Ohayō, Konnichiwa, Konbanwa: Japanese Greetings by Time

Japanese beginner lessons often map three greetings neatly onto the day:

• おはようございます — ohayō gozaimasu: good morning
• こんにちは — konnichiwa: good afternoon / hello
• こんばんは — konbanwa: good evening

That map is useful. Real interaction adds relationship, workplace habits, and whether the meeting is the first one that day.

The short answer

Use ohayō gozaimasu in the morning and when beginning a work period where that greeting is customary. Use konnichiwa through much of the daytime, especially outside close family. Use konbanwa when meeting someone in the evening.

There is no national minute when every speaker changes greetings. Follow the light, setting, and people around you.

Ohayō and ohayō gozaimasu

Ohayō is casual. Ohayō gozaimasu is polite:

おはよう。 Ohayō. “Morning.”

おはようございます。 Ohayō gozaimasu. “Good morning.”

In some workplaces—especially shifts, entertainment, hospitality, and settings where people begin at different hours—ohayō gozaimasu can greet colleagues at the start of work even later in the day. This is a professional convention, not proof that the word has stopped meaning “morning.”

Konnichiwa

Konnichiwa is a daytime greeting for people you encounter rather than a phrase repeated throughout an ongoing conversation.

It is less common inside a household between family members who already share the day. There, people use situational language: ohayō, tadaima, or simply begin speaking.

The final sound is written は, not わ: こんにちは. In this expression, は reflects its historical grammatical role but is pronounced wa.

Konbanwa

Konbanwa is used when meeting someone in the evening:

こんばんは。 Konbanwa. “Good evening.”

Like konnichiwa, it is written with final は. It opens an encounter; it is not normally the phrase used when leaving for bed. For that, おやすみなさい — oyasuminasai means “good night.”

First meeting versus daily greeting

When meeting someone for the first time, a time-of-day greeting can precede an introduction, but it does not replace the introduction itself:

はじめまして。リーです。よろしくお願いします。 Hajimemashite. Rī desu. Yoroshiku onegaishimasu. “Nice to meet you. I’m Lee. I look forward to working with you.”

Our guide to yoroshiku onegaishimasu explains why the last phrase extends beyond “nice to meet you.”

Should you bow?

A small nod or bow may accompany a greeting, especially in polite settings. You do not need to calculate an exact angle for routine encounters. Face the person, speak clearly, and match the general level of formality.

Common mistakes

Using konnichiwa for every “hello”

Telephone calls, returning home, entering a shop, and beginning work each have their own common language. Translation categories do not make expressions interchangeable.

Using casual ohayō with everyone

The short form is natural where casual speech is established. With a teacher, new colleague, or unfamiliar adult, ohayō gozaimasu is safer.

Worrying about an exact cutoff

If the setting is clearly evening, use konbanwa. In a gray period, either greeting may occur. Natural timing is learned from communities, not a universal timetable.

A practical rule

Begin with the clock-based map, then notice the relationship and activity. Greetings do not merely label time; they acknowledge the kind of encounter beginning now.
