In the process of human civilization, the exchange of ideas and feelings is achieved through language. Language is the carrier as well as the expression of culture. Language enriches culture, and sometimes overdrawn culture. Japanese expression, full of modest, patience and respect, reflects the character of Japanese culture: inclusion, calm and introvert, and pursuit of benefits. The author attempts to study the overdraft phenomenon, local characteristics, and new trends of the Japanese language to explore the value of Japanese culture. Also, the researcher analyzes the various expressions in Japanese, the development of Japanese language and culture to grasp the characteristics and content of Japanese language and culture, with a view to promote the SinoJapanese cultural exchanges and communication.
