Translation guide
The English word "nightcap" has two main meanings: a drink before bed and a soft hat worn in bed. This guide covers both, with a focus on natural Japanese expressions.
To refer to an alcoholic drink taken just before going to sleep, often to help one relax or sleep.
To refer to a soft, often pointed cap worn in bed, historically or in stories.
In Japanese, ナイトキャップ only refers to the hat. For the drink, use 寝酒 or a descriptive phrase. Using ナイトキャップ for the drink will cause confusion.
I had a glass of whiskey as a nightcap.
A less common but poetic synonym for 寝酒. Literally 'sleep sake'.
眠り酒にブランデーを少しだけ。
Just a little brandy as a nightcap.
A descriptive phrase meaning 'a drink before bed'. More casual and conversational.

A nightcap is my daily routine.
In Japanese, there is no direct loanword for 'nightcap' in the drink sense. Avoid literal translations like ナイトキャップ, which would be misunderstood as the hat.
