Japanese business email follows formulas. Once you know the formulas, translating an English email becomes a structural problem — not a creative writing problem. This guide shows the five-block structure of every Japanese business email, the phrases each block uses, and how to use a Japanese business email translator to assemble them correctly.
The five-block structure
- Greeting + self-introduction (one line)
- Context / setup (one to two lines)
- The request or content (two to five lines)
- Closing courtesy (one line)
- Sign-off (one line)
Almost every business email — internal or external, short or long — fits this. Generic translators don't enforce the structure; business email translators do.
Block 1 — Greeting + self-introduction
For known contacts: いつもお世話になっております。BizHonyakuの田中です。
For first contact: 初めてご連絡させていただきます、BizHonyaku株式会社の田中と申します。
For internal: お疲れさまです。営業部の田中です。
Block 2 — Context / setup
Tell the reader why this email exists before what you want. English often gets straight to the ask; Japanese business norms expect a beat of setup first.
- 先日ご相談させていただいた件について、続報をお送りいたします。
- 本日は◯◯の件でご連絡いたしました。
- 貴社のホームページを拝見し、ぜひ一度お話を伺わせていただきたく、ご連絡申し上げます。
Block 3 — The request
Wrap the actual ask in cushion phrases and humble verbs. Direct imperatives ("please send X") read as cold or hostile in Japanese business context.
English source: Please send the updated quote by Friday.
Generic translation: 金曜日までに更新された見積もりを送ってください。
Business email translation:
お忙しいところ恐縮ですが、金曜日までに更新版の見積書をお送りいただけますと幸いです。
Block 4 — Closing courtesy
The standard set:
- 引き続きどうぞよろしくお願いいたします。
- ご検討のほど、何卒よろしくお願い申し上げます。
- お返事をお待ちしております。
Block 5 — Sign-off
Standard format:
----- 田中 太郎 BizHonyaku 株式会社 営業部 Email: tanaka@bizhonyaku.com Tel: 03-1234-5678
What a Japanese business email translator does that Google doesn't
- Picks the right opening based on whether the recipient is known or new
- Inserts the right cushion phrase in front of any request
- Closes with the right courtesy line based on context (negotiating, post-contract, apology)
- Catches double-honorifics like ご確認頂戴いたします
- Preserves your terminology across emails — your company name, your titles, your products — via a glossary
Practical workflow
- Draft the email in English
- Translate with a Japanese business email translator (recipient + relationship settings)
- Read the output once — does the register feel right for the relationship?
- For high-stakes emails (apologies, executive contact), have a native bilingual reader pass it
- Send
BizHonyaku is built around this workflow. The dropdown settings for recipient and relationship are the difference between a polite Japanese email and a socially-correct one. Try it free for five emails per month — no signup required for the first translation.
