一回 — Meaning, Readings & Examples

Noun, Adverb

Once" / "One Time

Counts a single occurrence, repetition, or round of an action.

Good to know

一回（いっかい） means once or one time.

Use it to count one round, one turn, one attempt, or one repetition. It feels practical and countable, like one try in a game, one rep in exercise, or asking someone to repeat something.

A very useful phrase is もう一回（もういっかい）, meaning one more time. Add お願いします（おねがいします） to make a polite request: もう一回お願いします（もういっかいおねがいします）, one more time, please.

一回（いっかい） and 一度（いちど） can both mean once, but they are not always interchangeable.

一回 is best for a single countable action or attempt. 一度（いちど） is more about one occasion or one experience, especially when saying you have done something at least once in your life.

Example

日本に一回行ったことがあります。

I have been to Japan once.
