After earning my degree from a university school of nursing, I began my career as a public health nurse in a local government, where I was primarily engaged in maternal and child health services as well as infectious disease control. Having aspired to work in international cooperation since high school, I took a personal development leave and was dispatched to Nepal for two years as a member of the Japan Overseas Cooperation Volunteers (JOCV). There, I witnessed firsthand the reality that, despite having established health systems and policies, many rural women were unable to benefit from them. This experience led me to question how people in vulnerable situations could access appropriate health services and lead healthy lives. I decided to pursue my studies at this university to acquire specialized knowledge and systematically develop practical intervention skills.
