Translation services that fuse diverse expertise
with technical knowledge

Taking into account our clients' needs, including the background and intended purpose of their translation projects, we deliver high-quality translation services that are optimized to bridge linguistic barriers in any business scenario.

Translators with professional expertise in specialist fields

We have a network of approximately 6,000 translators with professional expertise in a variety of specialist fields. We select an appropriate translator for each translation project based on the translation category and document type. For more complex translation categories, we ensure peace of mind for the client by cross-checking the translation.

Increased efficiency and quality through proprietary engineering technologies

Our engineers have developed tools that enable us to deliver high-quality translations efficiently and reliably. These tools allow us to complete translations expeditiously without sacrificing quality, thereby ensuring that we meet client needs in every project.

Our engineers develop and customize the necessary tools according to the individual project.
This improves the efficiency and quality of our translation work considerably.

Client-specific glossaries for improved translation accuracy

In accordance with the individual client's preferences, we create a glossary (database) of phrases and industry jargon that are commonly used in each project category. These databases are meticulously managed and updated to include client feedback, as well. This limits the risk of inconsistencies in the use of terminology and improves the translation accuracy.

Proprietary translation checking tools that prevent mistakes before they can happen

In large-scale projects that call for a high degree of expertise, our translation editors and proofreaders use our proprietary tools to ensure that numbers and symbols are accurately used and that the spelling is correct. This helps to eliminate mistakes that may otherwise go unnoticed.

Human resource training to ensure reliable, high-quality work

Ever since SunFlare's establishment, many of our registered translators have graduated from SunFlare Academy, a translation school that prioritizes translation quality. We provide regular training and client feedback to our translators, proofreaders, checkers, and every other member of our translation team, because consistently improving quality is one of our core goals.

— Relationship with SunFlare Academy —

SunFlare Academy caters to a variety of different lifestyles by allowing students to either attend lessons in person or learn via a correspondence course. Since our lessons feature practical content that can be applied in actual translation work for SunFlare, our students acquire a well-rounded knowledge base in a wide range of industry and business categories. Students who pass our Translator Qualifying Examination (TQE) are also entitled to register with SunFlare. To date, over 3,000 translators have registered with us through this system.

Translators: Regular training is conducted using samples

A translation workflow that satisfies client needs

SunFlare constructs translation systems that cater to the individual client's needs. Prior to every translation project, we meet with the client to clarify the project specifications and then select the optimal translator for the particular category. After the translation has been edited and proofread, the documents are generated using the client's choice of application. In this way, we are able to deliver documents that meet the individual client's needs, allowing them to be used immediately without further alteration.
