Japan is one of the countries with the strongest economic development in the world, with a GDP of over 4,200 billion USD (2024). This country is not only notable for its population of over 124 million people and high labor productivity, but also as the birthplace of leading global brands such as SONY, TOYOTA, TOSHIBA, and MITSUBISHI. This creates an increasing demand for international trade and cooperation, which in turn drives a growing need for certified Japanese translation services.

What is certified Japanese translation?
Certified Japanese translation is the process of converting document content from Vietnamese to Japanese or vice versa, and then having it authenticated by a competent authority for accuracy and completeness compared to the original.
The certified translation process consists of two main steps: (1) Japanese translation and (2) Certification of the translation. Documents requiring certified translation must be completed by a translator with the proper qualifications and certificates, along with a registered specimen signature at the competent authority. Therefore, even if an individual translates the document themselves, the authorities will not accept it if the translator does not have a valid registered signature.
No.1 Translation is one of the providers offering certified Japanese translation services quickly and at an affordable price. Customers can contact the Hotline: 096.295.6006 for support or leave their contact information HERE, and we will get in touch within 24 hours.
