Objectives: Migrant technical intern trainees who migrate to Japan have become essential to the Japanese labour force, especially in rural areas. Persons in charge of supervising organisations and training coordinators both support the trainees’ health and daily lives during their stay in Japan. This support is significant for trainees as it helps them access and interact with Japanese society. This study explored the perspectives of persons in charge of female technical trainees regarding support for the latter’s health and daily lives.Materials and Methods: Semi-structured interviews were conducted with 14 persons in charge of female technical trainees, followed by a thematic analysis of the interview data to extract key themes.Results: Four primary themes emerged: fostered beliefs and roles, cultural considerations and health support, language considerations, and concerns about female trainees in relationships. These considerations and support developed solely through experience of persons in charge of female trainees. Additionally, those in charge expressed concerns about trainees being involved in a relationship. However, no specific measures, such as providing female trainees with information, have been taken.Conclusion: Persons in charge of female technical intern trainees need to be provided opportunities to learn about cultural considerations and providing health support for their trainees. Furthermore, the cooperation of health professionals with supervising organisations and training facilities is essential to promote the healthy lives of technical intern trainees. These insights can contribute to the development of an integrated community-based approach to support the health and daily lives of female trainees.
