When you first arrive in Japan, greetings like ohayou or konnichiwa are the first things you master. But there is a hidden layer to Japanese social interaction that happens at the front door. If you’ve ever been hosted by a Japanese family, you might have heard a chorus of ‘Itterasshai!’ as you stepped out onto the street. It’s not just a polite way of saying goodbye; it’s a prayer for your safe return.
The phrase is a contraction of ‘Itte irasshai’—a combination of the verb iku (to go) and irassharu (to come, honorable form). The cultural weight here is significant. In Japanese culture, the home is a sanctuary, and the world outside is viewed as unpredictable. By saying ‘Itterasshai,’ the person staying behind acknowledges that they expect—and desire—your safe homecoming. It transforms a mundane departure into an act of care.
The Ritual: Person A: ‘Ittekimasu!’ (I’m off!)
Person B: ‘Itterasshai!’ (Go and come back safely!)
If you want to understand how deep the cultural roots of connection go, consider our guides on Ohayou or the complex nuances of Honne to Tatemae. Much like those concepts, Itterasshai is about maintaining a social harmony that transcends simple transactional language.
Common Mistakes Foreigners Make
The most frequent error I see expats make is using Itterasshai in the wrong context. You should never use it in a professional setting. Telling your boss or a client ‘Itterasshai’ as they leave a meeting room is incredibly condescending—it implies you are the one in charge of their well-being or that they are a child returning home. In business, stick to ‘Otsukaresama desu’ or ‘Shitsurei shimasu.’
Another mistake? Saying it to someone who is leaving for an extended period, like a vacation. While it technically ‘works,’ it sounds slightly odd. We usually reserve this for the daily grind—the husband heading to the office, the child heading to school, or a friend stepping out for groceries.
Slang Variations and Variations
In casual, extremely close relationships, you might hear a shortened ‘Itterai!’ It sounds cute and is common among young couples or close friends living together. However, keep this strictly for informal settings. If you’re at a guesthouse or staying with a host family, sticking to the full ‘Itterasshai’ is safer and shows a higher level of respect for the household’s tradition.
Ultimately, Itterasshai is the acoustic embodiment of the Japanese focus on the ‘circle of life’—the idea that every departure is simply a prelude to a return. It is these small, daily rituals that define life here, turning every morning commute into a reaffirmation of the bonds that keep us connected.
