The agency the authors belong to have preparatory Japanese classes for the participants who visit Japan to undertake technical training for several months. The Japanese classes aim to allow them to communicate through Japanese with people they meet during their training, and to come to understand Japanese customs and culture. We provide the activities outside the classroom to create opportunities for them to interact with people in a social environment. This paper reports the outcomes of these activities and investigates what the participants learned from them based on the results of questionnaires and hearings.
