Challenges and experiences to develop a Japanese language course for international medical students in Japan: Maximising acquisition of Japanese language by applying adult learning theories

Introduction: The International University of Health and Welfare (IUHW) School of Medicine was founded in 2017 with the intention of providing medical content in English a historical first in Japan. Twenty international medical students have been accepted annually, with the majority possessing less than beginner level Japanese language proficiency at the time of enrolment. However, proficiency in Japanese, especially in the context of medicine is required for academic success and program completion. To address this, the IUHW School of Medicine has developed a course in medical Japanese with the objective of facilitating international students' acquisition of medical Japanese and reinforcing such acquisition through various listening, speaking, reading, and writing activities. This study aims to describe the Japanese language education program for international students at the IUHW School of Medicine, with particular focus on the development of the curriculum and course content.Methods: The course is designed based on the following educational strategies and their applications: (a) Synchronisation of both medical and Japanese contents; (b) Collaborative learning; (c) Japanese output of medical content learned in English; (d) Practical output through making/giving a presentation and discussion with medical experts; (e) Detailed language feedback from language experts; (f) Reinforcing the vocabulary knowledge by writing; and (g) Building up vocabulary and expressions with relevant contents.Results: Our observations suggest that our international students have been able to continue their medical education in Japanese smoothly.Conclusion: The content-based instructional design that includes second language acquisition strategies may also be applicable to other Asian languages such as Korean and Chinese.
