Today’s Case

レジぶくろは ごいりよう ですか?
Do you need a plastic bag?

大丈夫 です
Daijoubu desu.

Does this customer need a plastic bag or not?
Which is it?
Decoder’s Notes
This is a conversation you’ll often hear at convenience stores and supermarkets in Japan.
When the clerk asks, “Would you like a plastic bag?”, the customer replies, “Daijoubu desu.” So, does this customer want a plastic bag or not? What do you think?
The word daijoubu literally means “it’s okay” or “there’s no problem.”
However, in this situation, “Daijoubu desu” actually means:
“No, I don’t need a plastic bag.”
Thus, the meaning of daijoubu changes depending on the situation.
When someone is checking whether something is needed or not, “Daijoubu desu” usually means:
“I don’t need it.” / “No, thank you.”
The Clue
Sometimes, instead of saying “No” directly, Japanese people use “Daijoubu desu.”
This is often a way of being polite and considerate.
In many situations, Japanese speakers prefer a softer expression like “Daijoubu desu” rather than giving a direct “No.”

That said, don’t worry too much about saying the “perfect” thing.
Even if you simply say “Iranai desu” (directly saying “I don’t need it.”), most Japanese people won’t think you’re being rude.
If “Daijoubu desu” doesn’t come to mind, just politely say “Iranai desu.” That’s fine!
There are many different ways to say “I don’t need a plastic bag” in Japanese.
One of the interesting things about Japanese is that there often isn’t just one correct answer. The expression people choose depends on the situation, the relationship, and even personal speaking style.
That’s what makes observing real Japanese so much fun!
Today’s Field Mission

Next time you’re at a convenience store or supermarket in Japan, listen for someone saying “Daijoubu desu.”
Did it mean “I don’t need it”?
Also, see if you can spot any other expressions people use instead of “Daijoubu desu.”
The more you observe, the more Japanese you’ll discover!
If you get the chance, try using “Daijoubu desu” instead of saying “No.”
Did the clerk understand you naturally?

See you in the next case!
