You may sometimes see a Japanese person bowing repeatedly while talking on the phone, even though the person on the other end cannot see them. To a foreigner, this can look a little strange. But bowing on the phone is not a special rule of Japanese phone etiquette. In most cases, the person is not consciously thinking, “I should bow now.” Their body simply moves along with the polite words they are saying.
Expressions such as “thank you,” “I’m sorry,” and “I appreciate your help” are often accompanied by a bow in face-to-face conversation. When the conversation moves to the phone, that connection between words and movement does not suddenly disappear. The other person may not be able to see the bow, but the body does not seem to care much about that. When people use the same polite language they would use in person, their bodies may react in much the same way.
This tends to happen more often in formal situations, such as when speaking with a client, a superior, or someone to whom an apology or request is being made. A simple thank-you may produce only a slight dip of the head. During a serious apology, someone might bow much more deeply without even realizing it. If you asked them afterward exactly how far they bowed, they might not be able to tell you. The movement was never really planned.
With family members or close friends, this kind of bowing is less common because the conversation is usually more relaxed. Even then, some people may still move their heads out of habit. There is a great deal of individual variation. Japanese people who see someone bowing while talking on the phone usually do not find it unusual. If you start paying attention to it, you may notice it more often than you expected, but otherwise it blends easily into everyday behavior.
Not every small “bow” is actually a formal bow, either. Japanese people often move their heads slightly while saying things such as “yes,” “I see,” or “right” as a form of aizuchi, the small responses used to show that they are listening. On the phone, these movements can look like a series of little bows. What appears to be repeated bowing may actually be a mixture of politeness and ordinary listening responses.
There is no need to bow while speaking on the phone in Japan, and failing to do so is not rude. Not every Japanese person does it, and foreigners are certainly not expected to copy it. It is less a deliberate gesture toward an invisible listener than a physical response learned through years of face-to-face interaction, continuing even when the conversation is carried only by voice.
