Ajasu Meaning: Korean Internet Slang for ‘Thanks’
아자스 (ajasu) is a casual ‘thanks’ clipped from Japanese ありがとうございます. Learn its meme tone, where Koreans use it, and when 감사합니다 is safer.
아자스 (ajasu) means a casual “thanks.” It is clipped from Japanese ありがとうございます and reused in Korean internet speech with a light, sometimes joking tone. With staff, clients, or strangers, use 감사합니다 instead.
Not 아자아자
Learners mix it with fighting cheers. Wrong tree. This one is gratitude — light, clipped, often half-joking.
공유해 줘서 아자스.
Thanks for sharing.
Reason + thanks wants -아서/어서: 도와줘서… — same rule as 고마워 / 죄송합니다.
Who says it to whom
Friend / comment section: fine if that circle already says it.
Customer → staff: no. Use 해요체 / 합니다체 감사합니다.
Learner trying to sound Japanese-cool in Seoul: easy to misfire. Many adults will just blink.
When the word itself is the topic:
아자스가 뭐야? — What is ajasu?
이/가 introduces the unknown label.
When not to use it
- Job interviews, emails, elders, client calls.
- As your only thank-you strategy.
- Quoting hostile meme variants you do not understand — some online spins are ironic or community-specific.
Learner move
Recognise it in slang lists next to 야르. Produce 고마워 / 감사합니다 until a friend uses 아자스 first.
Common questions
Is it the same as 파이팅 / 아자아자?
No. That sound-alike confusion is common. 아자스 is thanks, not a cheer.
Can it be sarcastic?
Online, yes — tone and context can flip a thank-you into irony. Offline with strangers, assume confusion, not sarcasm.
Should learners say it in Japan?
Use full ありがとうございます with people you do not know. The clip is casual even there.
Where will I see it?
Comments, creator speech, Gen Z slang roundups — often listed beside 야르 and friends.
