English to Japanese and Japanese to English

Japan is one of the world’s largest and most important markets, and it is known for its predilection for high quality products. This trait is particularly evident in translation and localization projects where the quality of your translation can determine the success of your product. We know the Japanese market particularly well and we have access to the very best native Japanese and English translators and interpreters.

Clients with Japanese or English translation or interpreting needs come to JLS because they know we provide the level of personalized care not found in large corporate agencies. They know they can count on the expertise and ability of our accounts managers and project management teams to handle not only high-volume translation projects, but also demanding interpreting assignments as well.
