Why Politeness and Social Context Matter in Japan
Choose an expression for the relationship and the task. A familiar form can fit an established casual relationship; a polite form is a useful starting point when you are unsure. Listen to complete exchanges rather than treating each phrase as a word-for-word replacement.
Casual Ways to Say “Thank You” in Japanese
When speaking with friends, siblings, or others you’re close with, a laid-back tone works just fine. Casual expressions for “thank you” are straightforward and commonly heard in daily life. They’re quick to say and easy to remember, making them ideal for everyday use without the need for added formality.
1. ありがとう (Arigatou) – “Thank you”
Pronunciation: ah-ree-gah-toh
“Arigatou” is probably the most common way to say “thank you” in Japanese when you’re talking to someone you know well. It’s casual, easy to say, and you’ll hear it all the time between friends, family, or classmates. Imagine your friend helps you carry your groceries—just a simple “Arigatou!” is all it takes to show you appreciate it.
2. どうも (Doumo) – “Thanks”
Pronunciation: doh-moh
“Doumo” is a super casual way to say thanks—short and easy. People often use it in quick situations where a full “thank you” might feel a bit too much. Like when someone holds the door open for you, a simple “Doumo!” is more than enough.
3. サンキュー (Sankyu) – “Thank you”
Pronunciation: san-kyuu
“Sankyu” is a phrase borrowed from English that has been adapted into Japanese. It’s considered very casual and is commonly used among younger people or in informal settings. For example, after receiving a small favour from a friend, one might say, “Sankyu!”

The full phrase is a polite closing used in business emails and formal letters when requesting cooperation or consideration. It is not a direct expression of gratitude but a formal request that carries an implicit sense of appreciation. You will frequently see it at the end of proposals, business correspondence, and formal requests.
Apologies and thanks: related uses, different meanings
すみません can express thanks when someone has taken trouble on your behalf, as the Japan Foundation explains. The longer formal expressions below are apologies, however; do not treat every apology as another literal way to say thank you.
17. すみません (Sumimasen) – “Excuse me / Thank you for the trouble”
Pronunciation: soo-mee-mah-sen
Though commonly known as “excuse me” or “sorry,” it’s also used to express gratitude, especially when someone has gone out of their way. For instance, if someone waits for you when you’re late, saying “Sumimasen” is a way to express both apology and thanks.
18. 申し訳ありません (Moushiwake arimasen) – “I sincerely apologise”
Pronunciation: moh-shee-wah-keh ah-ree-mah-sen
This is a formal apology, not a literal translation of thank you. If you also want to thank someone for help, choose a separate expression of gratitude that fits the situation.
19. ご迷惑をおかけして申し訳ありません (Gomeiwaku o okake shite moushiwake arimasen) – “I apologise for the inconvenience”
Pronunciation: goh-may-wah-koo oh oh-kah-keh shee-teh moh-shee-wah-keh ah-ree-mah-sen
This sentence apologises for causing inconvenience. It does not literally say thank you for your patience. Keep the apology and any separate thanks distinct when choosing what to write.
More Expressions Related to “Thank You”
These less common expressions are context-dependent and often reflect deeper emotion or formality.
20. 助かります (Tasukarimasu) – “That really helps, thank you”
Pronunciation: tah-skah-ree-mas
Used when someone’s help makes a difference. It’s less about the favour itself and more about the outcome. For instance, if someone brings you medicine when you’re sick, “Tasukarimasu” reflects relief and gratitude.
21. 恩に着ます (On ni kimasu) – “I’m deeply indebted to you”
Pronunciation: ohn nee kee-mas
A very humble phrase expressing a sense of moral indebtedness. It’s rarely used in daily conversation but may appear in historical dramas or formal writing.
22. ありがたく存じます (Arigataku zonjimasu) – “I am grateful” (very formal)
Pronunciation: ah-ree-gah-tah-koo zon-jee-mas
This is a deeply formal version of “thank you,” commonly used in corporate speeches or formal writing. It expresses not just thanks but also solemn appreciation.
Gestures and regional expressions
This guide focuses on expressions you can practise in complete exchanges. If you are studying a regional variety or a particular formal occasion, check its wording and etiquette with an appropriate local resource or teacher rather than assuming a regional expression or a memorised bow angle fits every situation.

Practise choosing an expression
These are illustrative learning situations, not quotations from a class. More than one expression may fit. The answers below show possible choices and explain the intended distinction.
- A shop assistant has just helped you find an item. Give a simple polite thank you.
One possible answer: ありがとうございます. The help has just happened, but that does not make this form inappropriate.
- You are finishing a polite exchange after someone helped you with a report.
One possible answer: ありがとうございました. It can mark thanks at the close of the exchange; it is not the only wording possible for every colleague.
- You want to make a formal request for cooperation at the end of a business email.
何卒よろしくお願いいたします is a request closing. It is related courtesy language, not a literal translation of thank you.
- A friend lends you a book, and you normally use casual speech together.
ありがとう is a possible familiar thank you. The stated relationship matters; a person being younger alone is not the exercise’s deciding rule.
