We, a group of four delegates from Japan, participated in the fifth Japan-UK Primary Care Exchange Programme and visited the UK in October of 2018. This report highlights some differences between the UK and Japanese healthcare systems, such as working conditions for GPs and requirements for GP trainers, and what the Japan Primary Care Association can learn from them. We propose that the Japan Primary Care Association create opportunities to discuss and exchange views with other healthcare professionals, strengthen training programs for future GP trainers and define competencies for GP trainers in Japan.
