This paper introduces our trial of MANGA-case training in business education not only to utilize variety of perspectives of learners but also to foster the ability to integrate one’s knowledge, experience and available information for executing an appropriate action. With greater globalization, it becomes more difficult to share common understandings about textbooks in a classroom, as various students have different backgrounds. It is necessary to share common understandings of a particular situation to reflect learners’ various viewpoints towards situations. From our experience with international MANGA workshop in several areas, MANGA shows the potential to be effective in global circumstances and applicable to any level and any area.
