Ohayou vs Ohhah – How Japanese Greetings Get Funky

Overview

SummaryIn Japanese, “Ohayou” (おはよう) is a casual and friendly way to say “Good morning.” But if you’ve watched Japanese variety shows, especially Oha-Suta or seen Shingo Mama in action, you might have heard the exaggerated, playful version: Ohhah!
This funky twist on a simple greeting became a pop culture catchphrase, blending real-life language with TV humor. Let’s explore how a basic greeting turned into a comedy goldmine.
