Guarantee Perfect Accuracy with a Free Custom Dictionary
True accuracy means using your exact terms and preferences. Lock in your brand, key terms, or specific industry language. Ensure all your Spanish-to-Japanese translations use the right word—every time and in every document. Absolutely free.
Brand & Product Consistency
Guarantee brand names (e.g., 'Santander') stay as ブランド名サンタンデール—not mistranslated as サンタンデール銀行 (if not appropriate) or genericized.
Industry/Technical Precision
Lock technical terms correctly: e.g., Spanish 'ingeniero de software' as ソフトウェアエンジニア, avoiding literal/awkward translations like ソフトウェアの技師.
Jurisdictional Consistency
Ensure Japanese legal entities map to correct forms: 'Sociedad Anónima' to 株式会社 (かぶしきがいしゃ) rather than simply 会社.
Slogan & Formula Retention
Fix set phrases: For example, 'Contigo, hasta el final' always becomes 'あなたと最後まで', not a literal/awkward rendering.
Accurate Translations for Every Profession
Avoid critical errors in business, technical, and legal translations for the Japanese market or clients in Japan. Our AI is custom trained on Spanish–Japanese domain data for perfection in high-stakes scenarios—try free.
Corporate & Legal
Scenario:
Translating a distribution agreement between a Barcelona exporter and a Tokyo-based client.
Challenge:
Mistranslating specific legal wording—like not properly localizing 'cláusula de arbitraje' to 仲裁条項 per Japanese company law—can invalidate contracts before Japanese courts.
Solution:
Our AI is trained on Japanese and Spanish contract law corpora, preserving intent and context for enforceability under Japanese jurisdiction.
Finance & Trade
Scenario:
Converting an annual financial report from Madrid for use at Sumitomo Mitsui Banking Corporation, Tokyo.
Challenge:
European number formats, fiscal year language, or investment terms can be misread without careful localization. Japanese financial reporting has unique conventions and strict format.
Solution:
Our AI localizes tables, jargon, and industry codes (SIC, NISA) to Japanese FSA/金融庁 specifications; financial comments are rendered natural and precise.
Manufacturing & Tech
Scenario:
Localizing a Spanish instruction manual for SONY's logistic partners in Nagoya.
Challenge:
Safety warnings or workflow procedures must not be directly translated—Japanese expects passive/impersonal phrasing. Formatting for double-byte characters (全角) and annotation is critical.
Solution:
Leverage a custom dictionary to standardize technical terminology; our AI respects Japanese formality hierarchy (です・ます, である) and corrects for industrial documentation style.
