Translation requires more than mere English skills; it requires advanced Japanese language skills, specialized knowledge, and the skill to accurately grasp the original writer's intentions and articulate them in a way that is understood by the reader.

Although cheap translation services may save you money, they are meaningless if their translations are difficult for the reader to understand. Here at KARIS, therefore, we translate what the writer of the original text wants to convey in a way that the reader can fully understand. Our translation services cover a wide range of materials, from daily use materials such as news articles and lyrics, to practical materials such as presentation materials and contracts, to academic materials such as English essays and medical dissertations.

Our lead translator holds two Master's degrees from the graduate schools in the US and UK; has over 10 years' practical translation experience; has worked for four companies overseas; and has United Nations Associations Test of English SA Class, EIKEN Grade 1, TOEIC 980, and VERSANT 72 and many more qualifications. Currently, he serves as an English translator, supporting many companies and individuals with English language needs. He started this service to meet the translation needs of people like you.
