“Excuse me / Sorry!” -> すみません (Sumimasen)
“I sincerely apologize.” -> 申し訳ありません (Moushiwake arimasen)
Apologizing correctly is a crucial skill in Japanese society. While すみません is incredibly versatile for daily life, using it when you make a mistake at work can make you sound insincere. Let’s master the art of the Japanese apology with Joy and Ken!

🗣 Conversation Scene

Joy is writing an email to a client after sending a document late.

Joy
ケンさん、お客様（きゃくさま）にメールを書きました！
「書類（しょるい）が遅（おく）れて すみません」でいいですか？
(Ken, I wrote an email to the client! Is “Sumimasen for the late document” okay?)
Ken
Joyさん、お客様に対して「すみません」は少し軽（かる）いです。
ビジネスの謝罪（しゃざい）には「申（もう）し訳（わけ）ありません」を使いましょう！
(Joy, toward a client, “Sumimasen” is a bit light. For business apologies, let’s use “Moushiwake arimasen”!)

💡 Explanation

Everyday Versatility vs. Formal Apology

1. すみません (Sumimasen) = Sorry / Excuse me

Level: Polite but Light 💧
This is an incredibly versatile word. It can mean “Sorry” (for a small mistake), “Excuse me” (to get attention), or even “Thank you” (for someone’s minor trouble). However, because it has so many meanings, it lacks the weight needed for a serious apology.

  • [Excuse me] すみません、注文（ちゅうもん）をお願いします。
    (Excuse me, I’d like to order.)
  • [Light Sorry] 足を踏（ふ）んでしまって すみません。
    (Sorry for stepping on your foot.)

2. 申し訳ありません (Moushiwake arimasen) = I sincerely apologize

Level: Highly Formal / Business 🙇‍♀️
Literally translates to “I have no excuse.” This is strictly used for apologizing. It shows deep regret and professionalism. You use this with clients, bosses, or when you have caused a significant problem.

  • [Business] ご迷惑（めいわく）をおかけし、申し訳ありません。
    (I sincerely apologize for the inconvenience caused.)
  • [Formal] 遅刻（ちこく）してしまい、申し訳ありませんでした。
    (I am deeply sorry for being late. *To a boss*)
