~140,000 English words) into Japanese. It covers story dialogue, character descriptions, UI, menus, D&D 5th Edition rules text, tutorials, item descriptions, quips, and more.

This translation was generated using AI with a custom pipeline that includes a D&D terminology glossary, scene context analysis, character speech profiles, and per-line speaker metadata. It is not a professional human translation — you may encounter occasional awkward phrasing or inconsistencies.

Translation Coverage

Main Campaign Dialogue — ~4,900 strings, fully covered
D&D Rules & Abilities (SRD5) — ~2,900 strings, fully covered
UI, Menus & System — ~2,500 strings, fully covered

Known Limitations

Hardcoded strings

A small number of UI elements compose text programmatically, bypassing the localization system.

Early Access updates

As the game is updated, new strings will appear untranslated until the mod is rebuilt.

~114 strings (0.9%)

Remain in English — mostly short format strings or strings identical in both languages.

FAQ

Does this work with other mods?

Generally yes. This mod only adds a new language and doesn't modify existing game files.

Will this break my save?

No. Language is a display setting only — switching languages does not affect save data.

The game updated and some text is English again.

Game updates may add or change strings. Check for an updated version of the mod.

Can I help improve the translation?

Yes! If you spot errors or awkward phrasing, please report them. Community feedback is invaluable.
