How to Write a Polite Japanese Email: A Practical Guide A polite Japanese email opens with a greeting that matches the relationship, then the request, then a fixed sign-off. For an ongoing work contact, start with osewa ni natte orimasu. When you need them to respond, close with yoroshiku onegai itashimasu rather than a casual bye. Japanese email greeting お世話になっております (osewa ni natte orimasu) is the usual opener for an ongoing business contact. For a first email, 初めてご連絡いたします (hajimete go-renraku itashimasu) says this is the first time you are writing. Japanese email sign-off よろしくお願いいたします (yoroshiku onegai itashimasu) is the usual formal close when you are asking the reader to respond or to handle the request. Short sample お世話になっております。 株式会社 [company] の [name] と申します。 ご確認いただけますでしょうか。 よろしくお願いいたします。 Japanese business and formal emails follow a structure far more standardized than typical English correspondence. Skipping the expected conventions doesn't just look unusual — it can read as careless or even disrespectful in professional contexts. Here's a practical breakdown of how to structure one correctly, greeting to closing. How should I greet someone in a formal Japanese email? Unlike English, where "Hi" or "Dear" works broadly, Japanese formal emails open with a greeting tailored to the relationship and situation. お世話になっております (osewa ni natte orimasu, roughly "thank you for your continued support") is the standard opener for ongoing business relationships, while 初めてご連絡いたします (hajimete go-renraku itashimasu, "this is my first time contacting you") suits a first email to someone new. How do I introduce myself in a Japanese business email? Immediately after the greeting, state your name and affiliation clearly, especially in first-time correspondence: 株式会社〇〇の〇〇と申します (kabushikigaisha [company] no [name] to moushimasu, "I am [name] from [company]"). This isn't just politeness — it gives the recipient immediate context for who's writing and why, which matters more in Japanese business culture than many learners expect. How do I state my purpose without sounding blunt? Japanese business writing eases into the main point slightly more gradually than direct English correspondence, but excessive vagueness is equally unhelpful. A common, effective structure briefly references the context — a previous conversation, an attached document, a prior meeting — before clearly stating the specific request or information, avoiding both bluntness and unnecessary circling around the actual point. How do I use humble and honorific language correctly? Verbs describing your own actions typically use humble form (謙譲語), while verbs describing the recipient's actions use honorific form (尊敬語). For example, asking someone to check something uses ご確認いただけますでしょうか (go-kakunin itadakemasu deshou ka, "could you please check"), rather than a plain or casual request form. This distinction is one of the clearest signals of formal email competency that native readers notice immediately. If the honorific/humble split still feels shaky, formal vs. casual Japanese breaks down when to use each register. How should I close a formal Japanese email? Formal emails typically close with よろしくお願いいたします (yoroshiku onegai itashimasu), which has no clean single English translation but functions as a polite, all-purpose closing acknowledging the request or relationship. Skipping this closing phrase, even after an otherwise well-structured email, can make the message feel abruptly cut off to a native reader. What formatting conventions do Japanese business emails follow? Japanese business emails use line breaks more frequently than English correspondence, breaking up even moderately short paragraphs for visual clarity. Subject lines should be specific and concise, clearly indicating the email's purpose rather than a vague subject that requires opening the email to understand its relevance. These formatting habits, while seemingly minor, add to an overall impression of professionalism that…
Frequently asked questions
- Is it rude to use casual Japanese in a work email?
- Yes, in most cases. Even with colleagues you know well, business emails generally default to polite (teineigo) or honorific/humble register unless the relationship and company culture clearly allow otherwise.
- What's the minimum I need to know to write a passable business email?
- A relationship-appropriate greeting, a clear self-introduction on first contact, a request phrased with humble or honorific verb forms, and a standard closing phrase like よろしくお願いいたします cover most routine situations.
- Do I need different Japanese for internal vs. external emails?
- Often, yes. Internal emails to peers can use a moderately polite register, while external emails to clients or senior contacts usually call for fuller honorific and humble forms.
- How do I get better at this beyond reading guides?
- Read real sample business emails, notice how greetings, requests, and closings are phrased in different contexts, and draft your own for feedback from a teacher or native speaker. Exposure to real examples builds this skill faster than memorizing templates alone.
