まじか

• Reading: まじか
• Romaji: majika
• Pronunciation: /ma.dʑi.ka/

Meaning

An expression of disbelief meaning 'for real?' or 'seriously?' — one of the most common reactions in texting.

まじか is the casual question form of マジ (maji, seriously). It is the texting equivalent of 'are you serious?' or 'no way.' In hiragana, it feels softer and more natural in text than the katakana マジか. It works as a standalone reaction to surprising, shocking, or unbelievable news — both positive and negative. One of the most frequently sent single-word messages in Japanese texting, alongside え and うそ.

Examples

1. まじか、あの店閉まったの？ For real, that place closed down?
2. 彼氏できた？まじか！おめでとう！ You got a boyfriend? Seriously!? Congrats!
3. まじか…それはきついな。 For real… that's rough.
