Observing communicative aspects of English and Japanese, our research analyze characteristics of lexicon, sentence and discourse structure, and also examine properties of non-verbal behavior. Based on the findings and observations, we investigate communicative skills of English speakers and Japanese ones, which enables us to understand effective use of language and behavior and impressive synergy effects between them.

One of the topics of our research is to observe lexical selections in actual situations of English and Japanese communications and analyze them from the viewpoints of properties of speaker and hearer, their interpersonal relationship and their mental attitudes.

Another topic of our research is to observe construction selections in English and Japanese communications. By analyzing them from the viewpoints of properties of speaker and hearer, their interpersonal relationship and their mental attitudes, we can understand effective use of particular constructions in communicative contexts.

We also investigate proper application of the findings to linguistic education. With the help of information technology, we create multimodal knowledge contents combined with a knowledge database for the purpose of improving learners’ communicative skills.
