Saying "thank you" is one of the first things people learn in any language, and in Japanese, there are multiple ways to express gratitude. Whether you’re thanking a friend for a favor, showing appreciation in a formal setting, or responding politely to a customer, choosing the right phrase is essential.

In this guide, we’ll break down the different ways to say “thank you” in Japanese, when to use each, and how to avoid common mistakes.

Understanding the Levels of Politeness in Japanese Gratitude

Unlike English, where a simple "thank you" works in almost any situation, Japanese has different phrases depending on the level of formality and the relationship between the speaker and listener. The wrong choice might make you sound too casual or overly formal, so let’s explore the key expressions.

Polite Level 1

🤝 Domo (どうも) – A Quick, Casual Thanks

"Domo" by itself is a very short and informal way to say thanks. While it's not rude, it’s very casual and can feel abrupt.

• Best used for: Quick interactions, very casual settings.

• Example: A friend passes you your phone. You can say, Domo!

🚨 Be careful: Avoid using just “domo” in formal situations.

Polite Level 2

🙌 Arigato (ありがとう) – The Casual “Thanks”

If you’re speaking with close friends, family, or someone of equal status, "arigato" is a friendly and natural way to say thanks.

• Best used for: Friends, family, casual conversations.

• Example: Your friend lends you a pen. You can simply say, Arigato!

🚨 Be careful: Saying just “arigato” to a superior, teacher, or stranger may sound too informal.

🌟 Domo Arigato (どうもありがとう) – Emphasizing Your Gratitude

If you want to express a little extra appreciation but still keep it casual, you can say Domo arigato.

• Best used for: Showing stronger gratitude among friends.

• Example: Your coworker helps you finish a big project. You say, Domo arigato!

Polite Level 3

🙏 Arigato Gozaimasu (ありがとうございます) – The Polite “Thank You”

This is the safest and most commonly used way to say thank you in polite situations. Adding gozaimasu makes the phrase more respectful and suitable for workplace interactions, customer service, and speaking to strangers.

• Best used for: Work environments, customer interactions, teachers, strangers.

• Example: A store clerk helps you find an item, and you reply with, Arigato gozaimasu!

💡 Tip: When in doubt, use arigato gozaimasu. It’s always polite and appropriate.

🎓 Arigato Gozaimashita (ありがとうございました) – Thanking for Something in the Past

This variation is used when expressing gratitude for something that has already happened or been completed.

• Best used for: Thanking teachers after a lesson, acknowledging past favors.

• Example: After finishing a meal at a restaurant, you might say, Arigato gozaimashita to the staff.

Polite Level 4

🎩 Domo Arigato Gozaimasu (どうもありがとうございます) – A Very Polite and Grateful Thank You

For the most polite and heartfelt expression of gratitude, Domo arigato gozaimasu is the way to go. It emphasizes deep appreciation.

• Best used for: Formal settings, showing deep gratitude.

• Example: A boss gives you a great work opportunity, and you say, Domo arigato gozaimasu!

💡 Tip: This is a great phrase to use when expressing gratitude in business or formal events.

🧐 What About Sumimasen (すみません)? Can It Mean "Thank You"?

You might know sumimasen as a way to say sorry, but did you know it can also mean "thank you"? It's often used when someone goes out of their way to help you, kind of like saying, "Oh, I appreciate that!" The level of politeness can change depending on how sincerely or expressively you say it.

• Example: If someone holds a door open for you, you can say Sumimasen! to acknowledge their effort.

Common Mistakes to Avoid When Saying "Thank You" in Japanese

🚫 Using "Arigato" in Formal Situations – Always add gozaimasu for politeness.
🚫 Mixing Up Tenses – Use gozaimashita only when referring to something in the past.
🚫 Relying Too Much on "Domo" – It can sound abrupt if used alone in polite interactions.
