Quality Pursuit

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.
Challenges and Risks of Relying Solely on AI Translation
While AI translation is fast and cost-effective, critical mistranslations, hallucinations, and a lack of cultural context can pose significant legal liabilities and compromise your company's credibility.
| Target Documents & Fields | Potential Risks & Issues of AI | Setany Alpha’s Solution |
|---|---|---|
| Contracts, Legal & Official Documents | Misinterpretation of clauses and legal terms leading to contractual disputes or liability claims. | ISO 17100-compliant translators and legal experts thoroughly verify contractual context and legal consistency. |
| Technical Manuals & Engineering Specs | Mistranslation of technical terminology and AI hallucinations causing operational errors and safety hazards. | Specialists in physics and chemistry (graduates of the University of Tokyo & Kyushu University) cross-check with official standards and primary literature. |
| Workplace Regulations for Foreign Staff | Literal translations missing subtle nuances, failing to communicate Japanese labor practices and causing workplace disputes. | Native editors familiar with cross-cultural business and labor regulations rewrite policies into clear, unambiguous guidelines. |
| Global Websites, IR & Corporate PR | Unnatural phrasing and lack of industry idiom degrading brand prestige and credibility in overseas markets. | Refined native polish tailored to local business sensibilities ensures persuasive, professional messaging. |
