Invitations: 〜ませんか and 〜ましょう
Invite someone versus proposing a shared action.
In short
Verb ませんか is a common polite invitation: 一緒に食べませんか, “Would you like to eat together?” 〜ましょう is a proposal: 食べましょう, “Let’s eat.”
How it works
ませんか leaves more room for the other person to accept or decline. ましょう sounds more like moving forward with a shared plan.
Useful contrast
Casual conversation uses plain alternatives such as 行かない？ and 行こう.
Examples
映画を見ませんか。
Would you like to see a film?
そろそろ行きましょう。
Let’s get going soon.
Common pitfall
For someone you do not know well, a question-style invitation can feel easier to decline than a strong proposal.
