Kotowaza were created by gaining experience and through recurring events over the years of existence of the Japanese people. The purpose of this study is to conduct a qualitative analysis of Japanese kotowaza in cognitive-linguistic discourse to divide idioms into categories and groups with specific sociocultural features. The paper focuses in detail on the semantic features of 20 kotowaza that use animal symbols as an idiomatic metaphor. In this paper, 10 proverbs with the central animal visualization, neko, were analyzed. Visionary metaphors are developed based on the comparison of cat's body parts and behavior with human qualities or characteristics of objects and phenomena. The analysis of the remaining 10 kotowaza showed that the meaning of imagery could originate from Chinese tradition and then change under the influence of Japanese style. Hence, it follows that the meanings of some kotowaza, or the animals they use, can be interpreted differently depending on context. However, the key meanings of proverbs are engrained in the national consciousness of native speakers. It was also observed that kotowaza used oxymoron. It is possible to gain a correct understanding of what kotowaza means through analyzing literal and idiomatic relations in the proverb. Each proverb has an animal symbol, the meaning of which is engrained and originates from the cultural and historical development of the Japanese nation. The practical application of the study lies in the fact that these findings can be used for further study of the special aspects of manifestation of sociocultural heritage at the linguistic level within the phraseology of the Japanese language.
