The foreign skills internship system is aimed at contributing to the economic and industrial development of developing countries. Japanese enterprises receive young workers from developing countries for physical training and impart skills, technologies, and knowledge during a certain period of time. According to this system, the skills learned by skill interns can not only be used for themselves, but also for the economic development of their country after returning home. The residency qualification for skill interns is "specific activities". After completing one month of training, the trainees can enter the skill internship by changing their residency qualification from "training" to "specific activities".
