Corporate Information


At UMI, we have been engaged mainly with multilingual translation of more than 30 languages for more than 10 years.

In this age of information overload, a gap has arisen between the information the consumer seeks and the information that enterprises provide.

In order to offer service with recognized value, it is of the utmost importance to find keywords that resonate with the target audience and easily understood words that create a common language.

With professional careers spanning more than 10 years, our staff are highly proficient at selecting appropriate words and work in conjunction with native speakers to provide translations and writing that meet clients’ needs. Our main business of providing translations and writing for business is led by female staff with a global perspective. Translations are carried out by professionals with more than 10 years’ experience, including Japanese nationals who grew up overseas and foreigners with high levels of Japanese ability. Their work is then proofed by professionals who are familiar with the local situation, following which proofreaders perform a final check. Japanese translations are checked by professional writers who are familiar with the industry in question and have specialized knowledge. With high quality multilingual translation specializing in “words” as our advantage, we offer direct, effective messaging.
