T-400 AI Translation Tool Expands Multilingual Capabilities

On June 19, 2026, Rosetta, a leading AI translation service provider in Japan, announced significant enhancements to its high-precision industrial translation AI tool, T-400. This update expands its bilingual functionality by adding nine major languages from Asia and Europe, thus broadening its multilingual support significantly.

Expanded Language Pairs

Previously, T-400's translation capabilities were limited to Japanese, English, and Chinese (both simplified and traditional). However, with this latest update, users can now access the translation feature between the following languages:

Southeast Asian Languages:

• - Vietnamese
• - Thai
• - Indonesian
• - Burmese

European Languages:

• - Spanish (both European and South American)
• - German
• - Portuguese (both European and South American)
• - French
• - Italian

The new language pairs can be utilized through the ‘Reference Translation’ feature, enabling users to harness the power of existing translation assets.

Leveraging Translation Assets Across Languages

The incorporation of these new languages allows Rosetta to harness its accumulated translation assets and expression rules developed from Japanese, English, and Chinese to be applied more broadly. The expected benefits from this extension include:

• - Stabilization of quality through the reuse of previous translations
• - Strengthening of terminological consistency
• - Mitigation of translation discrepancies in multilingual projects
• - Reduction in the labor required for post-translation checks and corrections

This is particularly advantageous for documents such as manuals and user guides, which often face high demand for multilingual dissemination.

Comments from T-400 Development Lead, Atsunori Shinoda

Atsunori Shinoda, the lead for T-400's development, expressed, “We have received numerous requests from clients wishing to utilize the translation function in additional languages. With this multilingual support, we can now leverage our previous translation assets over a broader range. We are committed to continue improving translation quality while enhancing convenience, ultimately contributing to elevated productivity in translation workflows.”

Future Directions

Rosetta is dedicated to ongoing improvements in translation quality and expansion of multilingual support within T-400. The company is open to feedback, encouraging users to submit requests concerning further language additions or specific applications they would like to see.

About T-400

T-400 combines the customization needed to replicate specialized documents and corporate jargon with the fluency offered by generative AI, positioning it as a leader in high-precision industrial translation. Unlike traditional industrial and specialized translations, it allows users to reflect internal translation assets accurately, without the need for expensive proprietary engines. The ultra-precise ‘Deep Consideration’ mode, featuring agentive AI, has gained acclaim for its dramatic improvements in translation accuracy, effectively reducing the necessity for sentence-level corrections to an impressive 0.05%. This mode identifies potentially mistranslated sections and highlights them for easy review, streamlining translation checks immensely.
