The article considers the influence of virtual communication in social networks on the lexical and orthographic change of oral speech representation. The development of computer technologies creates groups of interest, forums and social networks in the Internet where the language of virtual communication becomes more variable moving from its being symbolic to a more creative one, when users get the opportunity not just to exchange short messages but express their opinion. A new sphere of communication originates a new lexical layer of transformers and promotes the convergence of written and oral types of speech interaction. The analysis of correspondence in social networks and examples from Japanese sources have showed that the language of Japanese politeness Keigo is not used in networks which can create certain difficulties in choosing the right forms in real communication. Conversely, simple or familiar forms allowed in written language are scarce and their automatic transfer to everyday life can become a hindrance to establishing social contacts. Actively integrating in the Japanese language neologisms most often conform to the norms of Japanese phonetics and grammar, but they cause significant deviations in a written fixation of the transmitted text. The lack of a visual contact in social networks forms a written oral speech, the analysis and consideration of which is important for an adequate perception of information and for a better orientation in the Japanese Internet space.
