くさいものにふたをする
kusai mono ni futa o suru
A test with a terrible score, pushed to the back of a drawer… Japanese people call that kusai mono ni futa o suru (くさいものにふたをする).
I’m Arasen, an elementary school principal and calligrapher in Japan. It’s the Japanese version of “sweeping it under the rug” – but much smellier!

What Does It Mean?
To hide something bad that you don’t want others to know about – just to get through the moment, without really fixing it.
It is also used when people look away from things they don’t want to see.
Word by Word
| くさいもの | kusai mono – something that smells bad |
|---|---|
| にふたをする | ni futa o suru – to put a lid on |
Where Does It Come From?
If you put a lid on something smelly, the smell goes away – for a while. But the cause is still there.
A Word from Arasen
When you do something wrong or make a mistake, and it would be inconvenient for others to find out, you try to hide it just for now. That’s what this proverb means. We also use it when we look away from things we don’t want to see.
Even with a lid on, if the source of the smell is still there, it’s only a temporary fix. Take the lid off, and it still stinks. In fact, it might smell twice as bad!
Hiding what you couldn’t do makes it invisible – but only for a while. That’s the advice from people long ago.
(Translated from Arasen’s original Japanese.)

勇輔!!見せなさい。何!!テストじゃないの!!!15点!!!勇輔、くさいものに蓋をするのはやめなさい!!Mom, I’m sorry!
