Definition: O-jama shimasu (お邪魔します) literally translates to “I will disturb you.” In Japanese culture, it is the standard, indispensable phrase used when entering someone’s home, office, or private space. It isn’t just a greeting; it’s an admission of modesty and an acknowledgement of the host’s space.
When I first moved to Japan, I remember walking into a friend’s house in Kyoto and just saying konnichiwa. The silence that followed wasn’t necessarily hostile, but it was thick with unspoken social friction. My friend later told me that entering a house without acknowledging the intrusion feels like walking into a sanctuary without knocking. In Japan, space is sacred, and O-jama shimasu is the key that unlocks it.
Unlike the casual “Hello” or “Hey, I’m here” used in the West, this phrase carries a heavy dose of humility. You are essentially apologizing for your presence in their personal life. It is the ultimate social lubricant.
When to Use O-jama Shimasu
You should use this immediately after crossing the threshold (the genkan). Whether you are visiting a friend’s apartment, entering a boss’s office, or even popping into a colleague’s workspace, the phrase sets the tone for a respectful interaction. If you are leaving, the phrase shifts to the past tense: O-jama shimashita (Thank you for letting me disturb you). It is the perfect bookend to a visit.
Pro-Tip: Don’t just mutter it at the door. Say it clearly, look your host in the eye, and if you are entering a home, remove your shoes first. You cannot fully master this phrase if you neglect the ritual of the genkan.

Common Mistakes Foreigners Make
- Using it in public spaces: You don’t need to say this when entering a shop or a restaurant. It’s for private domains. Using it at a convenience store will just confuse the clerk.
- Forgetting the past tense: Never forget to use O-jama shimashita when you are putting on your shoes to leave. It shows you value their time and hospitality.
- Saying it too loudly: It’s a humble phrase. Keep your tone soft and respectful, not boisterous.
Slang and Variations
While the standard phrase is polite, you will hear variations depending on the relationship. In very casual, close-friend scenarios, people might shorten it to just O-jama! though I would advise sticking to the full phrase until you have been invited into someone’s home at least a dozen times. Conversely, in ultra-formal business settings, you might hear O-jama itashimasu, which is the humble (kenjougo) version of the verb, showing even deeper deference to a superior or client.
Host: “Douzo, agatte kudasai” (Please, come in.)
You: “Shitsurei shimasu. O-jama shimasu.” (Excuse me. I will disturb you.)
By mastering O-jama shimasu, you aren’t just memorizing a phrase—you are signaling that you understand the boundaries of Japanese life. It is a small gesture that speaks volumes about your respect for the local culture.
