Good Morning
expression
From Ohio (おはよう), you shout good morning. Why Ohio? Because that's where you woke up this morning. Imagine yourself waking up in Ohio, and wishing everyone "good morning" at the top of your lungs. おはよう is a casual way to say "good morning." It can also be written in kanji, but hiragana is much more common.
ミホちゃん、おはよう！
Good morning, Miho-chan!
マイクに「おはよう」とメールをした。
I texted "good morning" to Mike.
うーっ、ねむいー、おはよう。
Ugh, I'm sleepy... morning.
