Business Japanese Apology Phrases for Work

Business Japanese apology phrases should sound responsible, polite, and action-focused. The safest pattern is:

apology + problem + next action

For a general workplace apology, use 申し訳ございません (mōshiwake gozaimasen, I sincerely apologize), then state what happened, then explain what you will do next. This keeps your message respectful without sounding panicked or defensive.

For a broader cultural overview, read our guide to apologizing in Japanese business situations. This page focuses on ready-to-use phrases for emails, messages, meetings, customer replies, and serious mistakes.

Core Business Japanese Apology Phrases

Use 申し訳ございません (mōshiwake gozaimasen, I sincerely apologize) for clients, customers, managers, and formal email. Use 申し訳ありません (mōshiwake arimasen, I am sorry) for polite internal workplace situations.

The phrase alone is not enough. In business Japanese, a good apology usually tells the other person that you understand the inconvenience and that you are already taking action.

Choosing the Right Formality

Choose the phrase by seriousness, relationship, and medium. Written messages to customers need more formal language than a quick spoken apology to a close coworker.

ごめん (gomen, sorry) and ごめんなさい (gomennasai, I’m sorry) are common in daily life, but they are usually too casual or personal for work. They may be fine with a close coworker in a relaxed chat, but they are not safe for clients, customers, formal email, or serious mistakes.

For small interruptions, 失礼しました (shitsurei shimashita, excuse me / sorry) is useful. For example, use it when you enter a meeting late, interrupt someone, or correct a small attachment mistake.

For most professional apologies, 申し訳ありません (mōshiwake arimasen, I am sorry) is a strong internal default. For outside your company, senior people, or customer-facing communication, 申し訳ございません (mōshiwake gozaimasen, I sincerely apologize) is safer.

For official written apologies, お詫び申し上げます (owabi mōshiagemasu, I offer my sincere apology) sounds formal and serious. It is powerful, so do not use it for every small internal mistake.

If your workplace Japanese also includes greetings and first meetings, review how to introduce yourself politely in Japanese so your tone stays consistent before and after an apology.

Email and Message Templates

Start work emails with the apology, explain the issue briefly, then give the action and timing. Avoid long excuses before the apology.

Subject lines can stay simple in English if your workplace uses English, but in Japanese business email you may see patterns like “Apology regarding the delayed reply,” “Correction to the attached file,” or “Notice regarding the revised document.” Keep the subject factual, not emotional.

Use these templates as models:

Late reply

返信が遅くなり、申し訳ございません。すぐに内容を確認いたします。
Henshin ga osoku nari, mōshiwake gozaimasen. Sugu ni naiyō o kakunin itashimasu.
I apologize for the late reply. I will check the details immediately.

Missed deadline

提出が遅れ、申し訳ありません。本日中にお送りします。
Teishutsu ga okure, mōshiwake arimasen. Honjitsuchū ni o-okuri shimasu.
I am sorry the submission is late. I will send it by the end of today.

Wrong attachment

添付ファイルに誤りがありました。失礼しました。正しいファイルを再送いたします。
Tenpu fairu ni ayamari ga arimashita. Shitsurei shimashita. Tadashii fairu o saisō itashimasu.
There was a mistake in the attached file. Sorry about that. I will resend the correct file.

Incorrect information

先ほどの内容に誤りがありました。確認不足で申し訳ございません。訂正版をお送りします。
Sakihodo no naiyō ni ayamari ga arimashita. Kakunin fusoku de mōshiwake gozaimasen. Teiseiban o o-okuri shimasu.
There was an error in my earlier message. I sincerely apologize for not checking carefully. I will send the corrected version.

For an email closing, add one clear next step rather than repeating apologies many times. A sentence like “I will check again and contact you by the end of today” is usually better than three different apology phrases.

Customer Support and Serious Mistakes

For customers, lead with inconvenience, use formal language, and say what will happen next. This is safer than explaining the internal reason too early.

A customer-support reply often follows this shape:

1. Acknowledge the inconvenience.
2. Apologize formally.
3. State that you will check the cause.
4. Give the next contact or correction.

