Efforts for
high-quality translation
Quality Pursuit

While the rise of AI translation has achieved substantial speed and cost reductions, Setany Alpha's specialists and native editors thoroughly inspect and verify texts to eliminate machine translation errors and contextual discrepancies, delivering reliable quality. We also provide 100% human translation without relying on AI or machine translation.

Excellent translation
Proven Satisfaction

Prioritizing "High Quality (Exhaustive Research & Editing)", "Speed & Cost (AI Optimization)", and "Performance (Compliance with Public & International Standards)", we deliver optimal solutions tailored to your unique requirements.

Addressing Critical Risks in AI Machine Translation

While AI translation tools offer speed, technical mistranslations and cultural blind spots can lead to legal disputes and brand damage.

Domain / Document Potential AI Risks & Pitfalls Setany Alpha's Solution
Contracts & Legal Documents Misinterpretation of legal terms or rights may cause international disputes, breach of contract, or financial liabilities. ISO 17100 compliant linguists and legal specialists verify clause coherence and enforce strict legal consistency.
Technical Manuals & Specs Terminology errors or AI hallucinations can lead to on-site operational hazards, manufacturing delays, and loss of trust. Engineers and scientists (Univ. of Tokyo / Kyushu Univ. alumni) cross-check against official international standards.
Work Regulations & HR Literal translations fail to communicate nuanced Japanese labor practices, leading to costly workplace misunderstandings. Native editors thoroughly versed in cross-cultural HR adapt policies into clear, respectful, and legally sound texts.
Websites, IR & Global PR Grammatically correct yet stiff or awkward phrasing damages corporate reputation and undermines investor confidence. Native business specialists polish phrasing to ensure compelling, natural rhetoric that resonates with global stakeholders.
