irasshaimase
= formal welcome greeting used by staff when a customer enters a shop or restaurant
Step into almost any shop, restaurant, or store in Japan and you will instantly be greeted with a warm, clearly pronounced “irasshaimase” (いらっしゃいませ). It is the sound of Japanese hospitality — a formal, slightly ritualized welcome that signals you have entered a space where service is taken seriously.
Irasshaimase (いらっしゃいませ) is a highly formal honorific expression meaning “welcome” or “please come in,” used exclusively by staff addressing customers or guests. It is the imperative form of the honorific verb irassharu (いらっしゃる), which is the ultra-polite equivalent of the verbs “to be,” “to come,” and “to go.” The -mase ending adds a layer of formal politeness, making the whole expression extremely respectful. In practice, irasshaimase is not a greeting that requires or expects a verbal response — customers typically nod, make eye contact, or simply walk in without responding, which is perfectly natural. The expression is so deeply embedded in Japanese service culture that staff often call it out to the entire shop floor even when a customer is still at some distance, ensuring no one enters unacknowledged.
Visitors to Japan sometimes feel the urge to respond to irasshaimase with a greeting of their own, but this is not expected or necessary. A smile and nod is sufficient. Do not confuse irasshaimase with okaerinasai (おかえりなさい, “welcome home”) — that expression is used when someone returns home, not in a commercial setting. Also, while irasshaimase is the standard form, you may occasionally hear shortened casual variants like “irasshaimasee” (with a lengthened vowel) or even simply “irasshaimase!” called out with particular energy in izakayas and ramen shops.
いらっしゃいませ is written entirely in hiragana in everyday contexts and rarely appears in kanji. The base verb いらっしゃる can theoretically be written as 居らっしゃる but this is unusual in modern practice. The -mase (ませ) ending is a classical Japanese verb ending that adds formality and is retained in a small number of set expressions in modern Japanese, of which irasshaimase is the most commonly heard.

Irasshaimase is one of the most audible expressions of omotenashi — Japan’s philosophy of wholehearted, anticipatory hospitality. The word signals more than the simple fact of a customer’s arrival; it establishes the service relationship and sets the tone of the entire interaction. In high-end establishments like department stores or traditional restaurants, the greeting is delivered with a deep bow; in casual settings like convenience stores, it may be more perfunctory but is still obligatory as a professional standard.
The sound of irasshaimase has become so strongly associated with Japan in the global imagination that it features in travel documentaries, tourist guides, and social media content about Japan more than almost any other expression. Some travelers specifically look forward to the experience of being greeted this way as part of the Japanese service atmosphere. Interestingly, the greeting has inspired humorous adaptations — some shops in Japan have trained cats, dogs, and even robotic figures to greet customers, with “irasshaimase” occasionally playing from automated speakers as a tongue-in-cheek version of the tradition.
