Let the power of language be on your side!

We communicate with other people through kotoba, or language. Even though there are many different ways to communicate all over the world, kotoba is the main tool of human interaction. It is the foundation of speaking and thinking.
At NaGA International, we provide you with the best quality language instruction and services, opening you up to the wonderful world of communication.

Translation / Proofreading / Interpretation / Teacher outsourcing


Receive excellent quality work for a reasonable fee.

Receive excellent quality work for a reasonable fee on documents such as posters, pamphlets, business cards, or any other materials, in large or small quantities. We will provide you an estimate for free. Our achievements include translating documents from clients such as the Executive Committee for the Special Olympics, Shinshu University, and the Japan Junior Chamber, among others.


Have your document properly and professionally proofread.

Many shops and companies post signs in English these days. English signs are linguistically friendly to foreigners and portray a stylish image. But did you know that many Japanese-English words and phrases, which we use often and freely, are strange or incorrect in the eyes of a native speaker? Using the wrong English words or phrases may damage the image of the shop or company. Our proficient, professional proofreaders are native speakers who check spelling and grammar, and choose appropriate words for your documents.


Our interpretation service comes with a 100% satisfaction guarantee.

Our excellent interpreters are active on the front lines and have experience in working for the Nagano Winter Olympics, international conferences, and various  other events. Our interpretation services range from guided tours to conferences, business negotiations to speeches, and are designed to meet your needs (e.g., simultaneous, consecutive, and whispering interpretation).

Teacher outsourcing

Our teacher outsourcing service is flexible to fit your requirements.

We outsource our teachers to English, French, Chinese, Korean, and Japanese language seminars. Improve your staff’s language skills to boost communication and reduce conflict. Our teachers can be outsourced to company language seminars as well as to individual groups. Feel free to inquire for further information.
