In today's rapidly growing global economy, the usage of English has become ubiquitous. This preference for English in international business means that enterprises in non-native English-speaking countries are enthusiastic about English language education. Business people in Japan are no exception. This study seeks the perspectives of both Japanese and non-Japanese professionals from a wide range of careers on the English language proficiency of Japanese business people located in Singapore. By exploring the perspectives of these people, it provides suggestions on what kind of English language education should be provided to those who are going to use English in their future work, in order to prepare them to compete successfully in today's dynamic and challenging global business arena. This study is of particular relevance to Japanese people currently working, or looking to work, in the international business field, as well as educators and academics involved in English curriculumdevelopment in Japan.
