oyasumi

Oyasumi is a Japanese phrase used to bid someone goodnight. It is a shortened form of the more formal expression "oyasumi nasai." The word "oyasumi" itself is derived from the verb "yasumu," which means "to rest" or "to sleep." The prefix "o-" is an honorific that adds politeness to the expression. Therefore, "oyasumi" literally translates to "please rest" or "please sleep."

The phrase is commonly used in informal settings among family, friends, and close acquaintances. When used with strangers or in more formal situations, "oyasumi nasai" is generally preferred. It is typically spoken before going to bed or when parting ways with someone late in the evening.

The cultural significance of "oyasumi" lies in its role as a polite and caring closing to the day. It conveys a wish for a peaceful and restful sleep. Like "goodnight" in English, it is a customary expression that marks the transition from waking hours to sleep. The use of "oyasumi" reflects the Japanese emphasis on politeness and consideration for others in everyday interactions.
