How to Say ‘If you don't mind, could I buy you a drink?’ in Japanese

もしよかったら、一杯ご馳走させてもらえませんか。

moshi yokatsu tara ichi pai go chisou sa se te morae mase n ka

[moh-shee yokat tah-rah eechi pie goh CHEE-soh sah seh te moh-rah-eh mah-seh n ka]

💬 Usage Tip: させてもらえませんか literally means "won't you let me…?" It frames treating someone as a favour you're asking of them. Swap the action: 手伝わせてもらえませんか "could you let me help?"

🇯🇵 In Japan: Asking permission like this is respectful, not stiff. It gives the other person an easy way to decline without anyone losing face.
