Is 'Ohayo' Really Casual? the Linguistic Truth and Media Mythology Explained
By Maya Lin-Takahashi
Q1: Can I say "Konnichiwa" in the morning if I forget "Ohayo gozaimasu"?
A1: Saying *konnichiwa* before 10:30 AM sounds awkward to native speakers because *konnichiwa* inherently carries midday associations. If you forget *ohayo gozaimasu* in an office setting, a crisp *otsukaresama desu* or a respectful bow paired with *shitsurei shimasu* is far more natural than defaulting to *konnichiwa*.
Q2: Why do martial artists and athletes shorten the greeting to "Osu"?
A2: The exclamation *osu* (often romanized as *ossu*) is an aggressive abbreviation of *o-hayō gozaimasu*, popularized during the mid-20th century in collegiate budo clubs, military academies, and karate dojos. It conveys grit, endurance, and camaraderie, but using it in conventional corporate offices or toward strangers comes across as abrasive or unrefined.
Q3: Is it rude to answer an elder or boss with just "Ohayo"?
A3: Yes. Dropping *gozaimasu* when speaking to superiors, senior colleagues (*senpai*), teachers, or strangers is a serious breach of etiquette. The single word *ohayo* should only be used when speaking laterally to classmates, downward to younger siblings, or casually to close friends and immediate family.
