How to Say Thank You and Sorry in Japanese: A Situational Guide
Arigatō and sumimasen are only starting points. Natural Japanese thanks and apologies name the relationship, the size of the favor or mistake, and whether you are speaking before or after it.
How to Say Thank You and Sorry in Japanese: A Situational Guide
Japanese has several ways to express gratitude and apology because social meaning matters as much as dictionary meaning. Sumimasen can apologise, get attention, or even thank someone for taking trouble. Arigatō changes formality through gozaimasu and gozaimashita. At work, mōshiwake arimasen and osewa ni natte orimasu carry meanings that a direct translation misses. This guide maps the most useful expressions to real situations and shows the follow-up sentence that makes each one sound sincere.
Use arigatō gozaimasu as the safe polite default for gratitude
Use sumimasen for a small apology, attention, or gratitude for inconvenience
Match apology strength to the consequence, not only to your emotion
Add what you appreciate or how you will fix the problem to sound sincere
The safest thank-you phrases
Japanese
Romaji
Meaning
ありがとう。
Arigatō.
Thanks. (casual)
ありがとうございます。
Arigatō gozaimasu.
Thank you. (polite, present or ongoing)
ありがとうございました。
Arigatō gozaimashita.
Thank you. (for something completed)
どうもありがとうございます。
Dōmo arigatō gozaimasu.
Thank you very much.
本当にありがとう。
Hontō ni arigatō.
Thank you, truly. (personal/casual)
Gozaimasu makes the expression polite; dōmo adds emphasis. The past form gozaimashita often follows a completed service, visit, lesson, or event. Japanese speakers do not enforce a mechanical present-versus-past rule in every exchange, so focus on whether you are thanking someone during an ongoing interaction or looking back as it closes.
Say what you appreciate
Japanese
Romaji
Meaning
手伝ってくれてありがとう。
Tetsudatte kurete arigatō.
Thanks for helping me. (casual)
教えていただき、ありがとうございます。
Oshiete itadaki, arigatō gozaimasu.
Thank you for explaining/telling me.
お時間をいただき、ありがとうございます。
Ojikan o itadaki, arigatō gozaimasu.
Thank you for your time.
助かりました。
Tasukarimashita.
That really helped me.
おかげさまで。
Okagesama de.
Thanks to you / thanks to everyone's support.
A specific thank-you feels stronger than adding more intensifiers. The casual pattern te-form + kurete arigatō thanks someone for an action. The polite pattern te-form + itadaki, arigatō gozaimasu frames the action as something you humbly received. Tasukarimashita is a warm, useful follow-up after practical help.
Everyday ways to say sorry or excuse me
Japanese
Romaji
Meaning
ごめん。
Gomen.
Sorry. (casual)
ごめんなさい。
Gomen nasai.
I'm sorry. (everyday)
すみません。
Sumimasen.
Excuse me / I'm sorry / thank you for the trouble.
失礼しました。
Shitsurei shimashita.
Excuse my rudeness / I beg your pardon.
お待たせしました。
Omatase shimashita.
Sorry to have kept you waiting.
Use sumimasen to call a server, pass through a crowd, ask a question, or apologise for a small inconvenience. Gomen is personal and casual. Shitsurei shimashita acknowledges a lapse in manners, such as interrupting or using the wrong name. Omatase shimashita is a fixed, listener-focused apology that names the exact burden.
Formal and workplace apologies
Japanese
Romaji
Meaning
申し訳ありません。
Mōshiwake arimasen.
I sincerely apologise.
大変申し訳ございません。
Taihen mōshiwake gozaimasen.
I am deeply sorry. (very formal)
ご迷惑をおかけしました。
Gomeiwaku o okake shimashita.
I caused you inconvenience.
確認不足でした。
Kakunin busoku deshita.
My checking was insufficient.
今後このようなことがないようにいたします。
Kongo kono yō na koto ga nai yō ni itashimasu.
I will ensure this does not happen again.
A strong business apology normally has three parts: acknowledgement, responsibility, and action. Say what happened without hiding behind a vague phrase, explain the immediate remedy, and state how recurrence will be prevented. Excessively formal words without a concrete repair can sound less sincere than a clear moderate apology.

How to respond to thanks and apologies
Japanese
Romaji
Meaning
どういたしまして。
Dō itashimashite.
You're welcome.
いえいえ。
Ie ie.
Not at all. (friendly)
こちらこそ。
Kochira koso.
Likewise / I should thank you.
大丈夫です。
Daijōbu desu.
It's okay.
気にしないでください。
Ki ni shinaide kudasai.
Please don't worry about it.
Dō itashimashite is correct but can sound more formal or textbook-like than a modest ie ie or kochira koso. Daijōbu desu works for a small inconvenience, but do not use it to erase a real workplace consequence. A practical response such as 'I received the corrected file' may be more appropriate.
Common mistakes and a practice method
Using casual arigatō with a customer, senior colleague, or new acquaintance.
Choosing gomen nasai for a serious professional error because it feels emotionally sincere.
Repeating sumimasen many times without naming the problem or solution.
Translating dō itashimashite into every reply instead of using a modest response.
Forgetting that tone, timing, facial expression, and a bow also communicate seriousness.
Key points
A practical way to improve
Roleplay four scenes: a friend gives you a gift, a stranger helps with directions, you arrive ten minutes late, and you send a wrong file at work. Choose a different expression for each, then add one sentence naming the favor or your corrective action.
1
Choose one clear goal
Focus each session on a situation or skill you can actually use.
2
Practice actively
Say complete answers aloud instead of only reading or recognizing Japanese.
3
Review and repeat
Keep useful corrections and revisit the same skill until it feels natural.
FAQ
Frequently asked questions
What is the most polite way to say thank you in Japanese?
Dōmo arigatō gozaimasu is warmly polite in everyday situations. For a completed favor, arigatō gozaimashita is natural. Formal business gratitude often uses expressions such as makoto ni arigatō gozaimasu or a sentence naming the support received.
Why can sumimasen mean both sorry and thank you?
Sumimasen acknowledges that you imposed on someone. Depending on tone and context, that can be an apology, a request for attention, or gratitude for the trouble they took. English separates these functions more sharply than Japanese does.
Is gomen nasai rude?
Gomen nasai is a genuine everyday apology, suitable with family, friends, and many personal situations. It is not strong or formal enough for a serious workplace error, a customer complaint, or a major consequence.
How should I respond to an apology in Japanese?
For a small issue, daijōbu desu means it is okay, and ki ni shinaide kudasai means please do not worry about it. In business, acknowledge the explanation and move to the solution rather than automatically saying there was no problem.
