V ましょう

This expression is used when a speaker is positively inviting the listener to do something with the speaker. It is also used when responding positively to an invitation.

[Note] V ませんか and V ましょう are both used to invite someone to do something, but V ましょう shows that the speaker is giving more consideration to what the listener might want than V ましょう.

Example 1: ちょっと休みましょう。（ちょっとやすみましょう。） — Let's take a break.

Example 2: いっしょにごはんを食べませんか。（いっしょにごはんをたべませんか。） — Shall we have lunch together?

Example 3: ええ、食べましょう。（ええ、たべましょう。） — Yes, let's do that.
