Have you ever spotted a friend in the distance and waved?
Or called out to someone before they walked away?
A warm and familiar way to do that in Japanese is:
“Ōi!” (おーい)
Let’s hear how it sounds!
What is “Ōi!” (おーい)?
“Ōi!” is used to:
- Call someone’s attention
- Greet a friend from a distance
- Get a person’s attention in a casual way
It’s a friendly everyday expression heard all over Japan.
Pronunciation
ohhh-ee!
(Stretch the first sound as if your voice is traveling through the air.)

What Does “Ōi!” Look Like?
It looks like someone waving across a park.
A child calling for a parent.
A friend trying to catch someone’s attention.
How Do You Say It?
Say it loudly and cheerfully:
Ōoooi!
Like sending your voice to someone far away.
Example in Daily Life
Example: Calling to a friend
He spotted his friend across the street and waved —
Ōoooi!
The friend turned around with a smile.
Cultural Note
“Ōi!” is a fun example of what we call an Almost Onomatopoeia.
It doesn’t imitate a sound or movement like a typical Japanese onomatopoeia.
Instead, it is a natural human call that carries the same playful sound symbolism found throughout Japanese.
It suggests:
Friendliness
Calling out
Everyday communication
Compared with similar expressions:
- Wai! → a happy cheer
- Ōi! → calling to someone
- Oi Oi → expressing surprise or mild disbelief
Watch & Feel the “Ōi!” World!
Feel the “Ōi!” — Calling out
Try Using It!
When you spot a friend in the distance…
When someone is walking away…
When you simply want to get someone’s attention…
Call out naturally:
Ōoooi!
Sometimes a friendly voice can travel farther than you think.
