Formal Expressions: Polite Language
When speaking in formal situations or with people you are not familiar with, it’s important to use polite language in Japanese. Here are some phrases to express the idea of “need to do something” formally:
- ～しなければなりません (〜しなければなりません)
This expression is one of the most common ways to say “need to do something” in a polite manner. To use it, simply combine the appropriate verb form with “しなければなりません.” It expresses a necessary obligation or requirement.
Example:
宿題 (しゅくだい) を やらなければなりません。
(I need to do my homework.)
明日 (あした) は 早 (はや) く 起 (お) きなければなりません。
(I must wake up early tomorrow.)
～なければいけません (〜なければいけません)
This expression has a similar meaning to the previous one but is used interchangeably. Replace “なりません” with “いけません” to express the need to do something politely.
Example:
日本語 (にほんご) を もっと 勉強 (べんきょう) しなければいけません。
(I need to study Japanese more.)
申 (もう) し 訳 (わけ) ありませんが、もう 一度 (いちど) 試験 (しけん) を 受 (う) けなければいけません。
(I’m sorry, but I have to take the test again.)
Informal Expressions: Casual Language
When speaking in informal situations or with close friends and family, it’s common to use casual language. Here are some expressions for expressing the concept of “need to do something” informally:
- ～ないと (〜ないと)
This expression is a casual way to express the notion of “need to do something.” Simply remove “なければ” from the formal expressions and add “と” after the verb stem.
Example:
宿題 (しゅくだい) を やらないと。
(I need to do my homework.)
明日 (あした) は 早 (はや) く 起 (お) きないと。
(I must wake up early tomorrow.)
～なくちゃ (〜なくちゃ)
This expression is very similar to the previous one and is also commonly used in casual conversations. Replace “ないと” with “なくちゃ” to convey the sense of “need to do something.”
Example:
日本語 (にほんご) を もっと 勉強 (べんきょう) しなくちゃ。
(I need to study Japanese more.)
申 (もう) し 訳 (わけ) ないけど、もう 一度 (いちど) 試験 (しけん) を 受 (う) けなくちゃ。
(I’m sorry, but I have to take the test again.)

Japanese has different levels of politeness, and it’s essential to use the appropriate expressions based on the formality of the situation.

(Please practice more.)
