It is proposed that Master's in Business Administration (MBA) degree programs integrate Japanese language instruction in order to train business people to be sensitive to cultural differences and capable of operating effectively and comfortably in Japanese environments. The discussion begins by presenting some issues concerning traditional MBA program design and traditional liberal arts Japanese language programs, then discusses the importance of integrating the two disciplines. In particular, it is argued that neither program is sufficient in itself to prepare young Americans for the global market. The next section addresses the need for new instructional approaches to language instruction suitable for MBA students, particularly the need for authentic materials to develop practical language skills. Finally, the value of integrating cultural components into such curricula is discussed, and the importance of appropriate teacher training is highlighted. An additional recommendation is that two years of language study be a prerequisite for entry into an international MBA program and/or that an intensive language course begin before the MBA program itself, followed by a foreign internship and further language study during the program.
