Translation guide
The English phrase 'one more' is used to request an additional item, repeat an action, or indicate a single extra thing. In Japanese, the expression depends on what you are counting or requesting. The most common equivalent is もう一つ (mō hitotsu) for generic objects, but counters and context-specific phrases are often more natural.
You want one more of something, like a drink, a piece of food, or an object, without specifying the type.
The most versatile way to say 'one more' for objects. Uses the generic counter つ. Suitable for many everyday items.
One more, please.
Would you like one more?
Emphasizes 'one more remaining' or 'one more to go'. Often used when counting down or finishing a set.
One more and it's done.
You want one more of something that requires a specific counter, like flat objects, cylindrical objects, or people.
Replace [counter] with the appropriate counter word. For example, 一枚 (いちまい) for flat objects, 一本 (いっぽん) for long objects, 一人 (ひとり) for people.
One more (flat object) please.
One more beer, please.
One more person is coming.
Similar to もう, but emphasizes 'one more remaining'. Use with counters.
I can eat one more (small round thing).
You want to do something again, or ask someone to repeat an action.
You want to express that there is an extra item or person beyond what was expected.
Do not translate 'one more' word-for-word as 一もっと (ichi motto) or 一以上 (ichi ijō). These are not natural Japanese for this meaning.
Japanese uses specific counters for different types of objects. If you know the counter, use it with もう or あと for more natural speech. If unsure, もう一つ is a safe fallback for many physical objects.