Example:

ご不便をおかけし、誠に申し訳ございません。原因を確認し、改めてご連絡いたします。
Gofuben o okake shi, makoto ni mōshiwake gozaimasen. Gen’in o kakunin shi, aratamete go-renraku itashimasu.
We sincerely apologize for the inconvenience. We will check the cause and contact you again.

For a serious mistake involving another company, use the company name clearly: ABC株式会社 (ABC kabushiki-gaisha, ABC Corporation). Avoid vague blame. You can write that your side is checking the cause, preparing a correction, or escalating internally.

In Japanese, over-explaining can sound defensive, especially before the apology. English speakers often want to give context first: “Because the system was down…” In business Japanese, it is usually better to apologize first, then give only the necessary explanation.

Pronunciation and Tone Tips

Say apology phrases slowly, evenly, and clearly. A rushed apology can sound casual even if the words are polite.

Long vowels matter. In 申し訳ございません (mōshiwake gozaimasen, I sincerely apologize), mō is long. In お詫び申し上げます (owabi mōshiagemasu, I offer my sincere apology), mō is also long. In お送りします (o-okuri shimasu, I will send), pronounce the honorific お (o) before the verb clearly.

Do not make your voice overly dramatic. A calm, lower tone sounds more professional than a very emotional apology. In meetings, pause briefly after the apology, then move to the action: what you will check, send, correct, or confirm.

Common Mistakes and Practice

Learners often apologize too casually, explain too much, or forget the action step. Fix those three points and your business Japanese will immediately sound more professional.

Common learner errors:

• Incorrect/Common learner error: using ごめんなさい (gomennasai, I’m sorry) in a formal customer email.
• Better: use 申し訳ございません (mōshiwake gozaimasen, I sincerely apologize).
• Incorrect/Common learner error: explaining the reason first and apologizing later.
• Better: apologize first, then give the shortest useful explanation.
• Incorrect/Common learner error: ending with only “sorry.”
• Better: add an action such as checking again, sending a correction, or contacting the person later.

Practice building one complete apology:

申し訳ございません。確認不足でした。すぐに修正いたします。
Mōshiwake gozaimasen. Kakunin fusoku deshita. Sugu ni shūsei itashimasu.
I sincerely apologize. I did not check carefully enough. I will correct it immediately.

Now replace the final action:

1. 再度確認いたします。
   Saido kakunin itashimasu.
   I will check again.
2. 本日中にご連絡いたします。
   Honjitsuchū ni go-renraku itashimasu.
   I will contact you by the end of today.
3. 正しい資料をお送りします。
   Tadashii shiryō o o-okuri shimasu.
   I will send the correct materials.

Answers: all three are correct formal action phrases. Choose the one that matches the actual next step.

FAQ

Is 申し訳ございません more polite than 申し訳ありません?

Yes. 申し訳ございません (mōshiwake gozaimasen, I sincerely apologize) is more formal than 申し訳ありません (mōshiwake arimasen, I am sorry). Use the first for customers, clients, senior people, and serious email. Use the second for many internal workplace apologies where you still need professional tone.

Is ごめんなさい acceptable at work?

ごめんなさい (gomennasai, I’m sorry) is understandable, but it is usually not safe for business Japanese. It can sound personal, casual, or childish in formal settings. Use it only with close coworkers in relaxed situations. For email, customers, managers, or mistakes with impact, choose a formal apology phrase.

What is the difference between お詫び申し上げます and 謝罪いたします?

お詫び申し上げます (owabi mōshiagemasu, I offer my sincere apology) is a very formal written apology and often sounds customer-facing. 謝罪いたします (shazai itashimasu, I apologize) is direct and formal, but can sound more official or procedural. For learners, お詫び申し上げます is usually safer in formal apology notices.

Should I use すみません in business email?

すみません (sumimasen, sorry / excuse me) is fine for light spoken situations, but it is often too casual for business email. If the message involves a delay, error, client, customer, or senior person, use 申し訳ありません (mōshiwake arimasen, I am sorry) or 申し訳ございません (mōshiwake gozaimasen, I sincerely apologize) instead.
