Toby Fox Explains Language Barriers Behind Undertale and Deltarune Localizations
Toby Fox explained on Bluesky that Undertale has no official translations beyond Japanese because he wants translations to match his vision and worked closely with a translator for Japanese; translating Deltarune into other languages isn’t feasible development‑wise, as it could delay releases. While some fans defended the decision, Fox suggested he may pursue different localization approaches in the future but offered no guarantees.
