Can one sentence save a life? Haruka shares her personal story of overcoming depression and finding purpose in teaching, reminding us that education should help children accept themselves, not just become "useful." Her journey across continents redefines what it means to be a teacher. As a passionate educator and global citizen, Haruka believes that discovering the world is the first step to discovering yourself. With over seven years of experience as a primary and secondary teacher in Japan and more than two years as a JICA volunteer in Paraguay, she has dedicated her life to building bridges between cultures. Formerly a coordinator at the JICA Kyoto office, she now works in the JICA South America department, supporting sustainable development across the region. Her journey—from Japanese classrooms to South American communities—has shaped her vision of personal growth through global connection.
