One key difference between American and Japanese greetings is the use of physical contact. Americans often greet each other with a handshake, a hug, or a pat on the back, depending on their relationship. Japanese greetings, however, typically involve bowing (ojigi) and avoid physical contact.

The depth and duration of the bow vary based on the relative social status of the individuals involved, with deeper and longer bows indicating greater respect. Direct eye contact is also generally avoided during the bow as it can be seen as disrespectful.
