A classic Japanese phrase! 😊

"うにゅう、おはようさん" is a playful way to say "Good morning, teacher!" or more formally, "Honorable teacher, good morning".

The phrase is composed of:

* うにゅう (o-yasumi nasai) - a polite way to say "good morning"
* おはよう (ohayou) - a casual way to say "good morning"
* さん (san) - a honorific suffix used when addressing someone with respect, in this case, the teacher.

So, if you're looking for a fun and respectful way to greet your Japanese teacher or educator, this phrase is perfect! 😊
