Rozetta Secures Top Market Share in Japan's Translation Industry for Fourth Consecutive Year

Rozetta Corp., a subsidiary of Metapsi Group that develops and provides high-precision industrial translation AI, announced that it has secured the No. 1 position in vendor sales share in the translation market (based on fiscal 2024 results and 2025 forecasts) according to the 'ITR Market View: Generative AI/Machine Learning Platform Market 2025' report published by ITR.

Challenges in 'Translation Quality' in the Generative AI Era

With the rapid adoption of generative AI, translation has become easier than ever. However, in corporate practice, there is a growing demand for 'translation quality' that goes beyond simple natural text generation, focusing on requirements such as 'unified terminology,' 'consistency with past documents,' and 'quality assurance.'

Particularly in fields like manufacturing, IT, pharmaceuticals, and law, even minor mistranslations can lead to significant risks, making high translation quality essential.

Recognition as 'Industrial-Grade Translation AI' Drives Share Expansion

Against this backdrop, Rozetta believes its high-precision industrial translation AI, 'T-4OO,' has earned the top domestic market share due to its high practicality in corporate translation workflows.

While general-purpose generative AI excels in 'natural text generation,' T-4OO distinguishes itself as an 'industrial-grade translation AI' through the following features:

- High-precision translation specialized for professional documents (manuals, contracts, technical documents, etc.) - Translation reproducibility through unified terminology and reference reflection - Quality assurance through AI-assisted translation verification - Extensive implementation record in highly specialized fields such as manufacturing, IT, and pharmaceuticals

These features have contributed to an implementation record of over 6,000 companies.

Comment from Atsunori Shinoda, Development Manager for 'T-4OO'

'While generative AI has made translation a task that anyone can do, 'translation that requires no human post-editing' has not yet been fully realized. We identify this gap as the biggest challenge for enterprises and are working towards realizing a 'translation AI that requires no human post-editing.' This No. 1 market share is a result of being evaluated from the perspective of 'whether it can truly be used in corporate practice' rather than just translation accuracy. Moving forward, we aim to further improve translation accuracy, complete this 'translation AI that requires no human post-editing,' and fundamentally change the way corporate translation work is handled.'

Future Outlook

We are committed to completing a fully 'human-editing-free' translation AI as soon as possible.

About 'T-4OO'

'T-4OO' is a high-precision industrial translation AI that fuses customizability for professional documents and internal terminology with the fluency of generative AI. Unlike traditional industrial or professional translation, it offers a 'High Precision' mode that allows users to accurately reflect their internal translation assets, styles, and expressions without building expensive proprietary engines. It also features a highly acclaimed 'Ultra-High Precision (Deliberate)' mode, which dramatically improves translation accuracy through Agentic AI.

About 'Ultra-High Precision (Deliberate)' Mode

Equipped with Agentic AI, this mode dramatically improves translation accuracy, reducing the need for human sentence-level corrections to 0.05%, essentially realizing near-total automated translation. Furthermore, it identifies potentially mistranslated sections, highlights them, and displays accompanying comments to significantly streamline the translation verification process.
