Masen Ka: Invite Someone to Do Something

A polite negative question can function as an invitation: 一緒に食べませんか. The speaker is proposing an activity, not merely stating that it will not happen. Context distinguishes an invitation from a literal question about whether someone does not do something.

Formation and use

Start from the polite negative and add か: 行きませんか, 見ませんか, しませんか. 一緒に often helps signal that the proposed activity is shared.

A natural acceptance is いいですね、行きましょう. A refusal can explain a scheduling problem: すみません、明日はちょっと…. Do not mechanically answer every invitation with はい、行きません.

Comparisons and common errors

ますか commonly asks about plans or habits, while ませんか can invite in the right context. The negative form does not by itself determine the social purpose; read the situation.

ましょう proposes doing something together more directly. ましょうか can offer help. For an invitation, use a suitable activity and time rather than translating every English “would you” as ませんか.
