Translating Business Emails

A grammatically correct translation of a business email can still land badly. Japanese and English business writing follow different conventions for length, directness, and structure, and a literal translation carries the wrong convention into the wrong language.

Japanese business emails open differently

A typical Japanese business email opens with a seasonal greeting or a set phrase like お世話になっております (osewa ni natte orimasu, roughly "thank you for your continued support"), even in a first contact email. Translated literally into English, this reads as oddly formal or even confusing, since English business email tends to open directly with the subject at hand.

Directness levels differ

English business writing, especially American English, tends to state the request early and directly. Japanese business writing often builds context first and states the actual ask later, sometimes softened with conditional phrasing. A literal translation can make a Japanese email sound vague to an English reader, or make an English email sound abrupt to a Japanese reader.

Closings carry different weight

よろしくお願いいたします (yoroshiku onegai itashimasu) appears at the end of nearly every Japanese business email and doesn't have a single fixed English translation. Depending on context it functions like "thank you in advance," "best regards," or simply a polite sign-off with no direct content. Translating it the same way every time often produces a stiff or repetitive-sounding email.

A practical checklist before sending a translated business email

• Check the opening. If translating from Japanese, consider dropping or shortening the standard greeting phrase for an English audience.
• Check directness. If translating into English, make sure the actual request appears early, not buried after several sentences of context.
• Check the closing. Don't translate よろしくお願いします the same way every time; match it to what the sentence is actually doing.
• Check formality consistency. Japanese keigo levels don't map onto a single English register, so read the whole translated email and make sure the tone feels consistent throughout, not formal in one paragraph and casual in the next.
• Read it out loud. A simple way to catch awkward phrasing that grammar-checking alone misses.
