How to Say “I Will Be Late” in Japanese

遅刻します
Chikoku shimasu
In Japanese, "I will be late" is expressed as 遅刻します (Chikoku shimasu).
This phrase is used to inform someone that you will not arrive at a scheduled time, such as an appointment, school or work.

What does it mean word for word?

The expression is composed of the noun 遅刻 (chikoku), meaning tardiness or being late and the verb します (shimasu), which means "to do". When combined, they form the phrase "to be late".

Which one should you use?

While 遅刻します is a standard polite way to announce tardiness, you may also encounter 遅れます, which is a common and polite alternative. For casual settings, 遅れるよ provides a friendly tone, while the dictionary form 遅刻する is used for informal situations with friends or family.

Is there a formal and an informal way to say it?

The form 遅刻します is polite and suitable for use with teachers, bosses or acquaintances. For more casual interactions with friends or family, you should use the informal 遅刻する or the friendly 遅れるよ.

Did you know?

  • When reporting that they will be late to a boss, Japanese employees often use the phrase 申し訳ございません (moushiwake gozaimasen), meaning 'there is no excuse', as a mandatory preface to 遅刻します.
  • The kanji 刻 in 遅刻 means 'time' or 'carving', referring to the precise carving of marks on a sundial or water clock to track time.
  • In Japanese culture, the concept of 'punctuality' is so high that arriving exactly at the scheduled time can sometimes be viewed as being 'on the edge'. To be truly safe and polite, one often aims to arrive several minutes early.
