English to Japanese Translation

For all of our English-Japanaese translations, we only use experienced, native Japanese translators, all of whom specialise in a number of different areas of translation to give the best possible results for our customers. We then make sure the formatting is correct, which is particularly important for a language such as Japanese, providing a final Japanese translation of excellent quality.

Japanese (日本語) is one of the world’s biggest languages. It is spoken by around 130 million people, mainly in Japan. Due to the strength of Japanese trading, it is an extremely important business language. With Japanese, it is extremely important to use the right register, of which there are three: the plain form futsūgo 普通語), the simple polite form teineigo 丁寧語) and the advanced polite form (keigo 敬語). Rest assured that our translators will translate appropriately.

Japanese to English Translation

Whether your Japanese-English translation assignment is complex and jargon-heavy or more basic in style, Rosetta Translation always has experienced translators on hand to deliver, with expertise in a number of areas, from technical computer jargon to legal terminology.

As an internationally aware company, we operate as worldwide a service for our English translation as we do for our other languages. This means that we can provide English in any of the many existing dialects, whether you need British English, American English, Australian English, even Jamaican English, we have the know-how and the expertise.


Formatting in the Japanese language

Formal Japanese texts are often written from top to bottom, with multiple columns of text progressing from right to left. Literature, such as novels and poetry, as well as newspapers and non-fiction texts are some examples of documents in Japanese that are written this way. This produces a unique challenge when translating where matching the layout of the source text is an important way of conveying the meaning in the document itself. Our translators are well versed in making layout judgements on translations to ensure that the meaning of your text is portrayed correctly and faithfully, without losing any readability in English.


The origins of the Japanese language and what this means for your translation

Surprisingly, although Japanese has loaned Chinese characters in its written language, it does not have any genetics based in the language. This is because Japanese is part of the Japonic family of languages and was only spoken and rarely written in a way we would find recognisable today before the Heian period (794-1185AD). The Chinese language was spoken and written in Japan as a means to communicate between China and the Japanese court during diplomatic missions, meaning that it was readily present in Japan around the time we start to see a record of kanbun, a writing system that used Chinese characters along with diacritical marks which allowed Japanese speakers to read Chinese sentences by changing the word orders and applied Japanese grammar. From kanbun to what we know Japanese to be today, there has been a big leap.  The Japanese of today has three distinct alphabets which are used together interchangeably and simultaneously to convey tone, vocabulary and grammar; hiragana (the phonetic lettering system), katakana (commonly used to transcribe foreign words) and kanji (symbolic characters from Chinese script).

Understanding which alphabet to use is essential in ensuring your translation hits the mark. One of the key considerations is the age of your audience as Japanese citizens learn the three alphabets progressively as they go up through primary and secondary school, so if you’re translating a children’s novel, the alphabet you would use would have to be appropriate to their reading age, and conversely; a piece of prose aimed at a more mature audience would seem odd for readers to be written in a hiragana, meaning the original tone would not be respected.

Whether translating into or out of Japanese, we will only every use a native level speaker of your target language, meaning you can rest assured that such difficulties in conveying the tone and feel of your text are handled with the upmost skill so you can relax knowing that we are taking care of it.


Interpreting from Japanese into English and vice versa

While Japanese has the fastest spoken rate, it also is reported to have the lowest amount of information density per second in a recent study conducted by the Université de Lyon. This means that, with regards to Interpreters (those who translate orally the words of a person speaking a different language), certain challenges arise.

Boiled down, this means that while much is being said, not a lot of information is being given (which is not that surprising when you consider it as it takes almost eight syllables just to say “not” in the simple polite form of Japanese). There is also a distinction between word order in Japanese and English; Japanese being a subject-object-verb language and English being a subject–verb–object language. Seems like a simple difference, right? However, the implications are significant as the difference in word order means a further delay in the lag time between the interpreter listening to the speaker and being able to produce the aural translation. This mismatch in word order makes interpreting from Japanese into English slightly easier than Japanese into English.

All of our Japanese-English interpreters are of course well experienced with this quirk but don’t be surprised if the delay is slightly different one way, it is how they make sure their interpreting is the most faithful and accurate!
