How to Say Thank You in Japanese — 6 Ways, Casual to Formal
ありがとうございます is thank you in Japanese — until the favor ends and it becomes ございました. When to use each, how to reply, and where すみません fits.
Present and past: Japanese conjugates its thanks
The first hurdle is tense. For a kindness happening now you say ありがとうございます; for one that has finished you say ありがとうございました. That is why restaurant staff thank you in the past form as you leave — the service is complete.
Getting it wrong will not break communication, but using the present form after the fact leaves a faint sense that you think the interaction is still ongoing. A simple rule: once the lesson has ended, the gift is in your hands, or the help is finished, switch to ございました.
| Japanese | Reading | When to use it |
|---|---|---|
| ありがとうございます | arigatou gozaimasu | The default — a kindness happening now |
| ありがとうございました | arigatou gozaimashita | For something already completed |
| ありがとう | arigatou | Casual — friends and family |
| どうも | doumo | Light thanks — taking a bag from a shop clerk |
| どうもありがとうございます | doumo arigatou gozaimasu | Emphatic — "thank you very much" |
| 恐れ入ります | osore irimasu | Highly formal — business and hospitality |
Why すみません often means thank you
Japanese frequently uses the apology すみません (sumimasen) where English would use thank you. The focus shifts to the trouble the other person went to on your behalf, so the feeling sits between gratitude and apology. Someone picking up something you dropped is the classic case.
A workable rule: if the other person spent time or effort, すみません fits; if you simply received a gift or goodwill, ありがとうございます is right. Stringing them together — すみません、ありがとうございます — is completely natural too.
How to reply to thanks
どういたしまして (dou itashimashite) is what textbooks teach and it is not wrong, but it sounds stiff in casual conversation. Native speakers reach far more often for light deflections like いえいえ or とんでもないです.
| Japanese | Reading | Feel |
|---|---|---|
| いえいえ | ie ie | "No no, it's nothing" — the everyday default |
| とんでもないです | tondemonai desu | A polite, self-lowering "not at all" |
| こちらこそ | kochira koso | "It is I who should thank you" |
| どういたしまして | dou itashimashite | The textbook answer — a little stiff in practice |
Sorry and I love you in Japanese
After thanks, the phrases learners look up most are apologies and declarations of affection. Apologies split by register between すみません and ごめんなさい: and with affection, the word to be careful with is 愛してる (aishiteru), which is far heavier than its English translation.
| Japanese | Reading | Meaning and use |
|---|---|---|
| すみません | sumimasen | "Excuse me" / "sorry" — the all-purpose one |
| ごめんなさい | gomen nasai | A personal apology — casual form ごめん |
| 申し訳ありません | moushiwake arimasen | Formal apology — business settings |
| 好きです | suki desu | "I like you" — the usual way to confess feelings |
| 大好き | daisuki | "I really like/love it" — warm and widely used |
| 愛してる | aishiteru | "I love you" — weighty and rarely said aloud |
Even between partners, 愛してる is said sparingly in Japan; confessions and everyday affection usually go through 好きです or 大好き instead. Copying a drama line directly can land far heavier than the moment calls for.

The lesson has just ended and you thank your teacher. Which form fits?
Learning these with the situation attached
For courtesy phrases, the hard part is not the meaning but which form belongs to which moment. Rehearsing them attached to concrete scenes — paying, finishing a lesson, being offered a seat — is what makes them arrive on time in real conversation.
When the tense or the nuance is unclear, default to ありがとうございます. Missing the past form is a small thing; skipping the thanks altogether is what actually stands out.
Frequently asked questions
How do you say thank you in Japanese?
Say ありがとうございます (arigatou gozaimasu). With friends use plain ありがとう, and どうも for a light thanks. If the favor is already finished, use the past form ありがとうございました.
What is the difference between ございます and ございました?
It is a tense distinction. Use ございます for a kindness in progress and ございました once it is complete — after a lesson ends or a meal is finished, the past form is the natural choice.
Do Japanese people actually say 愛してる?
It is correct but rarely spoken. The phrase carries a lot of weight, so confessions and everyday affection usually use 好きです (suki desu) or 大好き (daisuki) instead.
