The most useful ways to say hi in Japanese are こんにちは (konnichiwa), おはようございます (ohayou gozaimasu), and こんばんは (konbanwa). The right choice depends on the time of day and the relationship between speakers.
Japanese greetings also change with the setting. A friend may use a short, relaxed expression, while a workplace, shop, school, or phone call calls for a different phrase. This guide explains what each greeting means and when it sounds natural.

Common ways to say hi and hello in Japanese
こんにちは (Konnichiwa) — hello
Konnichiwa is the standard greeting for daytime conversations. It works with acquaintances, coworkers, teachers, and people you are meeting in a polite everyday setting. It is often translated as “hello” or “good afternoon.”
The final は is written ha but pronounced wa in this expression. Use the full form when speaking to someone you do not know well; close friends may choose a more casual greeting instead.
おはようございます (Ohayou gozaimasu) — good morning
Ohayou gozaimasu is the polite way to say “good morning.” It is suitable for teachers, customers, colleagues, supervisors, and other people who deserve respectful language. In many workplaces, the expression can be used when starting a shift even if it is not early morning.
The shorter おはよう (ohayou) is familiar and casual. Use it with family, close friends, or people with whom you already have an informal relationship.
こんばんは (Konbanwa) — good evening
Konbanwa is a polite everyday greeting used in the evening. It is appropriate when meeting someone at night, including neighbors, acquaintances, and people in a formal or semi-formal setting. It is a greeting on arrival, not usually a replacement for a goodbye when leaving.
やあ (Yaa), よ (Yo), and おっす (Ossu) — casual greetings
Yaa and yo are relaxed ways to get a friend’s attention or say hi. Ossu is even more casual and associated with familiar groups, especially among young men and people sharing a strong informal bond. These expressions can sound abrupt with strangers, customers, teachers, or older people.
Greetings for specific situations
もしもし (Moshi moshi) — hello on the phone
Moshi moshi is the familiar “hello” used when answering or checking a telephone connection. It belongs to phone conversations, not ordinary face-to-face greetings. On a business call, the conversation usually moves quickly to a more specific introduction or a workplace expression.

お疲れさまです (Otsukaresama desu) — workplace greeting
Otsukaresama desu acknowledges someone’s work and is common between colleagues. It can function as a greeting when coworkers meet, as a transition during a work conversation, or as a parting expression after work. The shorter otsukare is more familiar.
いらっしゃいませ (Irasshaimase) — welcome in a shop
Irasshaimase is a customer-service welcome heard in shops, restaurants, and other businesses. Visitors normally do not need to repeat it. A simple nod or a polite response is enough when entering a store.
ただいま (Tadaima) — I am home
Tadaima is used when returning home or to a place where people are waiting for you. The person already inside commonly answers おかえり (okaeri) or the more polite おかえりなさい (okaerinasai). It is a set homecoming exchange, not a general translation of “hello.”
How formal should your Japanese greeting be?
| Situation | Natural choice | Meaning |
|---|---|---|
| Meeting an acquaintance during the day | こんにちは | Hello |
| Greeting a teacher, customer, or colleague in the morning | おはようございます | Good morning |
| Greeting a close friend in the morning | おはよう | Morning / good morning |
| Meeting someone in the evening | こんばんは | Good evening |
| Answering a phone call | もしもし | Hello |
| Speaking with a coworker | お疲れさまです | Thanks for your work |
| Entering your home after being away | ただいま | I am home |
If you are unsure, choose the polite standard expression. Konnichiwa is a safe daytime greeting, while ohayou gozaimasu and konbanwa cover morning and evening situations. A calm tone and a small bow matter as much as the vocabulary.
Regional and cultural notes
Japanese has regional speech varieties, and some communities use local forms of familiar greetings. Those expressions are not interchangeable with standard Japanese in every situation, so beginners should learn the standard forms first and treat dialect forms as local language rather than universal alternatives.
Greetings also depend on social distance. Japanese does not use one casual “hi” for every context: the same phrase can sound friendly among close friends and too blunt in a workplace. When in doubt, start politely and become more casual only when the relationship makes that change natural.
