Rozetta Significantly Expands Supported Languages for 'Style Specification' in High-Precision Translation Mode for 'T-4OO' Industrial AI

Rozetta Inc. (CEO: Junichi Goishi), a developer and provider of Japan's No. 1 market share AI translation service and a member of the Metareal Group, announced on April 28, 2026, the expansion of supported languages for the 'Style Specification' feature available in the 'High-Precision Translation' mode of its industrial translation AI 'T-4OO.'

With this update, the style specification feature, which was previously limited to certain languages, is now available for translations from major Asian and European languages into Japanese. This allows users to pre-define the style and notation rules of translated text.

Expansion of Supported Languages in 'High-Precision Translation' Mode 'Style Specification' is a feature that allows users to designate the style and notation rules of the target text before translation, ensuring they are reflected in the results. For example, the following settings are possible: - Writing style (Polite 'Desu/Masu' vs. Plain 'Da/De aru') - Full-width vs. Half-width for alphanumeric characters - Notation of symbols and brackets - Punctuation style (e.g., 、。 vs. ，． vs. , .) This enables consistency across different purposes and media, drastically reducing the labor required for manual corrections after translation.

Newly Added Languages This update makes the style specification feature available for translation from the following languages into Japanese: [Southeast Asian Languages] - Vietnamese - Thai - Indonesian - Burmese [European Languages] - Spanish (European / South American) - German - Portuguese (European / South American) - French - Italian Previously, only limited pairs like Japanese ⇄ English and Chinese (Simplified/Traditional) → Japanese were supported. This expansion ensures higher translation quality and consistency across a broader range of multilingual environments.

Reducing 'Final Adjustments' in Translation Work In multilingual translation, challenges often arise not only in quality but also in 'notation inconsistency' and 'unifying writing styles.' With this feature, the following can be achieved at the translation stage: - Unifying the tone of internal documents - Adhering to notation rules for manuals and specifications - Optimizing the style for media and PR documents This leads to a reduction in final adjustment tasks previously performed manually.

Comment from Atsunori Shinoda, Head of T-4OO Development: 'In this update, we have significantly expanded the supported languages for style specification in high-precision translation. Particularly for translation from Asian and European languages to Japanese, being able to automatically reflect consistency in style and notation has greatly improved practical usability. Translation is not just about translating correctly, but how it is expressed. We will continue to aim to provide a translation experience that can be used directly in actual business operations.'
