Meaning & Definition

Okaerinasai is the greeting you say when someone returns home — the other half of a ritual exchange that marks the boundary between the outside world and the warmth of home. It is one of the most emotionally resonant phrases in Japanese daily life, spoken by the person who stayed behind to welcome the one who has just walked through the door.

Okaerinasai literally means something close to please come back or welcome back, and it functions as the standard polite response to tadaima (ただいま), the phrase a returning person calls out upon arriving home. The speaker of okaerinasai is always the one who has been waiting — a parent, spouse, roommate, or anyone present when the other person walks in. The phrase acknowledges the return and signals that the person is back in a safe, familiar place. In polite or formal contexts the full form okaerinasai is used; in casual everyday speech between family members it is often shortened to okaeri (おかえり). The two forms differ mainly in register, not in meaning — okaerinasai carries a slightly warmer, more deliberate tone, while okaeri is quick and relaxed.

How to Use It

The most important thing to understand about okaerinasai is that it always comes as a response — you never say it unprompted. The returning person speaks first with tadaima, and only then does the person at home reply with okaerinasai or okaeri. Using okaeri with family or close friends is completely natural; switching to okaerinasai signals a more careful or affectionate tone. Outside the home, you will also hear okaeri used when a colleague returns to the office after being out — in that setting okaeri (not the full okaerinasai) is typical. Learners sometimes try to use okaerinasai proactively or on its own, but doing so sounds unnatural; always wait for tadaima first.

Kanji Breakdown

おかえりなさい is most commonly written in hiragana in everyday use, but the kanji form お帰りなさい also exists. 帰 (kaeru) means to return or go home, carrying the sense of coming back to one’s own place. The honorific prefix お and the polite suffix なさい together elevate the phrase beyond a plain statement, giving it a welcoming, courteous feel.

Example Sentences

Cultural Context

The exchange of tadaima and okaerinasai is one of the defining rituals of Japanese home life. Unlike a simple greeting, this pair of phrases creates a moment of mutual acknowledgment — the returning person announces themselves, and the person at home confirms that the return has been noticed and welcomed. For many Japanese people, hearing okaerinasai as they walk through the door signals that they are no longer in the demanding public world but back in a space where they belong.

This greeting carries particular weight in Japanese family culture, where the home (ie, 家) has traditionally been understood as a sanctuary separate from work and social obligations. Okaerinasai is not just a pleasantry; it is a small act of care. In households where a parent waits for children to return from school, or a spouse waits for a partner working late, the phrase functions as an expression of relief and warmth as much as a formal greeting.

The phrase also appears in Japanese workplaces, where the shortened form okaeri is used when a colleague returns from an outside meeting or errand. In more formal companies or high-end service settings, staff may use the highly polished form okaerinasaimase (お帰りなさいませ) to greet returning guests or executives — a form that elevates the welcome to a level of deferential hospitality rarely heard in ordinary homes.
