How to Respond to "Thank You" in Japanese: Formal and Casual Ways to Say "You're Welcome"
Learn when to use どういたしまして, いいえ, 大丈夫です and other natural replies to thanks in formal and casual Japanese, with pronunciation and example dialogue.
By LiamCulture & nuance · Yapr Learn
When someone thanks you in Japanese, the reply you choose depends on how close you are to the person and how formal the situation is. A phrase that sounds perfectly polite to a coworker can sound stiff between friends, and a casual reply can seem careless to a customer or a teacher. This lesson focuses only on responding to thanks. You will learn five common replies, the difference between formal and informal use, and how to avoid the most frequent mistake learners make. All examples use natural Japanese script with Hepburn romanization so you can read and say them right away.
By the end, you can…
- respond to thanks politely in a formal situation using どういたしまして.
- choose a casual reply such as いいよ or 全然大丈夫 for friends.
- distinguish when いいえ sounds natural and when it can confuse the listener.
Listen once. Try it slowly. Then say it without looking.

どういたしまして。
You're welcome.
do itashimashite
The standard polite reply. Safe with teachers, coworkers, customers and strangers. In very casual chat it can sound slightly formal or textbook-like, so friends often prefer something lighter.
いいえ、とんでもないです。
No, not at all. / It was nothing.
iie, tondemonai desu
A humble, polite response used when someone thanks you for a favor or compliment. The いいえ softens the thanks, and とんでもないです makes the reply modest. Common in business and service situations.
いいよ、気にしないで。
It's fine, don't worry about it.
ii yo, ki ni shinaide
Casual and friendly. Use with close friends, family or people your own age. 気にしないで literally means "don't mind it" and works like "no worries."
全然大丈夫ですよ。
It's totally fine. / No problem at all.
zenzen daijōbu desu yo
A natural, friendly reply that is polite enough for most everyday situations. 全然 (zenzen) means "totally" here, and 大丈夫 (daijōbu) means "fine" or "all right." The final よ softens the tone.
またいつでも言ってください。
Please ask me anytime.
mata itsudemo itte kudasai
A warm, helpful reply when you have done someone a favor. It shifts the focus to future help and sounds considerate in both casual-polite and business settings. また means "again" and いつでも means "anytime."
Pronunciation guides are approximate. Slow playback keeps the original pitch.
Make it make sense
Useful pattern
Many replies to thanks in Japanese begin with a short softening word, then add a short comment. A common pattern is いいえ + a modest phrase, as in いいえ、とんでもないです (iie, tondemonai desu). Another pattern is 大丈夫です + よ, as in 全然大丈夫ですよ (zenzen daijōbu desu yo). The final particle よ adds a reassuring tone, like "really, it's fine." If you want to offer future help, use またいつでも言ってください (mata itsudemo itte kudasai). Notice that Japanese replies often avoid a direct "you're welcome" and instead reduce the size of the favor or reassure the person.
When to use it
Use どういたしまして (dō itashimashite) in formal situations: with a teacher, a manager, a customer or someone you have just met. Use いいえ、とんでもないです (iie, tondemonai desu) when you want to sound humble, especially after a compliment or a thank-you for a small favor. With friends, いいよ、気にしないで (ii yo, ki ni shinaide) or 全然大丈夫ですよ (zenzen daijōbu desu yo) sound natural and warm. If you are not sure about the level of formality, 全然大丈夫ですよ is a safe middle choice in daily life, while どういたしまして remains the safest choice in business or service settings.
Listen to each line, then take one part and reply out loud.
手伝ってくれて、ありがとうございます。
Thank you for helping me.tetsudatte kurete, arigatō gozaimasuいいえ、とんでもないです。
No, not at all.iie, tondemonai desu本当に助かりました。
It really helped me.hontō ni tasukarimashitaまたいつでも言ってください。
Please ask me anytime.mata itsudemo itte kudasaiA little context goes a long way
Japanese replies to thanks often downplay the favor rather than accept praise directly. Saying いいえ does not mean you are rejecting the thanks; it is a polite way to be modest. In business, a humble phrase such as とんでもないです is usually safer than a casual いいよ, even if your coworker is friendly. When in doubt, match the other person's politeness level.
One thing to watch for
Using どういたしまして with close friends in a very casual chat, because it is the first phrase in many textbooks.
Try this instead: どういたしまして is correct and polite, but it can sound stiff between close friends. In casual talk, use いいよ、気にしないで (ii yo, ki ni shinaide) or 全然大丈夫だよ (zenzen daijōbu da yo). Keep どういたしまして for teachers, coworkers, customers and strangers.
Your turn
Try answering out loud before checking a possible answer.
1A coworker says ありがとうございます after you send a document. Which reply is the safest polite choice?
Show a sample answer
どういたしまして。
どういたしまして is the standard polite reply and fits a workplace situation with a coworker. いいえ、とんでもないです is also acceptable and sounds humble, but どういたしまして is the most neutral safe choice.
2Your close friend says ありがとう after you lend them a pen. Which casual reply fits best?
Show a sample answer
いいよ、気にしないで。
いいよ、気にしないで is casual and friendly, matching a close friend. 全然大丈夫だよ would also work. どういたしまして would be too formal for this situation.
3Someone thanks you for a small favor, and you want to offer help again in the future. What can you say?
Show a sample answer
またいつでも言ってください。
またいつでも言ってください means "Please ask me anytime" and politely invites future requests. It works in both polite and business settings. A more casual version would be またいつでも言ってね.
Match your reply to the situation: use どういたしまして or とんでもないです in formal settings, and いいよ、気にしないで or 全然大丈夫 for friends. When unsure, choose the polite form.
