How to Say Good Night in Japanese – Oyasumi (おやすみ) & More

The Japanese language offers speakers a diverse vocabulary to be used in casual and format situations respectively. This includes saying good morning or good night in Japanese to your friends, coworkers, or boss. This article will help you understand how to say good night and good morning in Japanese using a variety of phrases including the most commonly used, おやすみ (oyasumi), which simply translates to “goodnight” (casual) and おやすみなさい (oyasuminasai) which also means goodnight but this is a formal form..  

おやすみ (oyasumi) in a Break Down

Beginning with the common way to say good night in Japanese, おやすみ (oyasumi), it’s important to understand that it actually originates from the Japanese verb “ yasumu (休む)” which has multiple meanings. Some of the meanings include: to be absent, to take a day off, to rest, to have a break, to go to bed, or to rest” As you can see there are many scenarios in which the verb can be used, however, it’s important to remember the context of the situation first, whether casual or formal.

Additionally, two important conjugations can be added in order to make the phrase more polite when used in a sentence. These conjugations are なさい (Nasai) – Do and てください (Te kudasai) – Please.  When adding “nasai” it would become “oyasuminasai”, this makes the word more formal and polite and perfect for work environments or when dealing with authority figures. てください (Te kudasai) – Please, is a suffix added when using “oyasuminasai” in order to make a polite request.

  • おやすみなさい。またあした
    • (oyasuminasai. mata ashita)
      • Good night. See you tomorrow.

Perfect for use when saying goodbye or goodnight to colleagues at the end of a work day.

  • お会いできて良かったです、おやすみなさい
    • (O ai dekite yokattadesu, oyasuminasai )
      • It was good to see you, goodnight

This is a great option to use when leaving the company of a friend.

When Can We Use おやすみ (oyasumi) ?

Seeing as Oyasumi can be used in so many different scenarios it’s important to understand how to actually use it best when the time comes. Below we will provide a detailed breakdown of the various situations in which it can be used and how best to apply it.

1. When You Are Going To Bed

This is a perfect time to use Oyasumi as it will serve to politely excuse yourself from the conversation if you have been speaking to a friend or a relative. If it’s late at night, even better! As you can let the person know that you’ll be going to bed soon or are tired and will be departing from their company or the conversation.

  • そろそろ寝(ね)るね、おやすみ
    • (sorosoro nerune, oyasumi)
      • I’m about to sleep, goodnight.

2. When You Leave Late At Night

When you and a friend or co-worker have been out socializing and it’s time to leave and go home perhaps one of them is about to catch the train or call a cab. This would be the perfect time to use oyasumi and it can be adjusted easily in terms of the formality of the situation. If you’re out with a colleague that perhaps you aren’t that close with it’s always best to oyasuminasai.

  • 私は今出発しなければなりません、おやすみなさい私は明日あなたに会います
    • (Watashi wa ima shuppatsu shinakereba narimasen, oyasuminasai watashi wa ashita anata ni aimasu)
