Benefits of using generative AI for translation

Our new translation service utilizing generative AI compensates for "misinterpretation of context" and "unnaturalness due to literal translation" that often occur in machine translation, refining the translated text to a practical level.
For example, in addition to pointing out mistranslations, we can polish the text for more natural expression, unify the writing style, and suggest rewrites based on the field of use.
Furthermore, by having humans perform final adjustments based on context, cultural background, and field, we provide translations with quality close to human translation at a low cost and with speed.

Case Study Customer Testimonials and Implementation Examples

  • Chikyu no Arukikata
    "GOOD LUCK TRIP"

    As this is a medium for visitors to Japan, a literal translation would not convey its appeal, and it also required "fit" and "readability" based on the premise of print (DTP).
    Therefore, we created translations that can be used in accordance with multilingual page designs while adjusting expressions to suit the tourism context.

  • Ministry of Health, Labour and Welfare (My Site Translation)

    We needed to handle a large volume of approximately 600,000 characters across the entire website in a short period, while also maintaining consistent terminology and expressions for ongoing updates.
    Therefore, we utilized translation support tools to reference past translations and unify terminology and style, achieving both quality and speed.

    Ministry of Health, Labour and Welfare (Website Translation)
  • Official Website of a Railway Company in the Kansai Region

    There are many proper nouns such as route names and station names, where mistranslations or inconsistencies directly affect the user experience. Furthermore, information for inbound tourists requires accuracy to avoid any misunderstandings.
    Therefore, before starting the translation, we established a translation policy to organize the handling of proper nouns and used translation support tools to ensure the unification of terminology, thereby preparing the multilingual site for stable operation.
