Good Night

Japanese

おやすみなさい

Oyasuminasai

Lesson & Usage

[English equivalent: "Good night."] Use this phrase before going to sleep or when leaving someone's house late at night. It is a polite way to end the day. Between close friends or family members, you can shorten it to "Oyasumi."

This comes from the verb "Yasumu" (休む), which means to rest. By saying "Oyasumi-nasai," you are essentially saying "Please have a good rest." The "nasai" part at the end actually comes from a polite command, showing that the speaker is looking out for the other person’s well-being and encouraging them to recover their energy for the next day.
