NAIway AI Translation x Check
Fast, affordable, and we even go a step further—using generative AI like ChatGPT not just for translation, but to craft emotionally resonant Japanese copy that truly speaks to local audiences.

In Japanese-English and English-Japanese translation, AI can achieve up to 97% accuracy when applied to suitable fields or well-structured source texts. However, in real-world professional translation, accuracy often falls below 90%. With NAIway’s “AI Translation + Expert Review”, we refine AI-generated translations (mainly for Japanese-English and English-Japanese—other languages available upon request) by:
✅ Eliminating AI-specific errors to deliver high-quality translations with faster turnaround times and lower costs, surpassing conventional translation standards.
✅ Having experienced translators thoroughly review the output against the original text.
Looking to break into the Japanese market but want to keep translation costs low?
Say your company is aiming to localize content—websites, brochures, or marketing assets—for Japan. You're thinking of using AI translation tools like DeepL, Google Translate, or ChatGPT to cut costs. But there's a problem: you don’t have someone in-house who truly understands Japanese well enough to review, refine, and adapt that output into something that resonates with a Japanese audience.
Translating into Japanese isn’t just about swapping words—it's about navigating entirely different sentence structures, cultural nuances, and communication styles. That’s why these “quiet but critical” steps matter:
✅ Rewriting for natural flow and clarity
✅ Adjusting tone and expressions to match native Japanese sensibilities
That’s where NAIway Translation Service comes in.
With 30 years of multilingual translation experience and a solid base in Japan, we specialize in taking AI-translated content and elevating it, polishing it into native-level Japanese that actually works in the Japanese market. From localization to compelling copywriting tailored for Japan, we bridge the gap between raw AI output and market-ready communication.
We even go a step further—using generative AI like ChatGPT not just for translation, but to craft emotionally resonant Japanese copy that truly speaks to local audiences. From rewriting to copy creation, we take on the heavy lifting to ensure your message hits home in Japan.
Multilingual Translation Support
At NAIway, we offer multilingual translation services. In addition to Japanese, you can request translations for Chinese, Korean, Thai, and more—all simultaneously.
This eliminates the hassle of working with multiple translation providers for different languages. And of course, we ensure high-quality translations in every language we offer.

NAIway's Quality Assurance System
At NAIway Translation Service, we believe that quality management is our top priority as a professional translation company. To ensure the highest standards, we have developed our own Quality Assurance System (QAS) and implement strict quality control measures.
For high-quality Japanese-Spanish and Spanish-Japanese translations, every document undergoes a two-step review process: after the initial translation, a second translator conducts a thorough quality check.
We meticulously review each character and sentence, ensuring logical flow, terminology consistency, and appropriate expressions to deliver a refined translation tailored to your needs.

The History of NAIway Translation Service
NAI Corporation was founded in September 1995—an era when the internet was still largely unused outside of select academic fields.
Pioneering the industry, NAI was among the first to offer online editing services for academic papers by leading researchers from Europe and the United States. Since then, we’ve supported over 10,000 researchers by providing English proofreading, translation, and a wide range of on-demand services required throughout the publication process.
Allow us a moment of pride: We are honored to have contributed to the success of many of Japan’s most prominent scientists. Our unwavering commitment to quality in scientific editing and translation has earned us recognition as a trusted leader in academic support—and that legacy continues to this day.
In 2002, our translation services division branched out under the name NAIway Translation Service. Since then, we have expanded beyond English and Chinese to offer multilingual solutions in over 50 languages, including major European languages (French, German, Spanish, Italian, Portuguese) and Asian languages (Vietnamese, Indonesian, Thai, Malay, Burmese, Korean, and more). As a bridge between cultures and industries, we continue to provide comprehensive language solutions with translation at our core.
At the heart of NAIway lies the DNA cultivated from years of working with scientific manuscripts—where even the smallest error, misinterpretation, or overconfidence can be fatal. That same level of precision and integrity now powers our work across a wide range of industries: medical and healthcare translation, scientific and technical content, SDS translation, multilingual survey localization, and legal or contractual documents.
Our philosophy is simple: total commitment to quality, backed by deep expertise and relentless attention to detail. This is what makes NAIway the translation partner of choice.
