Multiculturalism refers to the coexistence of different cultures within a society. The terms “Japanese culture” or “Chinese culture” are often used, but it’s not accurate to assume that there is only one culture in a country. Similarly, it’s not valid to assume that there is only one language in a region. Cultures and languages have always been diverse and multi-layered. There are no clear distinctions between different layers and styles, only a continuum of similarities and differences. This master’s program aims to explore the interface between these layers and styles. Students will first gain an understanding of actual phenomena and the intertwined historical origins of various regions through human contact and reading. They will then learn how people communicate in subtle similarities and differences and apply this knowledge to plan and execute cross-regional communication activities. Through continuous practice and reflection, they will develop their cognitive and practical abilities and complete their learning process with a master’s dissertation.
