How to Say Hello in Japanese: Konnichiwa and 12 Greetings Natives Actually Use

Hello in Japanese is こんにちは (konnichiwa), pronounced kon-nee-chee-wah. That is the answer, and now here is the part almost no guide tells you: konnichiwa is not an all-day hello. It is a daytime greeting, roughly 11 am to 5 pm, and it carries a faint layer of politeness that makes it slightly odd with people you are close to. Say konnichiwa to your best friend or to your own mother and you will get a strange look, the way an English speaker would react to "Good day to you" from a roommate. Japanese greetings are sorted by clock and by closeness, and once you see that grid, the whole system snaps into place.

The Essential Japanese Greetings

Two things worth noticing straight away. こんにちは has no informal version. Where English drops from "good afternoon" to "hi", Japanese simply stops greeting: friends meeting at 2 pm skip the hello entirely and open with the actual thing they wanted to say. And お疲れ様です does more work than any word on this list, which we will get to, because it is the greeting foreigners underuse the most.

Time of Day, and the Formality Ladder

Japanese slices the day into three greetings, and unlike Spanish, the cut points are about the sun rather than meals.

• おはようございます covers the morning, up to about 10 or 11 am. There is a beautiful exception: in workplaces where shifts are irregular, television, restaurants, theatre, construction, ohayō gozaimasu is said whenever you arrive, even at 9 pm. It means "first time I have seen you today", not "the sun is up".
• こんにちは takes over through the daylight hours until it gets dark.
• こんばんは starts once the light goes. It greets people, it does not send them to bed. For that you need おやすみなさい.

The formality ladder is easiest to see in the morning greeting, because it is the only one that has a full ladder:

• おはよう (ohayō), casual. Friends, family, a partner. Drop this on your boss and it is genuinely rude.
• おはようございます (ohayō gozaimasu), the standard polite form. Colleagues, neighbours, shopkeepers, anyone you do not know well.

Konnichiwa and konbanwa sit permanently at the polite end with no casual sibling, which is exactly why they feel wrong between close friends. The rule of thumb: if you can say おはよう to someone, you should not be saying こんにちは to them.

The Greetings Foreigners Never Learn but Japanese Use Constantly

This is the part that will change how you sound.

お疲れ様です (otsukaresama desu) is the single most used greeting in working Japan, and it is almost invisible in textbooks. Literally it is something like "you must be tired", meaning "I acknowledge your effort". In practice it is a universal work-hello, a work-goodbye, a thank you, and a punctuation mark. Passing a colleague in the corridor: otsukaresama desu. Opening an email: otsukaresama desu. Leaving at the end of the day: お疲れ様でした (past tense, otsukaresama deshita). If you work in Japan, you will say this fifty times a day and konnichiwa almost never.

いらっしゃいませ (irasshaimase) is the one that confuses everyone. It means "welcome, come in", and every shop, café and restaurant fires it at you the second you cross the threshold, sometimes in chorus. You do not answer it. It is not addressed to you as a person, it is addressed to you as a customer. A nod is generous. Learners who cheerfully reply irasshaimase back have effectively welcomed the staff into their own shop.

ただいま / おかえりなさい (tadaima / okaerinasai) is the home pair. You walk in and announce ただいま, "I'm back". Whoever is inside answers おかえりなさい, "welcome back", or just おかえり in casual families. Japanese homes have almost no equivalent of shouting a plain "hi" through the door. The pair is so automatic that people say tadaima to an empty apartment.

There is also 行ってきます / 行ってらっしゃい (ittekimasu / itterasshai) for leaving the house. Same reflex, opposite direction.

Pronunciation: What the Romaji Hides

Three details do most of the damage.

こんにちは is kon-ni-chi-wa, with a held "n". That double n is not decoration. Japanese timing is built on equal beats, and ん is a full beat of its own: ko-n-ni-chi-wa is five beats, not four. English speakers crush it into "konichiwa" and instantly sound foreign. Same with おはようございます: the ō in ohayō is a long vowel, two beats, not one.

The は at the end is read "wa", not "ha". It is a fossil: konnichiwa and konbanwa were once the openings of full sentences ("as for today...", "as for this evening..."), and the topic particle は survived the amputation. That is also why you write こんにちは and not こんにちわ.

Japanese has pitch accent, not stress. You do not hammer a syllable louder, you move the tone up or down. Konnichiwa is not KON-ni-chi-wa. Flatten your English stress instinct and let the pitch do the shaping instead.

This is exactly where written guides run out of road. Romaji cannot teach your mouth the real sounds, and it certainly cannot teach it the pitch, because none of it is on the page. The only fix is to hear a native say the whole phrase, then say it back out loud, several times, until the beats stop feeling wrong. That listen and repeat loop is called shadowing, and it is the fastest way to turn a phrase you recognise into one you can produce under pressure. It is how the Hyperpolyglot app handles every phrase across its 55 languages: real sentences, native audio, looped until they come out automatically. Available on iOS, Android, and Web.

Common Mistakes to Avoid

1. Saying こんにちは at 8 am. Before roughly 11, it is おはようございます. After dark, こんばんは. Konnichiwa has a shift, and it does not cover the whole day.
2. Saying こんにちは to your best friend. It is too polite for intimacy. Between close friends, either use おはよう in the morning or skip the greeting and start talking.
3. Saying もしもし in person. Moshi moshi is phone-only. Face to face it lands somewhere between "testing, testing" and "hello? anybody home?", which is charming exactly once.
4. Bowing on the phone. Everyone does it eventually. Japanese people do it too. It is not a mistake so much as a sign you have caught the reflex, but do not consciously build it in.
5. Using さようなら as a normal goodbye. Sayōnara carries real finality, closer to "farewell". Say it to a colleague on a Tuesday and you sound like you are quitting.

Bonus: How to Say Goodbye in Japanese

• さようなら▶ (sayōnara), the one every learner knows and natives rarely use. It implies a long or permanent parting. Schoolchildren say it to teachers. Adults mostly do not.
• じゃあね▶ (jā ne), "see ya", the real everyday casual goodbye. Also またね (mata ne).
• また明日▶ (mata ashita), "see you tomorrow", warm and extremely common.
• お疲れ様でした▶ (otsukaresama deshita), the standard way to leave any workplace.
• 失礼します▶ (shitsurei shimasu), "excuse me for leaving", polite, for offices and hanging up on someone senior.

Learn こんにちは, おはようございます, こんばんは and お疲れ様です with real audio, drill them until they are reflexes rather than translations, and you will already sound less like a phrasebook than most learners three years in.
