When a Japanese customer hears *irasshaimase*—“Welcome”—they usually do not stop to wonder whether the employee truly feels happy to see them. The employee is not necessarily putting any special emotion into it either. Neither side usually attaches much emotion to the phrase itself. Yet if no one acknowledges the customer when they enter, and there is not even a brief “Thank you” after payment, some people will come away thinking the service felt cold or rude.
Fixed phrases are common in Japanese customer service not because they are meant to express deep emotion, but because they maintain a basic form of politeness. Expressions such as *irasshaimase*, “Please wait a moment,” and “Thank you very much” mark the beginning and end of the interaction and show that the customer has not been ignored. People may not think deeply about each phrase, but when those phrases disappear completely, it can feel as though the basic courtesy has disappeared with them.
That is why a somewhat flat delivery is usually not a problem in a convenience store or chain shop. In fact, an employee who put intense emotion into every single *irasshaimase* might sound more unusual than sincere. The purpose of these phrases is not to display the employee’s personality. They help ensure that whoever is working can provide at least a minimum level of proper service. Customers do not consciously think, “This script makes me feel secure,” but if customers repeatedly encounter careless or unpleasant service at a shop, they may gradually stop going there.
These expressions are not special scripts used only by large chains. Small independent shops also use phrases such as *irasshaimase* and “Thank you very much.” The words themselves are usually much the same. What changes is the way they are delivered: the tone of voice, facial expression, smile, and the way the employee begins a conversation with the customer. A steady, neutral tone sounds natural in a convenience store. In a small shop, the same completely mechanical delivery may feel oddly out of place.
In Japanese customer service, the important difference is often not the wording itself but the amount of warmth that suits the setting. The same “Thank you very much” can serve as the basic minimum of courtesy in a chain store, while in a small shop it may reveal a little of the owner’s personality. Japanese customers tend to pick up that difference less from the literal meaning of the words than from the voice and expression behind them.
