The relationship in commerce and business between Japan and Malaysia has been rapidly developing and expanding in recent times. As a result, there is a dramatic rise in the demand for individuals who have Japanese language proficiency to work in Japanese companies. However, a very limited number of studies have focused on the requirements of Japanese language proficiency and importance of Japanese language skills among employees in JRCSM (Japanese Related Companies in Malaysia), especially in Southeast Asian context. This quantitative research investigated the level of importance of Japanese language proficiency in listening, speaking, reading, and writing among Malaysia Japanese Speaking Graduate Employees working at JRCSM. The results indicate that listening and speaking skills as the most important skills required in JRCSM workplace for communication purposes. The implications of this study indicate the need for the establishment of Japanese language degree programme at Malaysian universities to provide academic support for the Japanese language learners and to make sure that they are equipped with good Japanese listening, speaking, reading and writing skills.
