A Native Japanese, Hanako was born in Tokyo and moved to New York City at the age of 5, spending most of her childhood there. She attended Columbia University in the City of New York, and studied Anthropology and Art History.
While in college, Hanako partook in various fashion internships, developing an undying love for fashion. In 2011, Hanako launched her own label ADEAM with a capsule collection of 15 pieces. In March 2012, ADEAM was invited by the Japanese government to present its Fall 2012 collection at Shanghai Fashion Week.
ADEAM showed its Spring 2013 collection at Tokyo Fashion Week, and debuted at New York Fashion Week for Fall 2013. Inspired by her two hometowns Tokyo and New York, Hanako continues to create collections that infuse art and wearability.
