Communication is a two-way process. The main elements that make up the communication process include message, channel, receiver and feedback. It is not an easy task to "decipher" what a person is actually saying or feeling at the present moment. The communication process refers to the combination of what you hear and see in the current situation, on the basis of which you draw a conclusion. Non-verbal communication develops trust, good relationship and facilitates transparency. Wrong body language creates suspicion, tension and confusion leading to conflict. Non-verbal communication has always fascinated human beings. Non-verbal communication is ubiquitous and influential, but in many ways ineffable. Most of the time, it is difficult to describe and study. Non-verbal communication is often difficult to be aware of in everyday life, and sometimes we only become aware when it goes wrong. Yet people have an extensive and deeply shared implicit understanding of nonverbal communication. If this were not the case, everyday life would be chaotic. Communication is therefore, in a broader sense, the exchange of information, the process of giving, transmitting and receiving information. Individuals form key impressions and inferences about other people based on nonverbal behavior. Non-verbal communication has the function of supplementing the verbal part, replacing the verbal action and repeating what was said. Every facial expression contributes to the overall meaning of what we say. The preciousness of culture and rich tradition are precisely what highlight Japanese culture, and even today it is the embodiment of the division into classes determined by origin and social status. An important role in raising children is played by the family, which traditionally transmits kindness in behavior from generation to generation. Japan differs from most countries in the world in terms of non-verbal communication, where these differences are most pronounced in private and business environments. This paper will present in more detail the most common forms of non-verbal communication and how it is applied in the business environment of Japan.
