How to Say “‘must'” in Japanese

なければならない
nakereba naranai
The Japanese phrase for 'must' is なければならない (nakereba naranai).
This phrase is used to express a strong necessity or a requirement to do something. It often carries a nuance of an objective requirement or a social obligation rather than a personal desire.

What does it mean word for word?

The phrase is literally composed of a conditional 'if not' (nakereba) and a verb meaning 'it will not do' or 'it is no good' (naranai), translating to 'if [one] does not [do it], it will not do'.

Which one should you use?

While なければならない expresses a strong necessity, it often carries a nuance of an objective requirement or a social obligation rather than a personal desire.

Is it said differently in some regions?

In the Kansai region, including cities like Osaka and Kyoto, the expression なあかん is mainly used.

How does it change in a sentence?

In casual speech, the long phrase 'nakereba naranai' is often shortened to なきゃ.

How do you pronounce it?

nakereba naranai

Did you know?

  • Japanese speakers often avoid using なければならない in direct conversation because it can sound overly demanding or bossy, opting instead for softer expressions that suggest a need rather than a command.
  • The second half of the phrase, ならない, is a negative form of the verb 'naru' (to become). It effectively communicates that the state of 'not doing' is a state that 'cannot become' or is unacceptable.
  • The phrase なきゃ is so common in casual speech that it is often used as a standalone exclamation when someone suddenly remembers a task they forgot to do.
