The Japanese phrase Ki o tsukete means "take care." It is the phrase you would use when saying goodbye to a friend (whom you expect to see again within a few days) or a boss or coworker (whom you expect to see the next day or after a weekend). But the phrase deserves some explanation.

Many in Western cultures believe that the Japanese use sayounara when saying goodbye. Nothing could be further from the truth, notes FluentU, adding that not only is this stereotyping, but the term sayonara also implies a finality, as if you are saying goodbye for good. "Saying sayounara to a boss or loved one may leave them feeling confused or upset," says the language website.

If you plan to study Japanese or visit Japan, it's important that you know how to say goodbye in a socially appropriate way. Read on to learn how to use the phrase Ki o tsukete, including how to pronounce it and in what social context to use it.

"It is a phrase which signifies that one is praying for the safe trip of another. As such, it is a phrase that only the person watching someone else go is able to use. The person leaving cannot say it to the person staying behind."

In other words, only the person staying behind can use the phrase to, essentially, wish a safe journey to the person who is leaving. So, if you are the one leaving work or home, FluentU suggests the following alternative phrases for saying goodbye in Japanese:

  • 行って来ます (いってきます, itte kimasu) > I’m leaving home
