親しき仲にも礼儀あり
shitashiki naka ni mo reigi ari
Lent a book to a friend and never got it back? Japanese people would remind your friend: shitashiki naka ni mo reigi ari (親しき仲にも礼儀あり).
I’m Arasen, an elementary school principal and calligrapher in Japan. It’s one of the keys to understanding Japanese manners.
Quick Facts
| Japanese | 親しき仲にも礼儀あり |

| Reading | したしきなかにもれいぎあり |
| Romaji | shitashiki naka ni mo reigi ari |
| Literally | Even in a close relationship, there is courtesy |
| Meaning | Be polite even to people you’re close to. |
| English cousin | A hedge between keeps friendship green. |
What Does It Mean?
However close you are to someone, you must still keep good manners with them.
Word by Word
| 親しき仲 | shitashiki naka – a close relationship (shitashiki is old Japanese for shitashii, close) |
|---|---|
| にも | ni mo – even in |
| 礼儀 | reigi – courtesy, manners |

Where Does It Come From?
As people get closer, they stop holding back – and a little too much freedom can hurt the other person and break the friendship.
Sayings with the same wisdom exist around the world, like Germany’s “Love your neighbor, but don’t tear down the fence.”
A Word from Arasen
However close you are, there are manners you should keep.
When you’re good friends, you stop being careful and holding back. But if it goes too far, it can cause a fight.
This is advice from people long ago: treat each other with respect.
Do you skip greetings with your parents or friends, or use rough words with them? Let’s not break our relationships with the people who matter most.
Even with someone very close, a small kind gesture makes them happy, doesn’t it?
(Translated from Arasen’s original Japanese.)
