Writing Business Emails to Japanese Clients: Tips for English Speakers
Japan has long been a major player in global business, and for many professionals, working with Japanese clients and colleagues is simply part of the job. But while English is widely used in international business, how you write your emails still matters, especially when your reader comes from a business culture with very different communication norms.
This post covers what English speakers should keep in mind when writing business emails to Japanese recipients.
Japanese business culture values consideration over directness
In English, a well-written business email is typically direct, concise, and clearly structured around the main point. That style works well in English-speaking contexts, but it can read as abrupt or even cold to a Japanese reader.
Japanese business communication places a strong emphasis on consideration for the other person. This shows up in several ways: softening requests before making them, acknowledging the reader’s time and effort, and generally taking a less transactional tone. A straightforward request that sounds perfectly professional in English can come across as blunt in Japanese. Not because the words are wrong, but because the framing is.
This doesn’t mean you need to rewrite your emails from scratch. But being aware of this difference will help you strike a warmer tone, even in English.
Lead with the relationship, not the request
One of the most noticeable structural differences between English and Japanese business emails is where the main point goes.
English emails tend to be conclusion-first: state the purpose upfront, then provide context. Japanese business emails typically work the other way. They open with a greeting that acknowledges the ongoing relationship, move through some context or background, and arrive at the request toward the end.
When writing in English to a Japanese reader, you don’t need to adopt the full Japanese structure. But leading with a brief relationship acknowledgment before getting to the point will land much better than jumping straight into the request. This might feel slightly more formal than your usual American email style, but it signals that you recognize the relationship, not just the transaction. Something as simple as “Thank you for your continued support” or “I hope our collaboration has been going well” before the main point can make a real difference.
Soften requests more than you normally would
In Japanese business culture, making a request without softening it first is considered inconsiderate. Expressions like “I’m sorry to trouble you, but...” or “I apologize for the inconvenience, but...” are standard practice in Japanese business communication. They are not signs of weakness or over-apologizing. They are expected.
When writing in English to a Japanese counterpart, adding a brief softening phrase before a request goes a long way. Compare:
“Please review the attached document by Friday.”
versus
“I apologize for the short notice. Would you be able to review the attached document by Friday?”
To an English speaker, both are polite. To a Japanese reader, the second version shows consideration and is much more likely to be well received.
Formality is the safer default
When in doubt, err on the side of being more formal rather than less. Japanese business culture tends toward formality, especially with external contacts or new relationships. An email that’s slightly more formal than necessary is easy to forgive; one that comes across as too casual can leave a lasting impression.
A quick note on AI tools: if you use something like ChatGPT to look up a Japanese phrase or expression to include in your email, keep in mind that tone doesn’t always carry over accurately. A phrase that reads as warm and professional in English can come across as stiff or unnatural in Japanese. If you’re unsure, check with someone who knows the language before sending.
Summary
Writing effectively to Japanese clients and colleagues comes down to a few adjustments: lead with the relationship before the request, soften requests more than you would in an English-speaking context, and default to formality when you’re unsure. These small shifts can make a meaningful difference in how your emails are received.
