How to say “Thank you” in Japanese
How to say thank you in Japanese: ありがとうございます (polite) vs ありがとう (casual), when each one fits, native audio for both, and an AI grader that scores you saying it.
ありがとうございます。
Thank you.
ありがとう。
Thank you.
When to use which
The two forms you need are ありがとうございます (arigatou gozaimasu) and ありがとう (arigatou). The long form is the safe default: shop staff, coworkers, teachers, strangers, anyone older than you. The short form is for friends, family, and people clearly junior to you. If you only memorize one, memorize the long one — a too-polite thank you is charming, a too-casual one can land as flippant.
The mistake English speakers make is treating ありがとう as the "normal" word because it's shorter and appears first in phrasebooks. In practice, Japanese adults say ありがとうございます far more often in a normal day — every konbini visit, every train station interaction, every email sign-off. ありがとう alone to a store clerk isn't offensive, but it marks you as either very casual or unaware of the register.
To add weight, put どうも in front: どうもありがとうございます is "thank you very much." You'll also hear どうも by itself as a light, almost throwaway thanks — fine for small favors, too light for real gratitude.

Frequently asked
What's the difference between ありがとう and ありがとうございます?
Register. ありがとうございます is the polite form for strangers, staff, coworkers, and anyone above you; ありがとう is the casual form for friends and family. The meaning is identical — the relationship it signals is not.
Is it rude to just say ありがとう?
To a friend, no — it's the natural choice. To a store clerk, your boss, or someone you just met, it reads overly familiar. When in doubt, use ありがとうございます; excess politeness is never held against a learner.
How do you say thank you very much in Japanese?
どうもありがとうございます (doumo arigatou gozaimasu). Adding どうも strengthens the thanks. Casually, どうもありがとう works the same way with friends.
