Start Your Free Accurate Translation“This tool's accuracy from Japanese to Korean, even for specialized fields like legal or patent documents, is on par with a professional human translator. It gets all the subtle differences—such as legal terms under South Korea's Civil Act or technical regulations from the Korean Intellectual Property Office—that standard machine translators repeatedly get wrong.”Dr. Kim Jihyun, PhD, Korean Society of Translators (한국번역가협회) Certified Member

Guarantee Perfect Accuracy with a Free Custom Dictionary
Business, law, or engineering, your specific term choices matter. Our Custom Dictionary allows you to lock in your preferred Korean translation for brand names, technical jargon, and industry expressions. Maintain 100% consistency—for free.
Brand Integrity
Keep company and product names consistent—never translate 'ユニクロ' as anything other than '유니클로'.
Technical Precision
Define unique Korean translations for specialized terms. For example, always render '特許請求の範囲' as '청구항', not the literal '특허청구범위'.
Industry Standards
Force the usage of industry-approved Korean words. E.g., legal: '民法' as '민법', not '시민법'.
Consistent Phrasing
Set legal clauses, disclaimers, or business taglines precisely as your organization prefers. E.g., always translate '以上、よろしくお願い申し上げます。' as '이상입니다. 감사합니다.'

Legal & Business Contracts
Scenario:
