The Safest Way To Say Good Morning

The standard polite phrase is おはようございます.
Ohayō gozaimasu
Meaning: Good morning

The casual version is おはよう.
Ohayō
Meaning: Morning / Good morning

Most of the time, Japanese writes these in hiragana. Rare kanji forms exist, but they are not the default in normal daily writing. So yes, the fancy kanji is real, but no, you do not need to march around using it like a linguistic peacock.

Pick The Right Version

A useful rule: if you would not call the person “dude,” do not open with the casual form on day one.

How To Pronounce It Without Sounding Like A Robot

• おはよう = o-ha-yō. Stretch the last ō a little.
• おはようございます = o-ha-yō go-za-i-ma-su. In natural speech, the final u in ます is often very light.
• Do not flatten it into “Ohio.” Japanese learners have all done this at least once. The language remembers.

Example:
おはようございます。今日は早いですね。
Ohayō gozaimasu. Kyō wa hayai desu ne.
Good morning. You’re early today.

When To Use It

Use おはようございます in the morning when you first greet someone in a polite setting. Use おはよう with people you know well. In many workplaces, especially shift-based jobs, おはようございます can also be used as the first greeting of your workday even if your shift starts later. That is why you may hear it in the afternoon or evening at work and think, “Morning? Sir, it is 5:12 p.m.” Japanese is not broken. The context changed.

Outside that kind of workplace context, switch later in the day to こんにちは (Konnichiwa, hello / good afternoon) and こんばんは (Konbanwa, good evening).

  Use おはようございます unless the relationship is clearly casual.
• Writing the rare kanji every time.
  Use hiragana in normal writing: おはよう and おはようございます.
• Thinking it only works before a strict clock time.
  In offices and shift jobs, it can mean “first greeting of the workday,” not only “the sky is still morning-colored.”
• Switching to こんにちは too early in a workplace where everyone says おはようございます.
  Mirror the house style when you are new.
• Pronouncing it too flat.
