How do you say "Do I need to come again?" in Japanese?

Quick use

Use またこなければなりませんか (mata konakereba narimasen ka) when you want to know whether you must come back another day.

It is useful before leaving the office.

Chunk or pattern

This is best learned as one practical question.

It is a little longer, but very useful because it checks whether today’s visit is enough.

Core words

• また: again.
• こなければなりませんか: do I have to come?

Helper words and endings

なりませんか appears here as part of a “do I have to ...?” question.

You do not need a full grammar lesson at first. Learn the whole line as “Do I need to come again?”

Practical note

Use this before you leave the counter. If the answer is yes, you can follow up with いつまでですか (itsu made desu ka) or なにをもってくればいいですか (nani o motte kureba ii desu ka).
