The meaning of konnichiwa (こんにちは) in English is “hello”, “good afternoon”, or “good day”. It’s a common Japanese greeting used during the daytime, typically from late morning to early evening (around 10 AM – 6 PM). Since it’s a polite phrase, it’s best suited for neutral and formal situations.
If you want to understand the true meaning of the Japanese greeting konnichiwa, where it comes from, and how Japanese people actually use it in real life, keep reading. I will show you exactly when to use it, when to avoid it, and the most natural Japanese replies and responses, so you can greet others naturally and sound like a native speaker.
Konnichiwa Meaning: How to Use & Reply (Japanese Greetings)
1. What Does Konnichiwa Mean in Japanese?
Konnichiwa (こんにちは) is a Japanese greeting that means:
- hello
- good day
- good afternoon
Just like “good afternoon” in English, konnichiwa is used to greet someone during the daytime.
However, there is an even deeper meaning behind the word konnichiwa that comes from its original usage in Japanese.
Today, konnichiwa is almost always written in hiragana:
- こんにちは (hiragana, common)
But it can also be written in kanji:
- 今日は (kanji, rare)
When written as 今日は, it can be read in two ways:
- こんにちは (konnichiwa)
- 今日は (kyou wa)
The word kyou (今日, kyou) means “today“, and wa (は) is a particle that marks the topic of a Japanese sentence.
Please note that the particle wa is actually written with the hiragana syllable ha, and is just pronounced “wa“.
So the correct spelling in Japanese is actually “konnichiha“. However, to match the correct pronunciation, it is commonly written as “konnichiwa“.
- 今日 (きょう, kyou, “today”)
- は (ha/wa, particle, topic marker)
Together, kyou wa (今日は, きょうは) means:
“Today…”
“Today is…”
“As for today…”
In the past, Japanese people greeted each other with a full sentence such as:
Kyou wa gokigen ikaga desu ka?
今日はご機嫌いかがですか？
きょう は ごきげん いかが です か？
How are you doing today?
Over time, this long and formal greeting was shortened, eventually becoming the modern greeting konnichiwa (こんにちは).
Greeting | Japanese | Meaning |
|---|---|---|
konnichiwa | こんにちは (今日は) | hello good day good afternoon |
Kyou wa gokigen ikaga desu ka? | 今日はご機嫌 いかがですか？ | How are you today? How are you doing today? How are you feeling today? |
2. Is Konnichiwa Formal or Casual?
Konnichiwa (こんにちは) is a polite and neutral greeting, often used in formal or semi-formal situations.
It is commonly used with
- strangers
- coworkers,
- teachers
- people you don’t know well.
While it can be used with friends, it often sounds stiff, distant, or cold, and may feel unnatural in close relationships.

3. When Do You Use Konnichiwa?
Konnichiwa (こんにちは) is typically used from late morning until early evening:
- from 10-11 AM
- until sunset (around 5-6 PM)
Use konnichiwa during the daytime.
When NOT to Use Konnichiwa?
You generally don’t use konnichiwa:
- early in the morning
→ use ohayou (おはよう)
→ or ohayou gozaimasu (おはようございます) - in the evening or at night
→ use konbanwa (こんばんは)
These rules aren’t strict, and some people may use konnichiwa slightly earlier or later, but this is the natural guideline.
