Study the materials below, then start.

1. Introduction / はじめに

Writing a work email in English feels scary for many Japanese learners. You might worry: "Will I sound rude?" or "Is my English good enough?" The answer is yes — your English is good enough. Most polite work emails use the same simple patterns every time. You only need four things: a clear subject line, a polite greeting, a short and clear message, and a simple closing.

When do you use work emails? / どんな場面で使う?

  • Scheduling a meeting — 会議の日程確認・変更・キャンセル(confirming, changing, or cancelling a meeting time)
  • Requesting a document or file — 書類・ファイルの送付依頼(asking a colleague or client to send something)
  • Giving a status update — プロジェクトの進捗報告(telling your team about project progress)
  • Asking a question — 同僚や上司への質問(checking a detail with a coworker or manager)
  • Following up — 返信がないときの再連絡(checking in after no reply)
  • Apologising or explaining a delay — 遅れや不都合のお詫び(letting someone know something is late)
  • Thanking someone professionally — ビジネス上のお礼(acknowledging someone's help)

2. Core Language Pattern / 基本のパターン

Almost every polite work email follows this three-part template. Learn this, and you can write most work emails.

📧 The Three-Part Email Template / 3パーツのテンプレート
Part 1 — Opening: "I hope you are doing well. I am writing to [reason]."
Part 2 — Main point: "Could you please [action]?" or "I would like to [action]."

5. Naturalness Tips / 自然に聞こえるコツ

  • Tip 1: Don't just answer — add one more line.
    Adding one follow-up line shows you are helpful and thinking about the other person. / 一言付け加えるだけで、相手を思いやる丁寧な印象になります。
    ❌ "The meeting is on Monday."
    ✅ "The meeting is on Monday at 10:00 a.m. Please let me know if this time works for you."
  • Tip 2: Use "I am writing to..." to get to the point fast.
    One sentence is enough. "I am writing to..." signals your reason immediately. / 一文で十分。「I am writing to...」で用件をすぐに伝えられます。
    ❌ "Hello. I have something to ask you. I was thinking about the meeting. I want to change it."
    ✅ "I am writing to ask if we could reschedule Tuesday's meeting."
  • Tip 3: Soften requests with "when you have a moment" or "if possible."
    "If possible" makes a request sound less like a demand. / 「If possible」を加えるだけで、お願いの雰囲気になります。
    ❌ "Send me the file by tomorrow."
    ✅ "Could you please send me the file by tomorrow if possible?"
  • Tip 4: Use "Thank you for your understanding" after inconvenient news.
    Acknowledging the other person's inconvenience sounds professional and considerate. / 相手への影響を認めると、プロらしく思いやりのある印象になります。
    ❌ "I cannot attend the meeting. Sorry."
    ✅ "I am afraid I cannot attend the meeting on Thursday. I apologise for the inconvenience, and thank you for your understanding."
  • Tip 5: Extend a short answer by offering next steps.
    Telling people "what comes next" saves them from having to ask. / 次のステップを伝えると、相手が確認する手間を省けます。
    ❌ "I finished the report."
    ✅ "I have finished the report. I will send it to you this afternoon. Please let me know if you need any changes."

6. Common Mistakes to Avoid / やってはいけないこと

❌ Mistake 1: Using command form for requests

英語では命令形でお願いすると失礼に聞こえます。「Could you please...?」を使いましょう。

❌ Wrong: "Send me the document."
✅ Correct: "Could you please send me the document?"
❌ Mistake 2: Writing a subject line that is too vague

件名が曖昧だとメールが見落とされます。用件を具体的に1行で書きましょう。

❌ Wrong: Subject: "Hi" / Subject: "Question"
✅ Correct: Subject: "Question about Friday's meeting" / Subject: "Request for sales report"
❌ Mistake 3: Skipping the greeting or closing

あいさつも締めの言葉もないメールは冷たく失礼な印象になります。必ず両方入れましょう。

❌ Wrong: (Starting directly with) "I need the file by Friday."
✅ Correct: "Hello Ken, I hope you are doing well. Could you please send me the file by Friday?"
❌ Mistake 4: Writing one giant paragraph

長い段落は読みにくいです。1段落に1つの内容を書き、段落の間には空白行を入れましょう。

❌ Wrong: (One long paragraph with no spacing or structure)
✅ Correct: Use short paragraphs — one idea per paragraph. Leave a blank line between them.
❌ Mistake 5: Forgetting to mention the attachment

添付ファイルがある場合は、本文でも必ず一言触れましょう。「Please find the attached file.」が定番です。

❌ Wrong: (Attaching the file but not mentioning it in the email body)
✅ Correct: "Please find the report attached." or "I have attached the file for your reference."
❌ Mistake 6: Being too apologetic

謝りすぎると不自然です。英語では簡潔な一言のお詫びで十分です。日本語のような深いお詫びをそのまま英語にすると、大げさに聞こえます。

❌ Wrong: "I am so very sorry to bother you. I apologise deeply for asking. I feel terrible for taking your time."
✅ Correct: "I apologise for the short notice." or "Sorry for the inconvenience."
