The subject of this article is the research of Japanese – English mimetic parallels in the key of the problem of translatability. The majority of linguists consider onomatopoeic and mimetic words to be untranslatable lexis, which causes a set of problems when translating. Situation becomes even more complicated as the onomatopoeic words of Japanese, though very widespread, remain low-studied layer of lexis and their translation into English requires quite a translational challenge because of the huge typological differences between these two languages. Nevertheless despite the mentioned above typological differences, the researching method of phonosemantic analysis can give translators the clue to find efficient methods of translating these lexical units, avoiding the loss of expressiveness and semantic meanings.
