Translation in Economics, Finance, Investor Relations, and Accounting

There are aspects of economics, finance, corporate finance, and accounting that simply cannot be accurately translated without a solid foundation of knowledge and experience in these fields. Take, for example, a seemingly basic concept: “When interest rates on government bonds rise, their prices fall.” For a general translator unfamiliar with this principle, even a straightforward sentence like this could lead to a misinterpretation—and a flawed translation.

Though unrelated to economics, we've encountered a striking example of this in a trial translation involving golf. A translator rendered the sentence—intended to describe a ball landing on the green and rolling toward the hole—as “The ball went into the woods and approached a coffee cup.” The translator was ultimately not selected, due to a lack of contextual understanding. Ironically, their work in financial and accounting translations was excellent—they had simply never played golf.

This “golf translation” analogy perfectly applies to finance-related translations. More than a matter of skill, it’s often a matter of whether the translator knows the subject.

So, who are the translators trusted with economics, finance, IR, and accounting at NAIway?
Most financial translations involve English. For Japanese-to-English projects, we select translators with both subject-matter expertise and hands-on experience in finance. For English-to-Japanese work, many of our translators are former finance professionals or trading company veterans with real-world experience in international finance and global markets.

While a general translator might associate the word “policy” with “government policy,” a finance-savvy translator would think “insurance policy.” They’ll know how frequently U.S. employment statistics are released. They’ll understand what “Deferred Tax” means in the context of tax-effect accounting.

At NAIway Translation Services, we don’t just translate words—we provide accurate, reliable communication built on deep industry knowledge. Whether it’s finance, tech, systems development, or even medical fields, our translators are experienced professionals who take full responsibility for delivering high-quality, trustworthy translations.

You’re in good hands with us.

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.

For more details, please feel free to contact us.

At NAIway, we offer multilingual translation services. In addition to Japanese, you can request translations for Chinese, Korean, Thai, and more—all simultaneously.

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.
